U.S. Bond Market Overview

The U.S. bond market experienced a considerable decline for the 12 months ended October 31, 2022 (the “reporting period”). The Bloomberg U.S. Aggregate Bond Index, a broad measure of U.S. fixed-income performance, returned -15.68%.

The U.S. Federal Reserve’s (Fed’s) shift toward tighter monetary policy was the primary factor driving the market downturn. Annualized consumer price inflation, which had been under 3.0% for over a decade, began to rise throughout 2021 and ultimately climbed above 6.0% in the year’s fourth calendar quarter. The inflation picture soon grew even more challenging following Russia’s invasion of Ukraine in early 2022, which—together with the resulting sanctions—further snarled global supply chains and contributed to a spike in energy prices. Inflation exceeded 8.0% in March 2022 and remained above that level through the end of the reporting period, with a peak of 9.1% in June.

The Fed moved aggressively in an effort to calm price pressures, ending its stimulative quantitative easing program and boosting interest rates from a range of 0.0%-0.25% to 3.0-3.25% in five separate increases from March to September 2022. This marked the largest move in such a short interval since 1980. In addition, the Fed appeared set to continue raising rates until inflation showed signs of returning closer to its longer-term target of 2%. Some evidence began to emerge later in the period that the Fed’s rate hikes had begun to reduce activity in certain segments of the economy, but there was still no sign that consumer price inflation had started to decline in a meaningful fashion. As a result, market prices at the end of October indicated that the central bank would not stop tightening until rates reached the 4.5-5.0% range.

These circumstances weighed heavily on bond market performance. The yield on the two-year U.S. Treasury note rose from 0.50% at the beginning of the period to 4.48% by the end of October 2022, while the 10-year yield climbed from 1.55% to 4.05%. The yield curve inverted significantly as result, meaning that short-term yields were higher those on longer-term debt. In late September, the yield curve moved to its largest inversion since 1982.

The surge in U.S. Treasury yields, together with investors’ increased aversion to risk, fueled weakness across all sectors of the bond market. Mortgage-backed securities, which were hurt by concerns about the housing market and the loss of demand stemming from Fed’s decision to end its quantitative easing policy, posted negative returns. Still, the category held up better than the broader index.

Investment-grade corporate bonds were among the worst-performing segments of the market. In addition to being adversely affected by rising Treasury yields, the asset class was pressured by a pronounced increase in yield spreads. The latter trend reflected concerns that weaker economic growth could lead to a slowdown in corporate earnings. Notably, the yield on corporate bonds—as gauged by the ICE BofA US Corporate Index—closed the period at the highest level since 2009.

High yield bonds also experienced sizable losses. As was the case with investment-grade corporates, a rise in both prevailing yields and yield spreads weighed heavily on performance. However, the category outperformed the investment-grade market due to its lower interest-rate sensitivity and higher weighting in the energy sector. Higher-rated issuers in the category—which are seen as having the least vulnerability to slowing growth—generally outperformed their lower-quality counterparts.

Investment Objective

The iShares 0-5 Year Investment Grade Corporate Bond ETF (the “Fund”) seeks to track the investment results of an index composed of U.S. dollar-denominated, investment-grade corporate bonds with remaining maturities of less than five years, as represented by the Markit iBoxx USD Liquid Investment Grade 0-5 Index (the “Index”). The Fund invests in a representative sample of securities included in the Index that collectively has an investment profile similar to the Index. Due to the use of representative sampling, the Fund may or may not hold all of the securities that are included in the Index.

Portfolio Management Commentary

All major segments of the fixed-income market, including high quality corporate bonds, experienced negative returns over the 12-month period, as hawkish monetary policy and rising Treasury yields weighed on performance.

Entering the period, U.S. inflation was already running well above the 2% target of the U.S. Federal Reserve (Fed). Inflation would spike in the wake of Russia’s late-February invasion of Ukraine, which exacerbated ongoing supply-chain pressures and led to sharply higher commodity prices. Consumer price inflation rose by at least 7.5% on a year-over-year basis in each of the first nine months of 2022, hitting a peak of 9.1% in June. In response, the Fed aggressively raised its benchmark overnight lending rate, bringing the Fed funds target to a range of 3.0% to 3.25%, as compared to 0% to 0.25% at the start of 2022. In addition, the market anticipated significant further rate increases from the Fed in the coming months.

The U.S. Treasury yield curve moved dramatically higher in response to the Fed’s policy tightening, with the two-year yield moving from 0.50% to 4.48% over the 12 months, an increase of 398 basis points. Longer-term Treasury yields, which are less directly influenced by changes in Fed funds, rose to a more moderate degree, as reflected in the bellwether 10-year note yield which increased from 1.55% to 4.05%, or 250 basis points. As a result, short-term Treasury yields were higher than long-term yields at the end of the period, raising concerns that the economy was on the verge of recession.

