Factors Affecting Performance [Text Block] | How did the Fund perform last year? For the reporting period ended October 31, 2024, the Fund returned 7.10%. For the same period, the Bloomberg U.S. Universal Index returned 11.20% and the Bloomberg U.S. 1-3 Year Government/Credit Bond Index returned 6.25%. What contributed to performance? During the reporting period, the largest contributors to the Fund’s performance were allocations to asset-backed securities, primarily auto and student loans. Also contributing positively to performance was an allocation to investment grade credit, specifically the banking sector. Additionally, commercial mortgage-backed securities, collateralized loan obligations, non-agency mortgages, U.S. high-yield credit, and agency residential mortgage-back securities allocations were additive. The Fund’s duration and curve positioning also contributed positively to performance. (Duration is a measure of a bond's interest rate risk, or how sensitive a bond's price is to changes in interest rates.) What detracted from performance? During the reporting period, there were no significant detractors from the Fund’s returns. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions.

For the same period, the ICE BofA US Broad Market Index returned 10.55% and the ICE ® ® What contributed to performance? During the reporting period, duration and curve positioning contributed to the Fund’s return, supported by the expected path of the U.S. Federal Reserve Bank’s monetary policy and the commencement of the easing cycle. (Duration is a measure of a bond's interest rate risk, or how sensitive a bond's price is to changes in interest rates.) Sector allocation positively contributed to the Fund’s performance, particularly among financial bonds which were supported by the prospect of lower interest rates. Commercial paper, high credit quality investment-grade bonds (rated Aa by Moody’s), and certificates of deposit also contributed to the Fund’s return during the reporting period. What detracted from performance? During the reporting period, the Fund’s maximum average maturity of 180 days, which is shorter than the benchmarks average maturity, detracted from the Fund’s return.

Factors Affecting Performance [Text Block] | How did the Fund perform last year? For the reporting period ended October 31, 2024, the Fund returned 9.91%. For the same period, the Bloomberg U.S. Universal Index returned 11.20% and the BlackRock Interest Rate Hedged Corporate Bond Index returned 9.58%. What contributed to performance? Bond returns were supported by an environment of slowing pricing pressures and steady growth in the United States during the reporting period. Expectations for interest rate cuts grew, and those hopes were realized in September 2024 when the U.S. Federal Reserve lowered short-term interest rates by a 50 basis point cut, its first-rate reduction since March 2020. In anticipation of rate cuts, the yield curve (the difference between a shorter-term bond and a longer-term bond, most often gauged by the 2-year Treasury note and the 10-year Treasury note) steepened during the reporting period. Bond yields and prices move in opposite directions. What detracted from performance? The yield on the 10-year Treasury decreased from 4.93% to 4.28% during the reporting period, leading the Fund’s hedged interest rate positions to detract from performance.

Factors Affecting Performance [Text Block] | How did the Fund perform last year? For the reporting period ended October 31, 2024, the Fund returned -2.74%. For the same period, the S&P Total Market Index returned 37.99% and the S&P GSCI Dynamic Roll (USD) Total Return Index returned -2.49%. What contributed to performance? Amid worries about growth prospects, the European Central Bank cut rates three times, while the United States economy stayed strong, prompting the U.S. Federal Reserve Bank to wait until September before decreasing short-term interest rates for the first since 2020. In contrast, Japan ended its negative interest rate regime and raised rates. Exposure via futures to commodities, such as gold and cocoa, had the largest positive impact on the Fund’s performance during the reporting period. Gold futures rose amid inflationary concerns and geopolitical tensions, while weather conditions were the biggest factor supporting cocoa futures. What detracted from performance? Exposure to natural gas and corn via futures had the largest negative impact on the Fund’s return during the reporting period. Amid high storage levels and abundant supplies, natural gas prices have trended lower. Corn prices were also under pressure from poor supply-demand dynamics.

Factors Affecting Performance [Text Block] | How did the Fund perform last year? For the reporting period ended October 31, 2024, the Fund returned 13.14%. For the same period, the Bloomberg U.S. Universal Index returned 11.20% and the BlackRock Inflation Hedged Corporate Bond Index returned 12.70%. What contributed to performance? Bond returns were supported by an environment of slowing pricing pressures and steady growth in the United States during the reporting period. Inflation measures in the United States trended lower toward the Central Banks’s 2% target, leading the U.S. Federal Reserve’s to lower short-term interest rates by a 50 basis point cut, its first rate reduction since March 2020. What detracted from performance? The Fund uses zero coupon swaps (no cash flows exchange hands until maturity) across multiple points across the curve. If inflation runs below the fixed rate on the consumer price index (CPI) swaps, the swaps will be ‘out of the money’ and this will flow through to the NAV. During the reporting period, lower-than-expected inflation readings, as measured by the CPI, weighed on the Fund’s return.

