Why are US bond yields rising? Is it the Iran war or a stronger economy?
Rising Treasury Yields Spark Debate Over Energy Shock and Economic Strength
Indiadailyupdate.com – Long-term US Treasury yields are climbing as investors weigh two competing explanations: the inflationary effect of the Iran conflict and evidence that the American economy remains more resilient than expected. The distinction matters well beyond bond markets, since Treasury yields influence borrowing costs for mortgages, businesses, consumers and the federal government.
US Treasury Secretary Scott Bessent has argued that the latest rise in yields is mainly a temporary consequence of higher energy prices. In his view, the conflict involving Iran has created an oil-driven shock that has lifted headline inflation, but has not fundamentally changed the underlying path of price pressures.
Bessent Sees Temporary Inflation Pressure
Bessent said headline inflation is running at roughly 3.5%, while core inflation—which excludes food and energy categories—is closer to 2.3%. That gap is central to his argument. Energy costs can move sharply in response to geopolitical events, and their effect can spread through transport, heating and many everyday goods.
He expects inflation to cool when the conflict ends and energy prices retreat. If that happens, he believes longer-dated Treasury yields could also decline, potentially moving back toward the levels seen in mid-February before the conflict began. Lower yields would also be relevant for households because mortgage rates often move in the same general direction as long-term government borrowing costs.
Bessent has not offered a timetable for the end of the conflict. Still, he maintains that the current energy-related pressure should not be treated as a permanent feature of the inflation outlook or interest-rate environment.
Private-Sector Hiring Supports the Optimistic View
The Treasury secretary also points to employment trends as evidence of an improving economy. About 1 million private-sector jobs have been added this year, while government payrolls have declined by approximately 300,000 positions. Bessent considers the shift toward private hiring important because sustained private-sector employment can support income growth and broader economic activity.
His assessment is that the economy is only beginning to show stronger momentum. A firmer growth outlook can itself push Treasury yields higher, as investors may demand greater returns when they expect growth to stay solid and interest rates to remain elevated for longer.
That creates a complicated picture for markets. The same yield increase can reflect concern about inflation, confidence in growth, expectations about future Federal Reserve policy, or a combination of all three. The disagreement is therefore not simply about whether yields are rising, but about what investors believe is driving the move.
Economists Warn That Pay Is Not Keeping Pace
Other economists are less convinced that households are experiencing the kind of wage strength implied by the broader growth narrative. Gregory Daco, chief economist at EY, said average hourly earnings rose at a 3% annualized pace in September, the weakest rate of the post-pandemic period.
Daco expects the September Consumer Price Index to show inflation near 3.6%. If consumer prices rise faster than wages, workers lose purchasing power even when their paychecks increase in dollar terms. He projects that inflation-adjusted wages could decline by 0.6% from a year earlier.
Such an outcome would extend the run of falling real wages to six consecutive months. Real wages are a useful measure for households because they show what earnings can actually buy after accounting for inflation. When this measure weakens, consumers may become more cautious about discretionary purchases, travel, large household items and other spending decisions.
Stock-market gains are still providing some support to overall consumer spending, but Daco believes income pressure could curb the pace of spending growth as the economy moves toward 2027. Consumer demand is especially important in the United States because household spending is a major part of overall economic activity.
Pressure on Purchasing Power Could Slow Growth
Joe Brusuelas, chief economist at RSM, also sees signs that the economy strengthened in the third quarter. However, he does not believe inflation has eased sufficiently to remove the strain on household budgets. Higher prices, particularly for energy, can reduce the practical value of wage gains and limit the ability of consumers to spend.
Brusuelas expects the upcoming CPI figures to show that real wage growth has been flat or below zero since the Iran conflict began. He believes the reduction in purchasing power could become a modest drag on economic growth during the final quarter of 2026 and the opening months of 2027.
This concern highlights why energy prices receive so much attention. More expensive oil and fuel do not affect only drivers at the gasoline pump. They can raise costs for freight, manufacturing, aviation and logistics, which may then filter into prices paid by consumers. At the same time, higher household energy bills leave less money available for other purchases.
Federal Reserve Officials Focus on Economic Resilience
Federal Reserve officials have emphasized a different side of the yield story. Fed Chairman Kevin Warsh has described economic strength as the principal force behind higher long-term Treasury yields. Under that view, investors are responding less to a short-lived oil shock and more to expectations that growth will remain durable.
Cleveland Fed President Beth Hammack has also pointed to solid recent growth figures, stronger-than-expected corporate earnings and healthy profits. Those developments can encourage markets to price in a longer period of economic expansion, which tends to raise expectations for future interest rates and Treasury yields.
Philadelphia Fed President Anna Paulson has similarly described the economy as resilient, with momentum continuing despite tariffs and higher oil prices. The debate now turns on whether that resilience can persist while inflation remains above the level policymakers would prefer.
For borrowers, the outcome will be felt in financing costs. If Bessent’s view proves correct and energy prices fall after the conflict, Treasury yields and mortgage rates could ease. If growth remains robust and inflation stays sticky, yields may remain higher for longer. The next inflation and wage data will offer an important test of which interpretation is gaining the stronger footing.
