Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation The accompanying unaudited interim financial statements of the Federal Home Loan Bank of Atlanta (Bank) have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). To prepare the financial statements in conformity with GAAP, management must make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements and income and expenses during the reporting period. Actual results could be different from these estimates. The foregoing interim financial statements are unaudited; however, in the opinion of management, all adjustments, consisting only of normal recurring adjustments necessary for a fair statement of the results for the interim periods, have been included. The results of operations for interim periods are not necessarily indicative of results to be expected for the year ending 2020 , or for other interim periods. The unaudited interim financial statements should be read in conjunction with the audited financial statements for the year ended December 31, 2019 , which are contained in the Bank’s 2019 Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC) on March 5, 2020 (Form 10-K). The Bank has certain financial instruments, including derivative instruments and securities purchased under agreements to resell, that are subject to offset under master netting arrangements or by operation of law. Additional information regarding derivative instruments is provided in Note 11 — Derivatives and Hedging Activities to the Bank’s interim financial statements. The Bank does not have any offsetting liabilities related to its securities purchased under agreements to resell for the periods presented. Based on the fair value of the related securities held as collateral, the securities purchased under agreements to resell were fully collateralized for the periods presented. Refer to Note 2 — Summary of Significant Accounting Policies to the Bank’s 2019 audited financial statements for a description of all the Bank’s significant accounting policies. There have been no changes to these policies as of March 31, 2020 , except for policy updates related to new accounting guidance pertaining to the measurement of credit losses on financial instruments which is described below. Beginning on January 1, 2020, the Bank adopted new accounting guidance pertaining to the measurement of credit losses on financial instruments that requires a financial asset or group of financial assets measured at amortized cost to be presented at the net amount expected to be collected. The new guidance also requires credit losses relating to these financial instruments as well as available-for-sale securities to be recorded through the allowance for credit losses. Key changes as compared to prior accounting guidance are detailed below. Consistent with the modified retrospective method of adoption, the prior period has not been revised to conform to the new basis of accounting. Refer to Note 2 — Summary of Significant Accounting Policies to the Bank’s 2019 audited financial statements for information on the prior accounting treatment. Interest-bearing Deposits, Securities Purchased under Agreements to resell, and Federal Funds Sold . Interest-bearing deposits, securities purchased under agreements to resell, and federal funds sold provide short-term liquidity and are carried at amortized cost. Accrued interest receivable is recorded separately on the Statements of Condition. These investments are generally transacted with counterparties that have received a credit rating of triple-B or greater (investment grade) by a nationally recognized statistical rating organization (NRSRO) including the the following: Standard and Poor’s (S&P), Moody’s Investors Service (Moody’s), and Fitch Ratings. All of these investments were with counterparties rated investment grade as of March 31, 2020. These investments are evaluated quarterly for expected credit losses. If applicable, an allowance for credit losses is recorded with a corresponding credit loss expense (or reversal of credit loss expense). The Bank uses the collateral maintenance provision practical expedient to evaluate potential credit losses related to securities purchased under agreements to resell. Consequently, a credit loss would be recognized if there is a collateral shortfall which the Bank does not believe the counterparty will replenish in accordance with its contractual terms. The credit loss would be limited to the difference between the fair value of the collateral and the investment’s amortized cost. Securities purchased under agreements to resell are short-term and are structured such that they are evaluated regularly to determine if the market value of the underlying securities decreases below the market value required as collateral (i.e. subject to collateral maintenance provisions). If so, the counterparty must place an equivalent amount of additional securities as collateral or remit an equivalent amount of cash, generally by the next business day. The Bank did not have any securities purchased under agreements to resell as of March 31, 2020. Federal funds sold are unsecured loans that are generally transacted on an overnight term. All investments in interest-bearing deposits and federal funds sold were repaid or expected to be repaid according to the contractual terms as of March 31, 2020 and December 31, 2019. No allowance for credit losses was recorded for these assets as of March 31, 2020 and December 31, 2019. The carrying values of interest-bearing deposits excludes accrued interest receivable that was not material as of March 31, 2020 and December 31, 2019. The carrying values of federal funds sold excludes accrued interest receivable of $3 and $10 as of March 31, 2020 and December 31, 2019, respectively. Held-to-maturity Securities . Securities that the Bank has both the ability and intent to hold to maturity are classified as held-to-maturity and carried at amortized cost, which is original cost net of periodic principal repayments