U.S. Treasury Yield Nears Yearly High, Should Investors Panic? Market Eyes Key Resistance Line

Rising tensions between the U.S. and Iran have not only pushed up international oil prices but also dampened market optimism about inflation cooling, leading to renewed selling of U.S. Treasury bonds and pushing yields close to their 2024 highs. Since U.S. Treasury yields serve as a benchmark for mortgages, corporate financing, and consumer loans, rising borrowing costs are beginning to weigh on stock market gains.

The 10-year U.S. Treasury yield, a key global financial indicator, reached 4.665% at Wednesday’s close, narrowly missing the 2024 intraday high of 4.687% set on May 19.

The rebound in oil prices has shifted market expectations, rapidly cooling bets on rate cuts. The rise in Treasury yields primarily reflects changing market expectations for the Federal Reserve’s (Fed) policy rates. When investors believe interest rates will remain high or rise further, existing bond prices fall, pushing yields higher.

The main catalyst recently has been the renewed U.S.-Iran conflict, which has driven oil prices higher. Rising energy prices have raised concerns about a resurgence in inflationary pressures, increasing the likelihood of rate hikes rather than cuts.

However, the recent movement in yields hasn’t fully tracked oil prices. Before the U.S.-Iran ceasefire collapsed, oil prices had already retreated to February levels—before the U.S. and Israel attacked Iran—but the 10-year Treasury yield remained near pre-war highs, indicating that market concerns extend beyond energy prices.

Analysts note that before the conflict, markets widely expected the Fed to cut rates this year to avoid an economic downturn. But with U.S. employment data consistently exceeding expectations, the economy’s resilience has become more apparent, causing rate-cut expectations to fade. As a result, yields didn’t decline significantly even when oil prices temporarily fell.

Additionally, the AI investment boom continues to drive data center construction and related demand, seen as a key factor supporting inflation and reinforcing market expectations that a high-rate environment could persist.

Rising borrowing costs are pressuring equity valuations. Higher Treasury yields mean increased government borrowing costs and further upward pressure on corporate bond, mortgage, and other loan rates. As U.S. Treasuries are considered the world’s most creditworthy asset, their financing costs often serve as a benchmark for other borrowers.

Currently, higher interest rates remain a pressure point rather than a crisis. Large tech companies continue issuing bonds to fund AI data center construction, and consumer spending hasn’t shown clear signs of cooling, with steady demand for everything from auto parts to electronics.

Still, rising yields could pressure stocks in two ways: by increasing corporate financing costs and by making bond investments more attractive, potentially shifting funds from equities to fixed-income markets.

U.S. stocks have recently traded in a high-range consolidation pattern. The S&P 500 fell 0.1% on Wednesday and has been mostly flat this month; the Dow Jones Industrial Average closed nearly unchanged, while the Nasdaq Composite dropped 0.6%.

Will U.S. Treasury yields test the 5% psychological barrier again?

The market’s biggest concern is whether the 10-year Treasury yield will break through the 4.687% high set in May. Some analysts warn that breaching this resistance could prompt the market to seek a new equilibrium, potentially accelerating yield gains.

Historically, since the 2008–2009 financial crisis, the 10-year Treasury yield briefly surpassed 5% only in October 2023. That surge triggered stock market volatility, with fears that high rates would drag on economic growth.

Fortunately, the '5%' level proved to be an attractive entry point for buyers. Yields spent less than a morning above 5% before quickly retreating below 4.9%, and ended the year below 4%. This suggests that when yields reach relatively high levels, they often attract renewed inflows into the bond market, providing some support.
