U.S. government borrowing costs have moved into territory rarely seen this century, putting long-duration bond ETFs under pressure while restoring levels of fixed-income income that investors have not seen for years.
The 30-year Treasury yield reached 5.48% on September 24, its highest level since 2004, as a global sovereign-bond sell-off intensified. The move reflected concerns that inflation, government borrowing and resilient growth could keep long-term rates elevated.
The sell-off has pushed much of the longer end of the U.S. Treasury curve toward or above 5%. That creates an unusual combination for bond investors: weaker prices for existing long-duration holdings, but substantially higher starting yields for capital entering fixed income today.
Why Yields Are Rising
Monetary policy remains part of the pressure. On September 16, the Federal Reserve raised the federal funds target range by 25 basis points to 3.75% to 4.00%, citing inflation that remains elevated.
Government borrowing adds another force. The U.S. Treasury expects to issue $739 billion of privately held net marketable debt during the July-to-September quarter, followed by another $628 billion in the fourth quarter.
That supply comes against a large fiscal deficit. The Congressional Budget Office projects a $1.9 trillion federal deficit in fiscal 2026, equal to 5.8% of GDP.
Investors are therefore being asked to absorb substantial Treasury issuance while demanding greater compensation for inflation and the risks attached to longer maturities.
BlackRock Says Income Has Returned to Bonds
The same rise in yields hurting bond prices has materially changed the income available from fixed income.
BlackRock Investment Institute said in its August 2026 fixed-income research that more than 80% of the global bond universe was yielding above 4% as of July 31, based on LSEG data. Its strategic portfolio carried an average yield of 5.6%, up from 2.3% five years earlier.
BlackRock's argument is centered on starting income rather than a blanket call to own bonds. The firm says higher global government yields have restored income as a larger source of portfolio returns, while warning that long-term government bonds have become less dependable as portfolio ballast.
That distinction is increasingly visible in BlackRock's own iShares ETF range.
As of September 23, the iShares 0-3 Month Treasury Bond ETF (SGOV) offered a 30-day SEC yield of 3.66% with an effective duration of just 0.11 years. The iShares 1-3 Year Treasury Bond ETF (SHY) yielded 4.41% with a duration of 1.79 years. Moving further out, IEF and TLT offered higher income but materially greater sensitivity to rate moves.
Treasury ETFs Show the Duration Trade-Off
The iShares 20+ Year Treasury Bond ETF (TLT) is the clearest example of the price risk attached to long-duration income.
As of September 24, TLT's 30-day SEC yield had risen to 5.41%, but its NAV total return was -6.15% year to date. Its effective duration was close to 15 years, meaning further increases in long-term rates can produce sizable price declines.
The iShares 7-10 Year Treasury Bond ETF (IEF) offers a middle ground. As of September 22, its 30-day SEC yield was 4.73%, with an effective duration of 6.89 years and a YTD NAV return of -2.64%.
The comparison shows why headline yields alone tell only part of the story. Investors can earn more by extending maturity, but they also assume more interest-rate risk.
GCC Investors Have Local Sukuk ETF Alternatives
For Gulf investors, fixed-income exposure does not have to come through U.S.-listed Treasury ETFs.
The Saudi Exchange lists two Shariah-compliant sukuk ETFs that provide local-market access to Saudi sovereign debt.
The Albilad Saudi Sovereign Sukuk ETF (9403) tracks the Albilad IdealRatings Saudi Sovereign Sukuk Index, which includes Saudi riyal-denominated government sukuk listed on Tadawul with at least three months remaining to maturity. As of September 10, the fund had SAR56.5 million in assets and 6.8 million units outstanding. It has also made several cash distributions during 2026, including SAR0.0644 per unit in August and SAR0.0251 in September.
The larger Alinma Saudi Government Sukuk ETF (9404) held approximately SAR424 million in assets in September. Its June 30 financial statements reported SAR428.4 million in net assets, and the fund invests passively in a basket of Shariah-approved Saudi government sukuk listed on the main market.
What 5% Treasuries Mean for GCC Investors
For GCC investors, the shift in U.S. rates affects both sides of the fixed-income market.
Dollar pegs transmit U.S. monetary conditions into much of the Gulf, while Treasury yields around 5% raise the reference return against which sukuk and regional corporate bonds compete for capital. At the same time, locally listed sukuk ETFs give investors a way to stay within Shariah-compliant structures and avoid some of the domicile and access considerations attached to U.S.-listed funds.
SGOV and SHY prioritize low duration, IEF and TLT introduce progressively greater sensitivity to rates, while Saudi sukuk ETFs add local-currency sovereign exposure and Shariah screening.
BlackRock's research explains why fixed income is drawing renewed attention: yields are higher across much of the global bond market than they were five years ago. The ETF market now gives investors several ways to express that view, but the choice of maturity, domicile and structure can matter as much as the yield itself.