and amortization of premiums and accretion of discounts. Accrued interest receivable is recorded separately on the Statements of Condition. Held-to-maturity securities are evaluated quarterly for expected credit losses on a pool basis unless an individual assessment is deemed necessary because the securities do not possess similar risk characteristics. If applicable, an allowance for credit losses is recorded with a corresponding credit loss expense (or reversal of credit loss expense). The allowance for credit losses excludes uncollectible accrued interest receivable, which is measured separately. Prior to January 1, 2020, credit losses were recorded as a direct write-down of the held-to-maturity security carrying value. The Bank’s held-to-maturity securities consist of U.S. agency obligations, government-sponsored enterprise debt obligations, state or local housing agency debt obligations, and MBS issued by the Government National Mortgage Association (Ginnie Mae), the Federal Home Loan Mortgage Corporation (Freddie Mac), and the Federal National Mortgage Association (Fannie Mae) that are backed by single-family or multifamily mortgage loans. The Bank only purchase securities considered investment quality. All of these investments were rated double-A, or above, by a NRSRO as of March 31, 2020, based on the lowest long-term credit rating for each security. The Bank evaluates its held-to-maturity securities for impairment on a collective, or pooled basis unless an individual assessment is deemed necessary because the securities do not possess similar risk characteristics. The Bank has not established an allowance for credit loss on any of its held-to-maturity securities as of March 31, 2020 because the securities: (1) were all highly-rated and/or had short remaining terms to maturity, (2) had not experienced, nor did the Bank expect, any payment default on the instruments, and (3) in the case of U.S., government-sponsored enterprises, or other agency obligations, carry an implicit or explicit government guarantee such that the Bank considers the risk of nonpayment to be zero. Advances . Advances are carried at amortized cost, which is original cost net of periodic principal repayments and amortization of premiums and accretion of discounts (including discounts related to the Affordable Housing Program and Economic Development and Growth Enhancement Program), net deferred fees or costs, and fair value hedge adjustments. Accrued interest receivable is recorded separately on the Statements of Condition. The advances are evaluated quarterly for expected credit losses. If applicable, an allowance for credit losses is recorded with a corresponding credit loss expense (or reversal of credit loss expense). Refer to Note 2 — Summary of Significant Accounting Policies to the Bank’s 2019 audited financial statements for details on the allowance methodologies related to advances. Mortgage Loans Held for Portfolio . Mortgage loans held for portfolio are recorded at amortized cost, which is original cost, net of periodic principal repayments and amortization of premiums and accretion of discounts, fair value hedge adjustments on loans initially classified as mortgage loan commitments, and direct write-downs. Accrued interest receivable is recorded separately on the Statements of Condition. The Bank performs at least quarterly an assessment of its mortgage loans held for portfolio to estimate expected credit losses. If applicable, an allowance for credit losses is recorded with a corresponding credit loss expense (or reversal of credit loss expense). The Bank measures expected credit losses on mortgage loans on a collective basis, pooling loans with similar risk characteristics. If a mortgage loan no longer shares risk characteristics with other loans, it is removed from the pool and evaluated for expected credit losses on an individual basis. When developing the allowance for credit losses, the Bank measures the estimated loss over the remaining life of a mortgage loan, which also considers how the Bank’s credit enhancements mitigate credit losses. If a loan was purchased at a discount, the discount does not offset the allowance for credit losses. The allowance excludes uncollectible accrued interest receivable, as the Bank write-off accrued interest receivable by reversing interest income if a mortgage loan is placed on nonaccrual status. Refer to Note 2 — Summary of Significant Accounting Policies to the Bank’s 2019 audited financial statements for details on the allowance methodologies related to mortgage loans. Off-Balance Sheet Credit Exposures. The Bank evaluates its off-balance sheet credit exposure on a quarterly basis for expected credit losses. If deemed necessary, an allowance for expected credit losses on these off-balance sheet exposures is recorded in other liabilities with a corresponding credit loss expense (or reversal of credit loss expense). The Bank monitors the creditworthiness of its standby letters of credit based on an evaluation of the member. In addition, standby letters of credit are fully collateralized from the time of issuance. The Bank has established parameters for the measurement, review, classification, and monitoring of credit risk related to these standby letters of credit that result in an internal credit rating, which focuses primarily on an institution’s overall financial health and takes into account the quality of assets, earnings, and capital position. In general, borrowers categorized into the highest risk rating category have more restrictions on the types of collateral that they may use to secure standby letters of credit, may be required to maintain higher collateral maintenance levels and deliver loan collateral, and may face more stringent collateral reporting requirements. Based on the Bank’s credit analyses and collateral requirements, the Bank does not deem it necessary to record any additional liability on the Statements of Condition for these commitments as of March 31, 2020.