Returns for investment grade corporate bonds with maturities of five years or less held up better than for their longer-term counterparts but were nonetheless negative for the reporting period, as both rising Treasury yields and widening credit spreads had a negative impact on performance. In terms of credit quality, lower-rated issues in the Moody’s A and Baa rating categories accounted for the great majority of the negative return for the Index, primarily due to their significant weights within the Index. In terms of maturities, more interest rate-sensitive bonds with maturities closest to five years weighed most heavily on performance given the rise in Treasury yields seen during the period.

Returns for corporate bonds rated Aaa to A were notably negative for the reporting period. While A-rated bonds actually slightly outperformed their higher quality counterparts, the segment accounted for the majority of the Index’s negative return due to its heavy weight within the Index. In terms of maturities, more interest rate sensitive bonds with maturities of greater than 10 years weighed most heavily on performance given the rise in Treasury yields seen during the period.

Portfolio Management Commentary

High-yield bonds, including those rated BB, lost considerable ground in the annual period. A surge in inflation prompted the U.S. Federal Reserve (Fed) to tighten monetary policy by winding down its stimulative quantitative easing program and beginning to raise interest rates. The Fed hiked rates by a total of three percentage points over the 12-month period, bringing the benchmark Fed funds rate to a range of 3.0% to 3.25%.

High yield bonds were also pressured by rising spreads relative to U.S. Treasuries. At their peak in early July, spreads stood at their highest level in nearly two years. The spread widening was the result of an increase investor risk aversion that was driven, in part, by Russia’s invasion of Ukraine and elevated volatility in the equity market. In addition, investors became more cautious on corporate credit given the prospect of slowing economic growth and a concurrent downturn in corporate earnings in 2023. High yield bond funds experienced significant outflows as a result, further weighing on prices.

Returns for corporate bonds rated BB or the equivalent were notably negative for the reporting period. However, BB-rated bonds outperformed their higher quality, investment grade counterparts due to their lower interest rate sensitivity in a rising rate environment. That said, within the Index performance was weakest for bonds with maturities of greater than 10 years, followed by the 7-10 year maturity range. From a sector perspective, Financial issuers underperformed while Energy issuers outperformed.

Portfolio Management Commentary

U.S. dollar-denominated convertible bonds experienced significant declines over the reporting period. Convertible bonds are hybrid securities that have features of both debt and equity. The bonds represented in the Index pay interest on a periodic basis, similar to standard corporate bonds, but they also have an equity conversion feature and can be redeemed for shares of the issuer’s stock. Due to their convertibility feature, these securities advance or decline with stocks but with less volatility given their fixed-income component.

Entering the period, U.S. inflation was already running well above the 2% target of the U.S. Federal Reserve (Fed). Inflation would spike in the wake of Russia’s late-February invasion of Ukraine, which exacerbated ongoing supply-chain pressures and led to sharply higher commodity prices.

Convertible securities experienced a sizable downturn beginning late in the first quarter of 2022 and extending into the second quarter, in keeping with the direction across the financial markets. Investor risk sentiment weakened dramatically on tighter Fed policy, recession fears, and the war in Ukraine. Additionally, the prospect of a higher interest rate regime for an extended period weighed on assets with more distant cash flows, such the type of growth company heavily represented in the convertible market. New issue supply of convertibles fell off sharply from the robust levels seen during the post-pandemic rebound, as waning investor demand led to less favorable pricing. As a result, the index returned -24.87% over the reporting period.

Much of the convertible universe is unrated, and unrated issues accounted for the great majority of the Index’s negative return. In sector terms, technology issues are the largest Index constituent and the sector accounted for roughly half of the negative Index return, as rising interest rates weighed on assets with more distant cash flows.

Portfolio Management Commentary

While most segments of the fixed-income market experienced steeply negative returns over the 12-month period against a backdrop of hawkish monetary policy and rising Treasury yields, investment grade floating rate bonds managed to post a small positive return as gauged by the Index.

Entering the period, U.S. inflation was already running well above the 2% target of the U.S. Federal Reserve (Fed). Inflation would spike in the wake of Russia’s late-February invasion of Ukraine, which exacerbated ongoing supply-chain pressures and led to sharply higher commodity prices. Consumer price inflation rose by at least 7.5% on a year-over-year basis in each of the first nine months of 2022, hitting a peak of 9.1% in June.

The U.S. Treasury yield curve moved dramatically higher in response to the Fed’s policy tightening, with the two-year yield moving from 0.50% to 4.48% over the 12 months, an increase of 398 basis points. Longer-term Treasury yields, which are less directly influenced by changes in Fed funds, rose to a more moderate degree, as reflected in the bellwether 10-year note yield which increased from 1.55% to 4.05%, or 250 basis points. As a result, short-term Treasury yields were higher than long-term yields at the end of the period, raising concerns that the economy was on the verge of recession.