Factors Affecting Performance [Text Block] | How did the Fund perform last year? For the reporting period ended October 31, 2024, the Fund returned 0.17%. For the same period, the MSCI All Country World Index returned 32.79% and the Bloomberg Roll Select Commodity Total Return Index returned 0.65%. What contributed to performance? The Fund’s exposure to gold was the largest positive performance driver for the reporting period. The period was marked by economic uncertainty, including concerns over a potential recession and fluctuating bond yields. High real yields and a strong U.S. dollar initially pressured gold, but subsequent economic uncertainty and market volatility supported its rise. Central bank purchase activity and interest rate decisions also pushed gold prices higher. Ongoing geopolitical tensions in the Middle East and Russia, as well as global trade and currency shifts, continue to encourage gold buying and restrain gold selling. What detracted from performance? Exposure to natural gas was the largest detractor from performance during the reporting period. Unseasonably warm weather in the U.S. during the winter months reduced heating demand, leading to lower prices. High levels of natural gas production, coupled with fluctuating demand, created volatility in the market. Facility maintenance and pipeline disruptions also influenced supply levels. Geopolitical tensions had mixed impacts on natural gas prices as some events led to temporary price spikes due to fears of supply disruptions, other events had limited long-term effects.

Factors Affecting Performance [Text Block] | How did the Fund perform last year? For the reporting period ended October 31, 2024, the Fund returned 1.92%. For the same period, the ICE BofA US Broad Market Index returned 10.55% and the ICE BofA Commodity Enhanced Carry Total Return Index returned 2.43%. What contributed to performance? During the reporting period, the Fund benefited from exposure via futures to copper. Prices of the metal surged due to increased demand from the renewable energy sector and electric vehicles, coupled with supply disruptions in major copper production countries. Renewed industrial activity and investment in green technology were also contributors. Futures exposure to brent crude oil prices experienced notable fluctuations, influenced by factors including global oil production levels, geopolitical events, and market sentiment. The performance of these futures was characterized by periods of both backwardation and contango, indicating shifts in market supply and demand dynamics. (Contango describes an upward-sloping curve where the prices for future delivery are higher than the spot price, while Backwardation describes a downward-sloping curve where the prices for future delivery are lower than the spot price.) What detracted from performance? During the reporting period there were no significant detractors from the Fund’s return.

Factors Affecting Performance [Text Block] | How did the Fund perform last year? For the reporting period ended October 31, 2024, the Fund returned 9.29%. For the same period, the Bloomberg U.S. Universal Index returned 11.20% and the BlackRock Inflation Hedged U.S. Aggregate Bond Index returned 9.18%. What contributed to performance? Bond returns were supported by an environment of slowing pricing pressures and steady growth in the United States during the reporting period. Inflation measures in the United States trended lower toward the U.S. Federal Reserve Bank’s 2% target, leading the U.S. Federal Reserve to lower short-term interest rates by a 50 basis point cut, its first-rate reduction since March 2020. What detracted from performance? The Fund uses zero coupon swaps (no cash flows exchange hands until maturity) across multiple points across the curve. If inflation runs below the fixed rate on the consumer price index (CPI) swaps, the swaps will be ‘out of the money’ and this will flow through to the NAV. During the reporting period, lower-than-expected inflation readings, as measured by the CPI, weighed on the Fund’s return.

Factors Affecting Performance [Text Block] | How did the Fund perform last year? For the reporting period ended October 31, 2024, the Fund returned 7.10%. For the same period, the Bloomberg U.S. Universal Index returned 11.20% and the BlackRock Interest Rate Hedged U.S. Aggregate Bond Index returned 6.95%. What contributed to performance? Bond returns were supported by an environment of slowing pricing pressures and steady growth in the United States during the reporting period. Expectations for interest rate cuts grew, and those hopes were realized in September 2024 when the U.S. Federal Reserve lowered short-term interest rates by a 50 basis point cut, its first-rate reduction since March 2020. In anticipation of rate cuts, the yield curve (the difference between a shorter-term bond and a longer-term bond, most often gauged by the 2-year Treasury note and the 10-year Treasury note) steepened during the reporting period. The two-year U.S. Treasury note fell from 5.09% to 4.17%, while the ten-year Treasury decreased from 4.93% to 4.28% during the reporting period. (Bond yields and prices move in opposite directions.) What detracted from performance? As the yield on the 10-year Treasury declined during the reporting period, the Fund’s hedged interest rate positions detracted from performance. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions.

Factors Affecting Performance [Text Block] | How did the Fund perform last year? For the reporting period ended October 31, 2024, the Fund returned 19.36%. For the same period, the ICE BofA US Broad Market Index returned 10.55% and the ICE Clean Energy Transition Metals Index returned 20.02%. What contributed to performance? Commodity futures in silver, copper, and aluminum were the largest contributors to the Fund’s performance during the reporting period. Amid worries about growth prospects, the European Central Bank cut rates three times, while the United States economy stayed strong, prompting the U.S. Federal Reserve Bank to wait until September before decreasing short-term interest rates for the first since 2020. Exposure to copper and aluminum via futures benefited from both interest rate cuts and from China’s efforts to stimulate their lagging economy during the reporting period. Silver futures were driven higher as inflation remained elevated in certain regions. What detracted from performance? Exposure to nickel futures had the largest negative impact on the Fund’s performance during the reporting period. Nickel is a major component for low carbon technologies; however, the metal suffered from oversupply and weak demand, particularly from China.