Debt Securities, Held-to-maturity [Abstract]
Held-to-maturity Securities	Held-to-maturity Securities During the three-months ended March 31, 2020, for strategic, economic and operational reasons, the Bank sold all of its held-to-maturity private-label MBS. The amortized cost of the held-to-maturity private-label MBS sold was $192. Proceeds from the sale of the held-to-maturity private-label MBS totaled $195, which resulted in a net realized gain of $3. For each of the held-to-maturity securities which were sold, the Bank had previously collected at least 85 percent of the principal outstanding at the time of acquisition due to prepayments or scheduled prepayments over the term of the security. As such, the sales were considered maturities for purposes of security classification. There were no sales of held-to-maturity securities during the three-months ended March 31, 2019. Major Security Types. The following table presents held-to-maturity securities.

Derivatives and Hedging Activities	3 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	Derivatives and Hedging Activities Nature of Business Activity The Bank is exposed to interest-rate risk primarily from the effect of interest-rate changes on its interest-earning assets and on its interest-bearing liabilities that finance these assets. To mitigate the risk of loss, the Bank has established policies and procedures, which include guidelines on the amount of exposure to interest-rate changes that it is willing to accept. In addition, the Bank monitors the risk to its interest income, net interest margin, and average maturity of its interest-earning assets and funding sources. The goal of the Bank’s interest-rate risk management strategies is not to eliminate interest-rate risk, but to manage it within appropriate limits. The Bank enters into derivatives to manage the interest-rate risk exposure that is inherent in its otherwise unhedged assets and funding sources, to achieve the Bank’s risk management objectives, and to act as an intermediary between its members and counterparties. The Bank transacts most of its derivatives with large banks and major broker-dealers. Some of these banks and broker-dealers or their affiliates buy, sell, and distribute consolidated obligations. The Bank’s over-the-counter derivatives transactions may either be (1) uncleared derivatives, which are executed bilaterally with a counterparty; or (2) cleared derivatives, which are cleared through a Futures Commission Merchant (clearing agent) with a Derivatives Clearing Organization (Clearinghouse). Once a derivatives transaction has been accepted for clearing by a Clearinghouse, the derivatives transaction is novated, and the executing counterparty is replaced with the Clearinghouse as the counterparty. The Bank is not a derivatives dealer and does not trade derivatives for short-term profit. For additional information on the Bank’s derivatives and hedging activities, see Note 17—Derivatives and Hedging Activities to the 2019 audited financial statements contained in the Bank’s Form 10-K. Financial Statement Effect and Additional Financial Information Derivative Notional Amounts. The notional amount of derivatives serves as a factor in determining periodic interest payments or cash flows received and paid. However, the notional amount of derivatives represents neither the actual amounts exchanged nor the overall exposure of the Bank to credit and market risk; the overall risk is much smaller. The risks of derivatives can be measured meaningfully on a portfolio basis that takes into account the counterparties, the types of derivatives, the items being hedged, and any offsets between the derivatives and the items being hedged. The following table presents the notional amount, fair value of derivative instruments, and total derivative assets and liabilities. Total derivative assets and liabilities include the effect of netting adjustments and cash collateral. For purposes of this disclosure, the derivative values include the fair value of derivatives and the related accrued interest. As of March 31, 2020 As of December 31, 2019 Notional Amount of Derivatives Derivative Assets Derivative Liabilities Notional Amount of Derivatives Derivative Assets Derivative Liabilities Derivatives in hedging relationships: Interest-rate swaps (1) $ 94,576 $ 70 $ 631 $ 73,637 $ 71 $ 221 Derivatives not designated as hedging instruments: Interest-rate swaps (1) 611 11 3 478 5 1 Interest-rate caps or floors 7,083 1 1 7,084 — — Total derivatives not designated as hedging instruments 7,694 12 4 7,562 5 1 Total derivatives before netting and collateral adjustments $ 102,270 82 635 $ 81,199 76 222 Netting adjustments and cash collateral (2) 907 (625 ) 304 (215 ) Derivative assets and derivative liabilities $ 989 $ 10 $ 380 $ 7 ___________ (1) Includes variation margin for daily settled contracts of $1,575 and $503 as of March 31, 2020 and December 31, 2019 , respectively.

