U.S. Treasury yields edged higher Monday after U.S. and Israeli strikes on Iran over the weekend escalated tensions in the Middle East, complicating the traditional safe-haven calculus for bond investors.
At 6:03 a.m. ET, the benchmark 10-year Treasury yield rose 1 basis point to 3.972%, while the 30-year bond added nearly 1 basis point to 4.639%. The 2-year Treasury note climbed more sharply, up more than 3 basis points to 3.412%. One basis point equals 0.01 percentage point, and yields move inversely to prices.
The modest increase in yields indicates a market balancing two opposing forces. On one side is geopolitical risk, which typically drives investors into Treasuries, pushing prices up and yields lower. On the other is the prospect of higher oil prices and renewed inflation pressure, which can push yields higher by eroding real returns and reshaping expectations for Federal Reserve policy.

U.S. and Israeli strikes killed Iran’s Supreme Leader, Ayatollah Ali Khamenei, and more than 200 people in Iran, according to state media. Iran retaliated with attacks on U.S. bases in the Middle East, killing three American service members and seriously wounding five others. President Donald Trump told CNBC’s Joe Kernen that U.S. military operations are “ahead of schedule” and warned the conflict could last up to four weeks, with further American casualties expected.
Yield curve dynamics and policy expectations
The sharper rise in the 2-year yield — the maturity most sensitive to monetary policy — suggests traders are reassessing the near-term path of interest rates. If oil prices surge and remain elevated, headline inflation could reaccelerate, complicating the Federal Reserve’s policy outlook.
Higher energy costs feed quickly into transportation and production expenses and can lift consumer price indices, particularly if shipping insurance premiums and freight rates rise. In such a scenario, policymakers may be forced to delay rate cuts or signal a more cautious easing trajectory.
The 10-year and 30-year yields, which incorporate longer-term growth and inflation expectations as well as term premiums, rose only modestly. That pattern points to a market not yet pricing in a severe or prolonged supply shock. If investors were anticipating a sustained conflict with structural energy disruption, long-end yields could move more decisively.
Another factor is the U.S. fiscal backdrop. Potential supplemental defense spending or emergency appropriations linked to Middle East operations could widen the federal deficit, increasing Treasury issuance. Greater supply can exert upward pressure on yields, particularly at longer maturities, if demand does not keep pace.
Analysis: Oil, inflation expectations, and global spillovers
Energy markets are central to the bond outlook. The Gulf region plays a pivotal role in global crude exports. Any disruption to production, refining, or maritime transit could amplify price volatility. Even in the absence of physical supply damage, risk premiums embedded in crude futures can raise inflation expectations.
Breakeven inflation rates — derived from Treasury Inflation-Protected Securities — will be closely monitored for signs that investors expect higher consumer prices over the medium term. A sustained rise in breakevens would indicate growing concern that energy shocks are seeping into core inflation.
At the same time, geopolitical crises can dampen growth through reduced trade, weaker business confidence, and tighter financial conditions. If the conflict drags on and weighs on global activity, recession risks could resurface, potentially reasserting downward pressure on longer-dated yields.
This tension between inflation risk and growth risk often produces choppier bond trading and curve volatility. A steepening yield curve could signal inflation anxiety, while a flattening curve might point to recession fears dominating.
Data calendar adds to volatility risk
Investors are also preparing for a consequential week of economic data. February’s jobs report, January retail sales, and February unemployment figures are due Friday, offering insight into labor market resilience and consumer strength. Earlier in the week, the ISM manufacturing report and ADP employment data will provide additional signals on economic momentum.
Stronger-than-expected data could reinforce upward pressure on short-term yields if markets conclude that the Fed has less room to ease. Conversely, softer readings could revive demand for longer-duration bonds, particularly if geopolitical uncertainty intensifies.
Currently, Treasury markets appear to be in a wait-and-see mode. The incremental rise in yields suggests investors are not yet rushing aggressively into safe-haven assets, nor are they fully pricing a sustained inflation shock. The next decisive move will likely lie on the trajectory of oil prices, the duration of military operations, and incoming economic data.
In effect, the bond market is serving as a barometer of whether the current escalation remains a contained geopolitical event or evolves into a broader macroeconomic shock with lasting implications for inflation, growth, and U.S. fiscal policy.
