Nature of Banking Activities and Significant Accounting Policies [Abstract]
Nature of Banking Activities and Significant Accounting Policies	Note 1. Nature of Banking Activities and Significant Accounting Policies Organization Community Bankers Trust Corporation (the “Company”) is headquartered in Richmond, Virginia and is the holding company for Essex Bank (the “Bank”), a Virginia state bank with 24 full-service offices, 18 of which are in Virginia and six of which are in Maryland. The Bank also operates two loan production offices. The Bank engages in a general commercial banking business and provides a wide range of financial services primarily to individuals, small businesses and larger commercial companies, including individual and commercial demand and time deposit accounts, commercial and industrial loans, consumer and small business loans, real estate and mortgage loans, investment services, on-line and mobile banking products, and cash management services. Financial Statements The consolidated statements presented include accounts of the Company and the Bank, its wholly-owned subsidiary. All material intercompany balances and transactions have been eliminated. The statements should be read in conjunction with the Company’s consolidated financial statements and the accompanying notes to consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. The accounting and reporting policies of the Company conform to U.S. generally accepted accounting principles (GAAP) and to the general practices within the banking industry. The interim financial statements have not been audited; however, in the opinion of management, all adjustments, consisting of normal accruals, were made that are necessary to present fairly the balance sheet of the Company as of March 31, 2021, the statements of income, comprehensive income, changes in shareholders’ equity and cash flows for the three months ended March 31, 2021. Results for the three month period ended March 31, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. The financial information contained within the statements is, to a significant extent, financial information that is based on measures of the financial effects of transactions and events that have already occurred. A variety of factors could affect the ultimate value that is obtained when either earning income, recognizing an expense, recovering an asset or relieving a liability. The Company uses historical loss factors as one factor in determining the inherent loss that may be present in its loan portfolio. Actual losses could differ significantly from the historical factors that the Company uses. In addition, GAAP itself may change from one previously acceptable method to another method. Although the economics of the Company’s transactions would be the same, the timing of events that would impact its transactions could change. In preparing these financial statements, the Company has evaluated subsequent events and transactions for potential recognition or disclosure through the date the financial statements were issued. ​ ​ ​ ​

Gains and losses on securities transactions are determined using the specific identification method. Gross realized gains and losses on securities transactions during the three months ended March 31, 2021 and 2020 were as follows (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2021 March 31, 2020 ​ Gross realized gains ​ $ 16 ​ $ 29 ​ Gross realized losses ​ — ​ (68) ​ Net securities gain ​ $ 16 ​ $ (39) ​ ​ In estimating other than temporary impairment (OTTI) losses, management considers the length of time and the extent to which the fair value has been less than cost, the financial condition and short-term prospects for the issuer, and the intent and ability of management to hold its investment for a period of time to allow a recovery in fair value. There were no investments held that had OTTI losses for the three months ended March 31, 2021 and 2020. The fair value and gross unrealized losses for securities, segregated