For uncleared derivatives, the degree of credit risk depends on the extent to which master netting arrangements are included in such contracts to mitigate the risk. The Bank requires collateral agreements with collateral delivery thresholds on all uncleared derivatives. Additionally, collateral related to derivatives with member institutions includes collateral assigned to the Bank, as evidenced by a written security agreement, and held by the member institution for the benefit of the Bank. Certain of the Bank’s uncleared derivative instruments contain provisions that require the Bank to post additional collateral with its counterparties if there is deterioration in the Bank’s credit rating. If the Bank’s credit rating is lowered by a NRSRO, the Bank may be required to deliver additional collateral on uncleared derivative instruments in net liability positions. The aggregate fair value of all uncleared derivative instruments with credit-risk-related contingent features that were in a net liability position (before cash collateral and related accrued interest) as of March 31, 2020 was $10 , for which the Bank was not required to post collateral as of March 31, 2020 . If the Bank’s credit ratings had been lowered from its current rating to the next lower rating, the Bank would have been required to deliver $5 of collateral at fair value to its uncleared derivative counterparties as of March 31, 2020 . For cleared derivatives, the Clearinghouse is the Bank’s counterparty. The Clearinghouse notifies the clearing agent of the required initial and variation margin, and the clearing agent notifies the Bank. The Bank utilizes two Clearinghouses for all cleared derivative transactions, LCH Ltd. and CME Clearing. At both Clearinghouses, variation margin is characterized as daily settlement payments, and initial margin is considered cash collateral. Because the Bank is required to post initial and variation margin through the clearing agent to the Clearinghouse, it exposes the Bank to institutional credit risk if the clearing agent or the Clearinghouse fails to meet its obligations. The use of cleared derivatives is intended to mitigate credit risk exposure because a central counterparty is substituted for individual counterparties, and collateral/payments is posted daily through a clearing agent for changes in the fair value of cleared derivatives. The Bank has analyzed the enforceability of offsetting rights incorporated in its cleared derivative transactions and determined that the exercise of those offsetting rights by a non-defaulting party under these transactions should be upheld under applicable law upon an event of default, including a bankruptcy, insolvency, or similar proceeding involving the Clearinghouse or the Bank’s clearing agent, or both. Based on this analysis, the Bank presents a net derivative receivable or payable for all of its transactions through a particular clearing agent with a particular Clearinghouse. The Bank presents derivative instruments and the related cash collateral that is received or pledged, plus the associated accrued interest, on a net basis by clearing agent and/or by counterparty when it has met the netting requirements. The following table presents the fair value of derivative instruments meeting or not meeting netting requirements, including the related collateral received from or pledged to counterparties.

Fair Value Disclosures [Abstract]
Estimated Fair Values	Estimated Fair Values The Bank records trading securities, available-for-sale securities, derivative assets and liabilities, and grantor trust assets (publicly-traded mutual funds) at estimated fair value on a recurring basis. Fair value is defined under GAAP as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The transaction to sell the asset or transfer the liability is a hypothetical transaction at the measurement date, considered from the perspective of a market participant that holds the asset or owes the liability. In general, the transaction price will equal the exit price and therefore, represents the fair value of the asset or liability at initial recognition. In determining whether a transaction price represents the fair value of the asset or liability at initial recognition, each reporting entity is required to consider factors specific to the transaction, the asset or liability, the principal or most advantageous market for the asset or liability, and market participants with whom the entity would transact in the market. A fair value hierarchy is used to prioritize the inputs of valuation techniques used to measure fair value. The inputs are evaluated, and an overall level for the fair value measurement is determined. This overall level is an indication of how market-observable the fair value measurement is and defines the level of disclosure. In order to determine the fair value or the exit price, entities must determine the unit of account, highest and best use, principal market, and market participants. These determinations allow the reporting entity to define the inputs for fair value and level of hierarchy. Outlined below is the application of the “fair value hierarchy” to the Bank’s financial assets and liabilities that are carried at fair value or disclosed in the notes to the financial statements. Level 1 - inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. An active market for the asset or liability is a market in which the transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. The Bank carried grantor trust assets at fair value hierarchy Level 1 as of March 31, 2020 and December 31, 2019 . Level 2 - inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. The Bank carried trading securities and derivatives at fair value hierarchy Level 2 as of March 31, 2020 and December 31, 2019 . Level 3 - inputs to the valuation methodology are unobservable and significant to the fair value measurement. Unobservable inputs are supported by limited market activity and reflect the entity’s own assumptions. The Bank carried available-for-sale securities at fair value hierarchy Level 3 as of December 31, 2019 . The Bank utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. For financial instruments carried at fair value, the Bank reviews the fair value hierarchy classification of financial assets and liabilities on a quarterly basis. Changes in the observability of the valuation attributes may result in a reclassification of certain financial assets or liabilities within the fair value hierarchy. Such reclassifications are reported as transfers in/out at fair value as of the beginning of the quarter in which the changes occur. There were no such transfers during the periods presented. Estimated Fair Value Measurements on a Recurring Basis. The following tables present, for each fair value hierarchy level, the Bank’s financial assets and liabilities that are measured at fair value on a recurring basis on its Statements of Condition.