The Index principally comprises U.S. dollar-denominated bonds with interest rates that reset periodically. Floating rate bonds are generally attractive to investors in a rising interest-rate environment. Because their coupon rates adjust to reflect shifts in short-term interest rates, their prices are not very sensitive to changing interest rates. That said, prices for floating rate bonds can fluctuate based on changes in the economic outlook and credit sentiment, as a weaker economy can impact the ability of companies to service their debts. Investment-grade floating-rate bonds posted a modest positive performance for the reporting period, as investors were attracted to their relative price stability in a rising interest rate environment.

Portfolio Management Commentary

Green bonds seek to raise funds for projects that aim to positively affect the environment, typically by promoting energy efficiency or reducing carbon emissions. Projects financed using green bonds can include investments in renewable energy generation, wastewater collection and treatment, sustainable forest management, and upgrading equipment to improve energy efficiency.

Effective March 1, 2022, enhancements were made to the iShares Global Green Bond ETF to change its focus from global to U.S. dollar-denominated, investment-grade green bonds. The change is a result of the substantial growth seen in the USD green bond market since the inception of the fund in 2018.

Interest in green bonds continued to grow over the period given the outlook for spending to support efforts to move toward zero carbon emissions and renewable energy sources. In this vein the U.S. Inflation Reduction Act of 2022 included incentives in support of green initiatives.

The Index had a negative return for the period as a sharp rise in U.S. Treasury yields along with an increase in risk aversion on the part of investors given heightened geopolitical uncertainty and recession fears led to weakness across all sectors of the bond market. Investment-grade corporate bonds, which constitute roughly half of the Index, were among the weakest-performing segments of the market. In addition to being adversely affected by rising market interest rates, prices for the asset class were pressured by an increase in credit spreads as investors became concerned that weaker economic growth would lead to a slowdown in corporate earnings. Viewed by credit quality, holdings of bonds rated Baa by Moody’s, the lowest investment grade rating, had the biggest negative impact on return given the widening of credit spreads. In terms of bond maturities, exposure to issues with maturities of 10 years or longer weighed most heavily on return as rates moved higher.

About Fund Performance

Past performance is not an indication of future results. Financial markets have experienced extreme volatility and trading in many instruments has been disrupted. These circumstances may continue for an extended period of time and may continue to affect adversely the value and liquidity of each Fund’s investments. As a result, current performance may be lower or higher than the performance data quoted. Performance data current to the most recent month-end is available at iShares.com. Performance results assume reinvestment of all dividends and capital gain distributions and do not reflect the deduction of taxes that a shareholder would pay on fund distributions or on the redemption or sale of fund shares. The investment return and principal value of shares will vary with changes in market conditions. Shares may be worth more or less than their original cost when they are redeemed or sold in the market. Performance for certain funds may reflect a waiver of a portion of investment advisory fees. Without such a waiver, performance would have been lower.

Net asset value or “NAV” is the value of one share of a fund as calculated in accordance with the standard formula for valuing mutual fund shares. Beginning August 10, 2020, the price used to calculate market return (“Market Price”) is the closing price. Prior to August 10, 2020, Market Price was determined using the midpoint between the highest bid and the lowest ask on the primary stock exchange on which shares of a fund are listed for trading, as of the time that such fund’s NAV is calculated. Since shares of a fund may not trade in the secondary market until after the fund’s inception, for the period from inception to the first day of secondary market trading in shares of the fund, the NAV of the fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike a fund, an index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by a fund. These expenses negatively impact fund performance. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower.

Disclosure of Expenses

Shareholders of each Fund may incur the following charges: (1) transactional expenses, including brokerage commissions on purchases and sales of fund shares and (2) ongoing expenses, including management fees and other fund expenses. The expense examples shown (which are based on a hypothetical investment of $1,000 invested at the beginning of the period and held through the end of the period) are intended to assist shareholders both in calculating expenses based on an investment in each Fund and in comparing these expenses with similar costs of investing in other funds.

The expense examples provide information about actual account values and actual expenses. Annualized expense ratios reflect contractual and voluntary fee waivers, if any. In order to estimate the expenses a shareholder paid during the period covered by this report, shareholders can divide their account value by $1,000 and then multiply the result by the number under the heading entitled “Expenses Paid During the Period.”

The expense examples also provide information about hypothetical account values and hypothetical expenses based on a fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses. In order to assist shareholders in comparing the ongoing expenses of investing in the Funds and other funds, compare the 5% hypothetical examples with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

The expenses shown in the expense examples are intended to highlight shareholders’ ongoing costs only and do not reflect any transactional expenses, such as brokerage commissions and other fees paid on purchases and sales of fund shares. Therefore, the hypothetical examples are useful in comparing ongoing expenses only and will not help shareholders determine the relative total expenses of owning different funds. If these transactional expenses were included, shareholder expenses would have been higher.