by the length of time that individual securities have been in a continuous gross unrealized loss position, at March 31, 2021 and December 31, 2020 were as follows (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2021 ​ ​ Less than 12 Months ​ 12 Months or More ​ Total ​ Fair Value Unrealized Loss Fair Value Unrealized Loss Fair Value Unrealized Loss Securities Available for Sale ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Treasury securities ​ $ 7,804 ​ ​ (1) ​ $ — ​ $ — ​ $ 7,804 ​ ​ (1) U.S. Government agencies ​ ​ 14,300 ​ ​ (69) ​ ​ 5,069 ​ ​ (106) ​ ​ 19,369 ​ ​ (175) State, county and municipal ​ 28,045 ​ ​ (1,094) ​ ​ 417 ​ ​ (33) ​ ​ 28,462 ​ ​ (1,127) Mortgage backed securities ​ 9,175 ​ ​ (173) ​ ​ — ​ ​ — ​ ​ 9,175 ​ ​ (173) Asset backed securities ​ 19,093 ​ ​ (61) ​ ​ 532 ​ ​ (3) ​ ​ 19,625 ​ ​ (64) Corporate bonds ​ 5,251 ​ ​ (90) ​ — — ​ ​ — ​ ​ 5,251 ​ ​ (90) Total ​ $ 83,668 ​ $ (1,488) ​ $ 6,018 ​ $ (142) ​ $ 89,686 ​ $ (1,630) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ ​ Less than 12 Months ​ 12 Months or More ​ Total ​ Fair Value Unrealized Loss Fair Value Unrealized Loss Fair Value Unrealized Loss Securities Available for Sale ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Treasury securities ​ $ 23,499 ​ $ (1) ​ $ — ​ $ — ​ $ 23,499 ​ $ (1) U.S. Government agencies ​ 6,726 ​ ​ (25) ​ ​ 8,266 ​ ​ (116) ​ ​ 14,992 ​ ​ (141) State, county and municipal ​ 6,203 ​ ​ (49) ​ ​ 301 ​ ​ (15) ​ ​ 6,504 ​ ​ (64) Mortgage backed securities ​ 118 ​ ​ (1) ​ ​ — ​ ​ — ​ ​ 118 ​ ​ (1) Asset backed securities ​ 12,427 ​ ​ (8) ​ ​ 4,410 ​ ​ (49) ​ ​ 16,837 ​ ​ (57) Corporate bonds ​ 7,216 ​ ​ (18) ​ ​ — ​ ​ — ​ ​ 7,216 ​ ​ (18) Total ​ $ 56,189 ​ $ (102) ​ $ 12,977 ​ $ (180) ​ $ 69,166 ​ $ (282) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The unrealized losses (impairments) in the investment portfolio at March 31, 2021 and December 31, 2020 are generally a result of market fluctuations of interest rates that occur daily. The unrealized losses are from 87 securities at March 31, 2021. Of those, 73 are investment grade, have U.S. government agency guarantees, or are backed by the full faith and credit of local municipalities throughout the United States. Seven investment grade asset-backed securities comprised of student loan pools, which are 97% U.S. government guaranteed, included in corporate obligations and seven corporate bonds make up the remaining securities with unrealized losses at March 31, 2021. The Company considers the reason for impairment, length of impairment, and ability and intent to hold until the full value is recovered in determining if the impairment is temporary in nature. Based on this analysis, the Company has determined these impairments to be temporary in nature. The Company does not intend to sell, and it is more likely than not that the Company will not be required to sell, these securities until they recover in value or reach maturity. Market prices are affected by conditions beyond the control of the Company. Investment decisions are made by the management group of the Company and reflect the overall liquidity and strategic asset/liability objectives of the Company. Management analyzes the securities portfolio frequently and manages the portfolio to provide an overall positive impact to the Company’s income statement and balance sheet. Securities with amortized costs of $52.5 million and $52.2 million at March 31, 2021 and December 31, 2020, respectively, were pledged to secure public deposits as required or permitted by law. Securities with amortized costs of $4.7 million and $5.0 million at March 31, 2021 and December 31, 2020, respectively, were pledged to secure lines of credit at the Federal Reserve discount window. At each of March 31, 2021 and December 31, 2020, there were no securities purchased from a single issuer, other than U.S. Treasury securities and other U.S. Government agencies that comprised more than 10% of the consolidated shareholders’ equity.