The following table presents a reconciliation of available-for-sale securities that are measured at fair value on a recurring basis using significant unobservable inputs (Level 3). For the Three Months Ended March 31, 2020 2019 Balance, beginning of period $ 684 $ 865 Total (losses) gains realized and unrealized: (1) Net realized gains from sale of available-for-sale securities 82 — Net impairment losses recognized in earnings — (1 ) Included in other comprehensive loss (41 ) (8 ) Accretion of credit losses in net interest income 1 15 Sales (726 ) — Settlements — (48 ) Balance, end of period $ — $ 823 ____________ (1) Related to available-for-sale securities held at period end. Described below are the Bank’s fair value measurement methodologies for financial assets and liabilities that are measured at fair value on a recurring or nonrecurring basis on the Statements of Condition and categorized within Level 2 and Level 3 of the fair value hierarchy. Investment securities . The Bank obtains prices from multiple designated third-party pricing vendors, when available, to estimate the fair value of its investment securities. The pricing vendors use various proprietary models to price investment securities. The inputs to those models are derived from various sources including, but not limited to, the following: benchmark yields, reported trades, dealer estimates, issuer spreads, benchmark securities, bids, offers, and other market-related data. Since many investment securities do not trade on a daily basis, the pricing vendors use available information as applicable, such as benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing to determine the prices for individual securities. Each pricing vendor has an established challenge process in place for all investment securities valuations, which facilitates resolution of potentially erroneous prices identified by the Bank. The Bank periodically conducts reviews of its pricing vendors to confirm and further augment its understanding of the vendors’ pricing processes, methodologies, and control procedures for U.S. agency MBS. The Bank’s valuation technique for estimating the fair value of its investment securities first requires the establishment of a “median” price for each security. All prices that are within a specified tolerance threshold of the median price are included in the “cluster” of prices that are averaged to compute a “resultant” price. All prices that are outside the threshold (“outliers”) are subject to further analysis (including, but not limited to, comparison to prices provided by an additional third-party valuation service, prices for similar securities, and/or non-binding dealer estimates) to determine if an outlier is a better estimate of fair value. If an outlier (or some other price identified in the analysis) is determined to be a better estimate of fair value, then the outlier (or the other price as appropriate) is used as the final price rather than the resultant price. Alternatively, if the analysis does not provide evidence that an outlier is more representative of the fair value, and the resultant price is the best estimate, then the resultant price is used as the final price. In all cases, the final price is used to determine the fair value of the security. If all prices received for a security are outside the tolerance threshold level of the median price, then there is no resultant price, and the final price is determined by an evaluation of all outlier prices as described above. Multiple third-party vendor prices were received for a majority of the Bank’s investment securities holdings, and the final prices for those securities were computed by averaging the prices received as of March 31, 2020 and December 31, 2019 . Based on the Bank’s review of the pricing methods and controls employed by the third-party pricing vendors and the relative lack of dispersion among the vendor prices (or the Bank’s additional analysis in those instances in which there were outliers or significant yield variances), the Bank believes that its final prices are representative of the prices that would have been received if the assets had been sold at the measurement date (i.e., exit prices) and further, that the fair value measurements are classified appropriately in the fair value hierarchy. Based on the lack of significant market activity for private-label MBS, the fair value measurement for those securities were classified as Level 3 within the fair value hierarchy as of December 31, 2019 . Derivative assets and liabilities. The Bank calculates the fair values of interest-rate related derivatives using a discounted cash flow analysis which utilizes market-observable inputs. The inputs for interest-rate related derivatives uses the Overnight Index Swap curve for collateralized derivatives. Derivative instruments are transacted primarily in the institutional dealer market and priced with observable market assumptions at a mid-market valuation point. The Bank does not provide a credit valuation adjustment based on aggregate exposure by derivative counterparty when measuring the fair value of its derivatives. This is because the collateral provisions pertaining to the Bank’s derivatives obviate the need to provide such a credit valuation adjustment. The fair values of the Bank’s derivatives take into consideration the effects of legally enforceable master netting agreements, where applicable, that allow the Bank to settle positive and negative positions and offset cash collateral with the same counterparty on a net basis. The Bank and each uncleared derivative counterparty have collateral thresholds that take into account both the Bank’s and the counterparty’s credit ratings. As a result of these practices and agreements, the Bank has concluded that the