The Markets in Review

Dear Shareholder,

Significant economic headwinds emerged during the 12-month reporting period ended February 28, 2023, as investors navigated changing economic conditions and volatile markets. The U.S. economy shrank in the first half of 2022 before returning to modest growth in the second half of the year, marking a shift to a more challenging post-reopening economic environment. Changes in consumer spending patterns and a tight labor market led to elevated inflation, which reached a 40-year high before beginning to moderate. Moreover, while the foremost effect of Russia’s invasion of Ukraine has been a severe humanitarian crisis, the ongoing war continued to present challenges for both investors and policymakers.

Equity prices fell as interest rates rose, particularly during the first half of the reporting period. Both large-and small-capitalization U.S. stocks fell, although equities began to recover in the second half of the period as inflation eased and economic growth resumed. Emerging market stocks and international equities from developed markets declined overall, pressured by rising interest rates and a strong U.S. dollar.

The 10-year U.S. Treasury yield rose notably during the reporting period, driving its price down, as investors reacted to fluctuating inflation data and attempted to anticipate its impact on future interest rate changes. The corporate bond market also faced inflationary headwinds, and higher interest rates led to rising borrowing costs for corporate issuers.

The U.S. Federal Reserve (the “Fed”), acknowledging that inflation has been more persistent than expected, raised interest rates eight times. Furthermore, the Fed wound down its bond-buying programs and accelerated the reduction of its balance sheet.

Restricted labor supply kept inflation elevated even as other inflation drivers, such as goods prices and energy costs, moderated. While economic growth slowed in the last year, we believe that taming inflation requires a more substantial decline that lowers demand to a level more in line with the economy’s productive capacity. Although the Fed has decelerated the pace of interest rate hikes, it still seems determined to get inflation back to target. With this in mind, we believe the possibility of a U.S. recession in the near-term is high, but the dimming economic outlook has not yet been fully reflected in current market prices. We believe investors should expect a period of higher volatility as markets adjust to the new economic reality and policymakers attempt to adapt to rapidly changing conditions. Turmoil in the banking sector shortly following the end of the period highlighted the potential for the knock-on effects of substantially higher interest rates to disrupt markets with little warning.

While we favor an overweight to equities in the long term, several factors lead us to take an underweight stance on equities overall in the near term. Expectations for corporate earnings remain elevated, which seems inconsistent with the possibility of a recession in a business environment characterized by higher costs and reduced pricing power. Nevertheless, we are overweight on emerging market stocks as a weaker U.S. dollar provides a supportive backdrop. We also see long-term opportunities in credit, where valuations are appealing and higher yields provide attractive income, although we are neutral on credit in the near term, as we believe that troubles in the banking sector will likely lead to reduced lending. However, we believe there are still some strong opportunities for a six- to twelve-month horizon, particularly short-term U.S. Treasuries, global inflation-linked bonds, and emerging market bonds denominated in local currency.

Overall, our view is that investors need to think globally, position themselves to be prepared for a decarbonizing economy, and be nimble as market conditions change. We encourage you to talk with your financial advisor and visit iShares.com for further insight about investing in today’s markets.

U.S. Treasury Bond Market Overview

The ICE U.S. Treasury Core Bond Index returned -10.08% for the 12 months ended February 28, 2023 (the “reporting period”), behind the -9.72% return of the Bloomberg U.S. Aggregate Bond Index, a broad measure of U.S. taxable bond performance.

The poor return for the fixed-income market reflected the backdrop of elevated inflation and rising short-term interest rates. Consumer price inflation—which began to rise in late 2021—took another leg higher following Russia’s invasion of Ukraine in early 2022, with year-over-year increases of over 8% in each month from March to September. While inflation showed signs of cooling in late 2022, it nonetheless remained in a range of 6.4% to 7.5% over the final four months of the period – well above the U.S. Federal Reserve’s (Fed’s) stated target of 2%.

The Fed responded to rising inflation by winding down its stimulative quantitative easing program and beginning to raise interest rates aggressively. The Fed boosted short-term rates eight times over the course of the 12-month period, moving the benchmark fed funds rate from a range of 0.0% - 0.25% to 4.5% - 4.75%. This represented the fastest increase in such a short span of time in decades. In addition, the Fed’s communications repeatedly stated the central bank’s intent to remain steadfast in its commitment to fighting inflation. This approach quashed periodic hopes for a pivot toward a less restrictive policy, and it prompted investors to ratchet up their expectations for the likely “terminal rate;” in other words, the level at which the Fed could stop raising rates. The continued strength of the economy, along with ongoing tightness in the labor market, further fueled expectations that rates would stay “higher for longer.”

These circumstances created significant headwinds for the U.S. Treasury market. The yield on the two-year note rose from 1.43% to 4.82% (as its price fell) over the course of the year, while the 10-year yield climbed from 1.83% to 3.92%. As a result of these moves, the yield curve reached its highest level of inversion (in other words, the extent to which short-term rates exceed longer-term rates) since 1981. Notably, the Treasury market posted its second consecutive calendar year with a negative return in 2022. This marked the first time this had occurred since 1958-59.

Longer-dated bonds were the weakest performers on a total return basis, with the largest losses occurring among issues with maturities of ten years and above. On the other hand, those with maturities in the zero- to three-year range outpaced the broader market.

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.