Loans and Related Allowance for Loan Losses The Company’s loans, net of deferred fees and costs, at March 31, 2021 and December 31, 2020 were comprised of the following (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2021 ​ December 31, 2020 ​ Amount ​ % of Loans ​ Amount ​ % of Loans Mortgage loans on real estate: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Residential 1‑4 family ​ $ 184,286 15.32 % $ 197,228 16.68 % Commercial ​ 504,846 41.98 ​ 474,856 40.16 ​ Construction and land development ​ 161,825 13.45 ​ 182,277 15.42 ​ Second mortgages ​ 6,526 0.54 ​ 6,360 0.54 ​ Multifamily ​ 87,624 7.29 ​ 78,158 6.61 ​ Agriculture ​ 7,947 0.66 ​ 6,662 0.56 ​ Total real estate loans ​ 953,054 79.24 ​ 945,541 79.97 ​ Commercial loans ​ 239,782 19.94 ​ 225,386 19.06 ​ Consumer installment loans ​ 8,595 0.71 ​ 9,996 0.85 ​ All other loans ​ 1,292 0.11 ​ 1,439 0.12 ​ Total loans ​ $ 1,202,723 100.00 % $ 1,182,362 100.00 % ​ The Company held $10.6 million and $10.7 million in balances of loans guaranteed by the United States Department of Agriculture (USDA), which are included in various categories in the table above, at March 31, 2021 and December 31, 2020, respectively. As these loans are 100% guaranteed by the USDA, no loan loss allowance is required. These loan balances included a purchase premium of $776,000 and $804,000 million at March 31, 2021 and December 31, 2020, respectively. The purchase premium is amortized as an adjustment of the related loan yield on a straight line basis, which is substantially equivalent to the results obtained using the effective interest method. Any unamortized purchase premium remaining on loans prepaid by the borrower is written off. The Company originated loans under the Paycheck Protection Program (PPP) of the Small Business Administration (SBA). These PPP loans totaled $67.7 million and $49.3 million at March 31, 2021 and December 31, 2020, respectively, and are included in commercial loans. As these loans are 100% guaranteed by the SBA, no loan loss allowance is required. The majority of the PPP loans have a five year term; however, most are expected to be forgiven by the SBA as borrowers use the funds for qualified expenses. These loan balances included net fees of $2.3 million and $920,000 at March 31, 2021 and December 31, 2020, respectively, which are being amortized as an adjustment of the related loan yield on a straight line basis, which is substantially equivalent to the results obtained using the effective interest method. Any unamortized net fee remaining on loans forgiven or prepaid by the borrower is recorded as income. At March 31, 2021 and December 31, 2020, the Company’s allowance for loan losses was comprised of the following: (i) a specific valuation component calculated in accordance with the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 310, Receivables, with FASB ASC 450, Contingencies The following table summarizes information related to impaired loans at and for the three months ended March 31, 2021 (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ ​ ​ March 31, 2021 ​ March 31, 2021 ​ ​ ​ ​ Unpaid ​ ​ ​ ​ ​ ​ ​ ​ ​ Recorded ​ Principal ​ Related ​ Average ​ Interest ​ ​ ​ Investment (1) ​ Balance (2) ​ Allowance ​ Investment ​ Recognized ​ With no related allowance recorded: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Mortgage loans on real estate: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Residential 1‑4 family ​ $ 308 ​ $ 412 ​ $ — ​ $ 466 ​ $ 3 ​ Commercial ​ 3,421 ​ 4,174 ​ — ​ 3,002 ​ 33 ​ Total real estate loans ​ 3,729 ​ 4,586 ​ — ​ 3,468 ​ 36 ​ Subtotal impaired loans with no valuation allowance ​ 3,729 ​ 4,586 ​ — ​ 3,468 ​ 36 ​ With an allowance recorded: ​ ​ ​ ​ ​ ​ Mortgage loans on real estate: ​ ​ ​ ​ ​ ​ Residential 1‑4 family ​ 2,253 ​ 2,645 ​ 660 ​ 2,226 ​ 11 ​ Commercial ​ 191 ​ 582 ​ 55 ​ 196 ​ — ​ Construction and land development ​ 5 ​ 113 ​ 2 ​ 25 ​ — ​ Agriculture ​ 45 ​ 47 ​ 13 ​ 45 ​ — ​ Total real estate loans ​ 2,494 ​ 3,387 ​ 730 ​ 2,492 ​ 11 ​ Commercial loans ​ 1,462 ​ 1,474 ​ 385 ​ 2,005 ​ 1 ​ Consumer installment loans ​ 12 ​ 12 ​ 3 ​ 15 ​ — ​ Subtotal impaired loans with a valuation allowance ​ 3,968 ​ 4,873 ​ 1,118 ​ 4,512 ​ 12 ​ Total: ​ ​ ​ ​ ​ ​ Mortgage loans on real estate: ​ ​ ​ ​ ​ ​ Residential 1‑4 family ​ 2,561 ​ 3,057 ​ 660 ​ 2,692 ​ 14 ​ Commercial ​ 3,612 ​ 4,756 ​ 55 ​ 3,198 ​ 33 ​ Construction and land development ​ 5 ​ 113 ​ 2 ​ 25 ​ — ​ Agriculture ​ 45 ​ 47 ​ 13 ​ 45 ​ — ​ Total real estate loans ​ 6,223 ​ 7,973 ​ 730 ​ 5,960 ​ 47 ​ Commercial loans ​ 1,462 ​ 1,474 ​ 385 ​ 2,005 ​ 1 ​ Consumer installment loans ​ 12 ​ 12 ​ 3 ​ 15 ​ — ​ Total impaired loans ​ $ 7,697 ​ $ 9,459 ​ $ 1,118 ​ $ 7,980 ​ $ 48 ​ (1) The amount of the investment in a loan is not net of a valuation allowance, but does reflect any direct write-down of the investment.