impact of the credit differential between the Bank and its derivative counterparties was mitigated to an immaterial level, and no further adjustments were deemed necessary to the recorded fair values of derivative assets and liabilities on the Statements of Condition as of March 31, 2020 and December 31, 2019 . The following estimated fair value amounts have been determined by the Bank using available market information and the Bank’s best judgment of appropriate valuation methods. These estimates are based on pertinent information available to the Bank as of March 31, 2020 and December 31, 2019 . Although the Bank uses its best judgment in estimating the fair values of these financial instruments, there are inherent limitations in any estimation technique or valuation methodology. For example, because an active secondary market does not exist for a portion of the Bank’s financial instruments, in certain cases, fair values are not subject to precise quantification or verification and may change as economic and market factors and evaluation of those factors change. Therefore, these estimated fair values are not necessarily indicative of the amounts that would be realized in current market transactions although they do reflect the Bank’s judgment of how a market participant would estimate the fair value. The fair value tables presented below do not represent an estimate of the overall fair value of the Bank as a going concern, which would take into account future business opportunities and the net profitability of assets versus liabilities. The following tables present the carrying values and estimated fair values of the Bank’s financial instruments.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Consolidated obligations are backed only by the financial resources of the FHLBanks. At any time, the Finance Agency may require any FHLBank to make principal or interest payments due on any consolidated obligation, whether or not the primary obligor FHLBank has defaulted on the payment of that obligation. No FHLBank has ever had to assume or pay the consolidated obligation of another FHLBank. The par value of the other FHLBanks’ outstanding consolidated obligations for which the Bank is jointly and severally liable was $996,251 and $885,114 as of March 31, 2020 and December 31, 2019 , respectively, exclusive of the Bank’s own outstanding consolidated obligations. None of the other FHLBanks defaulted on their consolidated obligations, the Finance Agency was not required to allocate any obligation among the FHLBanks, and no amount of the joint and several obligation was fixed as of March 31, 2020 and December 31, 2019 . Accordingly, the Bank has not recognized a liability for its joint and several obligation related to the other FHLBanks’ consolidated obligations as of March 31, 2020 and December 31, 2019 . The following table presents the Bank’s outstanding commitments, which represent off-balance sheet obligations.

(2) Expiration is based on settlement period rather than underlying contractual maturity of consolidated obligations. The carrying value of the guarantees related to standby letters of credit is recorded in “Other liabilities” on the Statements of Condition and amounted to $101 and $117 as of March 31, 2020 and December 31, 2019 , respectively. The Bank is subject to legal proceedings arising in the normal course of business. After consultation with legal counsel, management does not anticipate, as of the date of the financial statements, that the ultimate liability, if any, arising out of these matters will have a material effect on the Bank’s financial condition or results of operations.

Transactions With Shareholders [Abstract]
Transactions With Shareholders	Transactions with Shareholders The Bank is a cooperative whose member institutions own substantially all of the capital stock of the Bank. Former members and certain non-members, which own the Bank’s capital stock as a result of a merger or acquisition of a member of the Bank, own the remaining capital stock to support business transactions still carried on the Bank’s Statements of Condition. All holders of the Bank’s capital stock receive dividends on their investments, to the extent declared by the Bank’s board of directors. All advances are issued to members and eligible housing associates under the Federal Home Loan Bank Act of 1932, as amended (FHLBank Act), and mortgage loans held for portfolio were purchased from members. The Bank also maintains demand deposit accounts primarily to facilitate settlement activities that are related directly to advances and mortgage loans purchased. Transactions with any member that has an officer or director who is also a director of the Bank are subject to the same Bank policies as transactions with other members. Related Parties. In accordance with GAAP, financial statements are required to disclose material related-party transactions other than compensation arrangements, expense allowances, or other similar items that occur in the ordinary course of business. Under GAAP, related parties include owners of more than 10 percent of the voting interests of the Bank. Due to limits on member voting rights under the FHLBank Act and Finance Agency regulations, no member owned more than 10 percent of the total voting interests. Therefore, the Bank had no such related party transactions required to be disclosed for the periods presented. Shareholder Concentrations. The Bank considers shareholder concentration as members or non-members with regulatory capital stock outstanding in excess of 10 percent of the Bank’s total regulatory capital stock. The following tables present transactions with shareholders whose holdings of regulatory capital stock exceeded 10 percent of total regulatory capital stock outstanding.

