10‑year Treasury yield spikes above 4.7% as Middle East tensions rise

The 10‑year U.S. Treasury yield surged to 4.71% on Thursday, its highest level since January 2025, as oil prices jumped above $100 per barrel following Houthi attacks on tankers in the Red Sea【3】. The move puts the benchmark within striking distance of the psychologically important 5% threshold, a level that could pressure equity valuations.

Yield breakout and market reaction

The yield’s rise follows a sharp oil rally triggered by Houthi rebels striking tankers off Saudi Arabia’s Red Sea coast, pushing Brent crude futures above $100 per barrel【3】. Higher energy prices feed inflation expectations, which in turn lift longer‑dated Treasury yields. The 2‑year note also edged higher to 4.15%, reflecting tighter short‑term rate outlooks. Equity markets responded modestly; the S&P 500 remains about 3% shy of its record, while the dollar firmed against major peers as investors seek safety in the greenback.

Context and forward‑looking concerns

Treasury yields have been elevated this year on concerns over a swelling U.S. fiscal deficit and persistent inflation, but the recent Middle‑East flare‑up adds a new risk premium. The 4.71% level is the first time the 10‑year has breached the May high of 4.7% and sits just below the 5.021% peak briefly seen in October 2023, the last time yields hovered at that mark【3】. Analysts note that a sustained breach of 5% could “hugely negative” equity performance, though the ultimate impact will depend on whether the yield rise is driven by inflationary pressures or productivity gains【3】.

Policy backdrop

The yield spike arrives ahead of the Fed’s May personal consumption expenditures (PCE) price index release, the central bank’s preferred inflation gauge, due Thursday. Core PCE is expected to rise from April, and any surprise upward move could reinforce expectations of higher rates, further supporting yields【1】. The market also watches the Federal Reserve’s two‑day policy meeting starting Tuesday, where the new chair Kevin Warsh is not expected to change the benchmark rate but will signal future policy direction【2】.

What to watch

• May core PCE data (Thursday): an above‑forecast reading could push the 10‑year yield closer to 5%.
• Fed policy meeting (Tuesday‑Wednesday): statements from Chair Warsh may clarify the path for short‑term rates.
• Oil price trajectory: a sustained Brent price above $100 could keep inflation expectations elevated, supporting higher yields.

The 10‑year Treasury’s march toward 5% underscores how geopolitical shocks can quickly translate into higher borrowing costs, raising questions about the resilience of equity markets and the Fed’s ability to anchor inflation expectations.