A reconciliation of impaired loans to nonaccrual loans at March 31, 2021 and December 31, 2020, is set forth in the table below (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2021 December 31, 2020 Nonaccruals ​ $ 3,496 ​ $ 4,460 Trouble debt restructure and still accruing ​ 4,201 ​ 4,679 Total impaired ​ $ 7,697 ​ $ 9,139 ​ Interest income on nonaccrual loans, if recognized, is recorded using the cash basis method of accounting. There was $103,000 in cash basis income recognized during the three months ended March 31, 2021. There was an insignificant amount of cash basis income recognized during the three months ended March 31, 2020. For the three months ended March 31, 2021 and 2020, estimated interest income of $50,000 and $97,000, respectively, would have been recorded if all such loans had been accruing interest according to their original contractual terms.

The subsequent recovery of loan loss provision for the three months ended March 31, 2021 reflected a more stable economic climate in the first quarter of 2021 compared with each quarter in 2020. This is evidenced by the level of charge-offs and delinquencies, which have remained relatively low. Also, the majority of loans that were granted COVID-19 related payment relief have resumed normal payments. The allowance for loan losses could be further impacted by COVID-19; however, the amount of that impact is not currently estimable.

Fair Values of Assets and Liabilities [Abstract]
Fair Values of Assets and Liabilities	Note 8. Fair Values of Assets and Liabilities FASB ASC 820, Fair Value Measurements and Disclosures, ● Level 1 — Valuation is based upon quoted prices for identical instruments traded in active markets. ● Level 2 — Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities. ● Level 3 — Valuation is determined using model-based techniques with significant assumptions not observable in the market. These unobservable assumptions reflect the Company ’ s own estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include the use of third party pricing services, option pricing models, discounted cash flow models and similar techniques. FASB ASC 825, Financial Instruments Assets and Liabilities Recorded at Fair Value on a Recurring Basis The Company utilizes fair value measurements to record adjustments to certain assets to determine fair value disclosures. Securities available for sale and the cash flow hedge are recorded at fair value on a recurring basis. The tables below present the recorded amount of assets and liabilities measured at fair value on a recurring basis as of March 31, 2021 and December 31, 2020 (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2021 ​ Total Level 1 Level 2 Level 3 Investment securities available for sale ​ ​ ​ ​ U.S. Treasury securities ​ $ 7,804 ​ $ 7,804 ​ $ — ​ $ — U.S. Government agencies ​ 36,123 ​ ​ 9,326 ​ ​ 26,797 ​ — State, county and municipal ​ 124,611 ​ ​ 4,574 ​ ​ 120,037 ​ — Mortgage backed securities ​ 32,274 ​ ​ — ​ ​ 32,274 ​ — Asset backed securities ​ 46,712 ​ ​ 4,596 ​ ​ 42,116 ​ — Corporate bonds ​ 25,602 ​ ​ — ​ ​ 25,602 ​ — Total investment securities available for sale ​ 273,126 ​ ​ 26,300 ​ ​ 246,826 ​ — Total assets at fair value ​ $ 273,126 ​ $ 26,300 ​ $ 246,826 ​ $ — Cash flow hedge liability ​ $ 449 ​ — ​ $ 449 ​ — Total liabilities at fair value ​ $ 449 ​ $ — ​ $ 449 ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ Total Level 1 Level 2 Level 3 Investment securities available for sale ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Treasury securities ​ $ 23,499 ​ $ 23,499 ​ $ — ​ $ — U.S. Government agencies ​ ​ 25,853 ​ 4,034 ​ 21,819 ​ — State, county and municipal ​ 125,720 ​ 5,945 ​ 119,775 ​ — Mortgage backed securities ​ 32,189 ​ 5,534 ​ 26,655 ​ — Asset backed securities ​ 37,488 ​ 9,784 ​ 27,704 ​ — Corporate bonds ​ 26,598 ​ 500 ​ 26,098 ​ — Total investment securities available for sale ​ 271,347 ​ 49,296 ​ 222,051 ​ — Total assets at fair value ​ $ 271,347 ​ $ 49,296 ​ $ 222,051 ​ $ — Cash flow hedge liability ​ ​ 631 ​ — ​ $ 631 ​ — Total liabilities at fair value ​ $ 631 ​ $ — ​ $ 631 ​ $ — ​ Investment securities available for sale Investment securities available for sale are recorded at fair value each reporting period. Fair value measurement is based upon quoted prices, if available (Level 1). If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions (Level 2). The Company utilizes a third party vendor to provide fair value data for purposes of determining the fair value of its available for sale securities portfolio. The third party vendor uses reputable pricing companies for security market data. The third party vendor has controls in place for month-to-month market checks and zero pricing, and a Statement on Standards for Attestation Engagements No. 18 report is obtained from the third party vendor on an annual basis. The Company makes no adjustments to the pricing service data received for its securities available for sale. Cash flow hedge The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis The Company is also required to measure and recognize certain other financial assets at fair value on a nonrecurring basis on the consolidated balance sheet. The following tables present assets measured at fair value on a nonrecurring basis as of March 31, 2021 and December 31, 2020 (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2021 ​ Total Level 1 Level 2 Level 3 Impaired loans ​ $ 2,409 ​ $ — ​ $ — ​ $ 2,409 Bank premises and equipment held for sale ​ 1,507 ​ — ​ — ​ 1,507 Other real estate owned ​ 4,313 ​ — ​ — ​ 4,313 Total assets at fair value ​ $ 8,229 ​ $ — ​ $ — ​ $ 8,229 Total liabilities at fair value ​ $ — ​ $ — ​ $ — ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ Total Level 1 Level 2 Level 3 Impaired loans ​ $ 3,449 ​ $ — ​ $ — ​ $ 3,449 Bank premises and equipment held for sale ​ ​ 1,507 ​ ​ — ​ ​ — ​ 1,507 Other real estate owned ​ 4,361 ​ — ​ — ​ 4,361 Total assets at fair value ​ $ 9,317 ​ $ — ​ $ — ​ $ 9,317 Total liabilities at fair value ​ $ — ​ $ — ​ $ — ​ $ — ​ Impaired loans Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. Once a loan is identified as individually impaired, management measures the impairment in accordance with FASB ASC 310, Receivables Impaired loans can also be evaluated for impairment using the present value of expected future cash flows discounted at the loan’s effective interest rate. The measurement of impaired loans using future cash flows discounted at the loan’s effective interest rate rather than the market rate of interest is not a fair value measurement and is therefore excluded from fair value disclosure requirements. Reviews of classified loans are performed by management on a quarterly basis. Bank premises and equipment held for sale The fair value of bank premises and equipment held for sale was determined using the adjusted appraisal methodology described in the other real estate owned (OREO) asset section below. Other real estate owned OREO assets are adjusted to fair value less estimated disposal costs upon transfer of the related loans to OREO, establishing a new cost basis. Initial fair value is based on appraised values of the collateral less estimated disposal costs. Subsequent to the transfer, valuations are periodically performed by management based on updated appraisals, general market conditions, recent sales of similar properties, length of time the properties have been held, and the Company’s ability and intent with regard to continued ownership of the properties. The assets are carried at the lower of carrying value or fair value less estimated disposal costs ranging from 2% to 10%. The Company may incur additional write-downs of OREO assets to fair value less estimated costs to sell if valuations indicate a further deterioration in market conditions. As such, the Company records OREO as a nonrecurring fair value measurement classified as Level 3. ​ Fair Value of Financial Instruments FASB ASC 825, Financial Instruments The following reflects the fair value of financial instruments, whether or not recognized on the consolidated balance sheet, at fair value measures by level of valuation assumptions used for those assets.