Accounting Policies [Abstract]
Basis of Accounting [Text Block]	The accompanying unaudited interim financial statements of the Federal Home Loan Bank of Atlanta (Bank) have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). To prepare the financial statements in conformity with GAAP, management must make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements and income and expenses during the reporting period. Actual results could be different from these estimates. The foregoing interim financial statements are unaudited; however, in the opinion of management, all adjustments, consisting only of normal recurring adjustments necessary for a fair statement of the results for the interim periods, have been included. The results of operations for interim periods are not necessarily indicative of results to be expected for the year ending 2020 , or for other interim periods. The unaudited interim financial statements should be read in conjunction with the audited financial statements for the year ended December 31, 2019 , which are contained in the Bank’s 2019 Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC) on March 5, 2020 (Form 10-K). The Bank has certain financial instruments, including derivative instruments and securities purchased under agreements to resell, that are subject to offset under master netting arrangements or by operation of law. Additional information regarding derivative instruments is provided in Note 11 — Derivatives and Hedging Activities to the Bank’s interim financial statements. The Bank does not have any offsetting liabilities related to its securities purchased under agreements to resell for the periods presented. Based on the fair value of the related securities held as collateral, the securities purchased under agreements to resell were fully collateralized for the periods presented. Refer to Note 2 — Summary of Significant Accounting Policies to the Bank’s 2019 audited financial statements for a description of all the Bank’s significant accounting policies. There have been no changes to these policies as of March 31, 2020 , except for policy updates related to new accounting guidance pertaining to the measurement of credit losses on financial instruments which is described below.
Credit Loss, Financial Instrument [Policy Text Block]	Beginning on January 1, 2020, the Bank adopted new accounting guidance pertaining to the measurement of credit losses on financial instruments that requires a financial asset or group of financial assets measured at amortized cost to be presented at the net amount expected to be collected. The new guidance also requires credit losses relating to these financial instruments as well as available-for-sale securities to be recorded through the allowance for credit losses. Key changes as compared to prior accounting guidance are detailed below. Consistent with the modified retrospective method of adoption, the prior period has not been revised to conform to the new basis of accounting. Refer to Note 2 — Summary of Significant Accounting Policies to the Bank’s 2019 audited financial statements for information on the prior accounting treatment. Interest-bearing Deposits, Securities Purchased under Agreements to resell, and Federal Funds Sold . Interest-bearing deposits, securities purchased under agreements to resell, and federal funds sold provide short-term liquidity and are carried at amortized cost. Accrued interest receivable is recorded separately on the Statements of Condition. These investments are generally transacted with counterparties that have received a credit rating of triple-B or greater (investment grade) by a nationally recognized statistical rating organization (NRSRO) including the the following: Standard and Poor’s (S&P), Moody’s Investors Service (Moody’s), and Fitch Ratings. All of these investments were with counterparties rated investment grade as of March 31, 2020. These investments are evaluated quarterly for expected credit losses. If applicable, an allowance for credit losses is recorded with a corresponding credit loss expense (or reversal of credit loss expense). The Bank uses the collateral maintenance provision practical expedient to evaluate potential credit losses related to securities purchased under agreements to resell. Consequently, a credit loss would be recognized if there is a collateral shortfall which the Bank does not believe the counterparty will replenish in accordance with its contractual terms. The credit loss would be limited to the difference between the fair value of the collateral and the investment’s amortized cost. Securities purchased under agreements to resell are short-term and are structured such that they are evaluated regularly to determine if the market value of the underlying securities decreases below the market value required as collateral (i.e. subject to collateral maintenance provisions). If so, the counterparty must place an equivalent amount of additional securities as collateral or remit an equivalent amount of cash, generally by the next business day. The Bank did not have any securities purchased under agreements to resell as of March 31, 2020. Federal funds sold are unsecured loans that are generally transacted on an overnight term. All investments in interest-bearing deposits and federal funds sold were repaid or expected to be repaid according to the contractual terms as of March 31, 2020 and December 31, 2019. No allowance for credit losses was recorded for these assets as of March 31, 2020 and December 31, 2019. The carrying values of interest-bearing deposits excludes accrued interest receivable that was not material as of March 31, 2020 and December 31, 2019. The carrying values of federal funds sold excludes accrued interest receivable of $3 and $10 as of March 31, 2020 and December 31, 2019, respectively. Held-to-maturity Securities . Securities that the Bank has both the ability and intent to hold to maturity are classified as held-to-maturity and carried at amortized cost, which is original cost net