Cash Flow Hedge	Note 11. Cash Flow Hedge The Company designates derivatives as cash flow hedges when they are used to manage exposure to variability in cash flows related to forecasted transactions on variable rate borrowings, such as FHLB borrowings, repurchase agreements, and brokered CDs. The Company had interest rate swaps designated as cash flow hedges with a total notional amount of $20 million at each of March 31, 2021 and December 31, 2020. The swaps were entered into with a counterparty that met the Company’s credit standards, and the agreements contain collateral provisions protecting the at-risk party. The Company believes that the credit risk inherent in the contracts is not significant. The Company had $770,000 of cash pledged as collateral at each of March 31, 2021 and December 31, 2020. Amounts receivable or payable are recognized as accrued under the terms of the agreements. In accordance with FASB ASC 815, Derivatives and Hedging

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Note 12. Revenue Recognition The Company recognizes income in accordance with FASB ASU 2014-09, Revenue from Contracts with Customers (Topic 606), Service charges and fees on deposit accounts The Company earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer’s account balance. Interchange and ATM fees The Company earns interchange and ATM fees from debit/credit cardholder transactions conducted through the Visa and ATM payment networks. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. Because the Company acts as an agent and does not control the services rendered to the customers, related costs are netted against the fee income. These costs were included in other operating expenses prior to the adoption of Topic 606. Brokerage fees and commissions Brokerage fees and commissions consist of other recurring revenue streams such as commissions from sales of mutual funds and other investments to customers by a third-party service provider and investment advisor fees. The Company receives commissions from the third-party service provider on a monthly basis based upon customer activity for the month. The investment advisor fees are charged to the customer’s account in advance on the first month of the quarter, and the revenue is recognized over the following three-month period. The following table presents noninterest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the three months ended March 31, 2021 and 2020 (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ ​ ​ March 31, 2021 ​ March 31, 2020 ​ Noninterest income ​ ​ ​ ​ ​ ​ ​ In-scope of Topic 606: ​ ​ ​ ​ ​ ​ ​ Service charges and fees on deposit accounts ​ $ 318 ​ $ 454 ​ Interchange and ATM fees ​ 361 ​ 218 ​ Brokerage fees and commissions ​ 98 ​ 72 ​ Noninterest income (in-scope of Topic 606) ​ 777 ​ 744 ​ Noninterest income (out-of-scope of Topic 606) ​ 851 ​ 591 ​ Total noninterest income ​ $ 1,628 ​ $ 1,335 ​ ​

Nature of Banking Activities and Significant Accounting Policies [Abstract]
Organization	Organization Community Bankers Trust Corporation (the “Company”) is headquartered in Richmond, Virginia and is the holding company for Essex Bank (the “Bank”), a Virginia state bank with 24 full-service offices, 18 of which are in Virginia and six of which are in Maryland. The Bank also operates two loan production offices. The Bank engages in a general commercial banking business and provides a wide range of financial services primarily to individuals, small businesses and larger commercial companies, including individual and commercial demand and time deposit accounts, commercial and industrial loans, consumer and small business loans, real estate and mortgage loans, investment services, on-line and mobile banking products, and cash management services.
Financial Statements	Financial Statements The consolidated statements presented include accounts of the Company and the Bank, its wholly-owned subsidiary. All material intercompany balances and transactions have been eliminated. The statements should be read in conjunction with the Company’s consolidated financial statements and the accompanying notes to consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. The accounting and reporting policies of the Company conform to U.S. generally accepted accounting principles (GAAP) and to the general practices within the banking industry. The interim financial statements have not been audited; however, in the opinion of management, all adjustments, consisting of normal accruals, were made that are necessary to present fairly the balance sheet of the Company as of March 31, 2021, the statements of income, comprehensive income, changes in shareholders’ equity and cash flows for the three months ended March 31, 2021. Results for the three month period ended March 31, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. The financial information contained within the statements is, to a significant extent, financial information that is based on measures of the financial effects of transactions and events that have already occurred. A variety of factors could affect the ultimate value that is obtained when either earning income, recognizing an expense, recovering an asset or relieving a liability. The Company uses historical loss factors as one factor in determining the inherent loss that may be present in its loan portfolio. Actual losses could differ significantly from the historical factors that the Company uses. In addition, GAAP itself may change from one previously acceptable method to another method. Although the economics of the Company’s transactions would be the same, the timing of events that would impact its transactions could change. In preparing these financial statements, the Company has evaluated subsequent events and transactions for potential recognition or disclosure through the date the financial statements were issued.