of periodic principal repayments and amortization of premiums and accretion of discounts. Accrued interest receivable is recorded separately on the Statements of Condition. Held-to-maturity securities are evaluated quarterly for expected credit losses on a pool basis unless an individual assessment is deemed necessary because the securities do not possess similar risk characteristics. If applicable, an allowance for credit losses is recorded with a corresponding credit loss expense (or reversal of credit loss expense). The allowance for credit losses excludes uncollectible accrued interest receivable, which is measured separately. Prior to January 1, 2020, credit losses were recorded as a direct write-down of the held-to-maturity security carrying value. The Bank’s held-to-maturity securities consist of U.S. agency obligations, government-sponsored enterprise debt obligations, state or local housing agency debt obligations, and MBS issued by the Government National Mortgage Association (Ginnie Mae), the Federal Home Loan Mortgage Corporation (Freddie Mac), and the Federal National Mortgage Association (Fannie Mae) that are backed by single-family or multifamily mortgage loans. The Bank only purchase securities considered investment quality. All of these investments were rated double-A, or above, by a NRSRO as of March 31, 2020, based on the lowest long-term credit rating for each security. The Bank evaluates its held-to-maturity securities for impairment on a collective, or pooled basis unless an individual assessment is deemed necessary because the securities do not possess similar risk characteristics. The Bank has not established an allowance for credit loss on any of its held-to-maturity securities as of March 31, 2020 because the securities: (1) were all highly-rated and/or had short remaining terms to maturity, (2) had not experienced, nor did the Bank expect, any payment default on the instruments, and (3) in the case of U.S., government-sponsored enterprises, or other agency obligations, carry an implicit or explicit government guarantee such that the Bank considers the risk of nonpayment to be zero. Advances . Advances are carried at amortized cost, which is original cost net of periodic principal repayments and amortization of premiums and accretion of discounts (including discounts related to the Affordable Housing Program and Economic Development and Growth Enhancement Program), net deferred fees or costs, and fair value hedge adjustments. Accrued interest receivable is recorded separately on the Statements of Condition. The advances are evaluated quarterly for expected credit losses. If applicable, an allowance for credit losses is recorded with a corresponding credit loss expense (or reversal of credit loss expense). Refer to Note 2 — Summary of Significant Accounting Policies to the Bank’s 2019 audited financial statements for details on the allowance methodologies related to advances. Mortgage Loans Held for Portfolio . Mortgage loans held for portfolio are recorded at amortized cost, which is original cost, net of periodic principal repayments and amortization of premiums and accretion of discounts, fair value hedge adjustments on loans initially classified as mortgage loan commitments, and direct write-downs. Accrued interest receivable is recorded separately on the Statements of Condition. The Bank performs at least quarterly an assessment of its mortgage loans held for portfolio to estimate expected credit losses. If applicable, an allowance for credit losses is recorded with a corresponding credit loss expense (or reversal of credit loss expense). The Bank measures expected credit losses on mortgage loans on a collective basis, pooling loans with similar risk characteristics. If a mortgage loan no longer shares risk characteristics with other loans, it is removed from the pool and evaluated for expected credit losses on an individual basis. When developing the allowance for credit losses, the Bank measures the estimated loss over the remaining life of a mortgage loan, which also considers how the Bank’s credit enhancements mitigate credit losses. If a loan was purchased at a discount, the discount does not offset the allowance for credit losses. The allowance excludes uncollectible accrued interest receivable, as the Bank write-off accrued interest receivable by reversing interest income if a mortgage loan is placed on nonaccrual status. Refer to Note 2 — Summary of Significant Accounting Policies to the Bank’s 2019 audited financial statements for details on the allowance methodologies related to mortgage loans. Off-Balance Sheet Credit Exposures. The Bank evaluates its off-balance sheet credit exposure on a quarterly basis for expected credit losses. If deemed necessary, an allowance for expected credit losses on these off-balance sheet exposures is recorded in other liabilities with a corresponding credit loss expense (or reversal of credit loss expense). The Bank monitors the creditworthiness of its standby letters of credit based on an evaluation of the member. In addition, standby letters of credit are fully collateralized from the time of issuance. The Bank has established parameters for the measurement, review, classification, and monitoring of credit risk related to these standby letters of credit that result in an internal credit rating, which focuses primarily on an institution’s overall financial health and takes into account the quality of assets, earnings, and capital position. In general, borrowers categorized into the highest risk rating category have more restrictions on the types of collateral that they may use to secure standby letters of credit, may be required to maintain higher collateral maintenance levels and deliver loan collateral, and may face more stringent collateral reporting requirements. Based on the Bank’s credit analyses and collateral requirements, the Bank does not deem it necessary to record any additional liability on the Statements of Condition for these commitments as of March 31, 2020.
