U.S. Treasury returns have surged in recent days as worries about inflation are fueled by the Iran war, potentially raising the price of borrowing for everything from mortgages and credit cards to car loans.
The yields on bonds with a 30-year term – the annual payment to a bond owner – reached their highest level since 2007. The yields on 10-year Treasuries reached a high of approximately 4.69% on Tuesday, an increase of about 0.75 percentage points from the commencement of the war on Feb. 28.
The yield on 10-year Treasuries decreased on Wednesday, coming in at 4.58%. Nevertheless, yields are higher than the level reached during a bond offloading following President Donald Trump’s “Liberation Day” tariffs in April 2025.
Because bonds provide investors with a consistent fixed payment annually, the possibility of inflation poses a danger of increased consumer costs that would diminish those yearly distributions. In this instance, a worldwide oil crisis has increased energy costs, which has subsequently affected other expenses like food.
Therefore, bonds have become less desirable. When there is a reduction in demand, bond yields increase.
“It’s mainly about the Iran war and its impact on inflation,” Ted Rossman, a senior industry analyst at Bankrate, told ABC News.
High bond yields increase the expense of borrowing for average citizens because Treasury rates have an effect on the rates offered by financial institutions.
Interest payments for mortgages, credit cards, auto loans, and almost any other type of borrowing are largely determined by long-term Treasury yields, Patrice Carrington, a real estate professor at New York University, told ABC News.
Carrington added that the reason for the surge in borrowing costs is that regulated lenders must maintain reserve assets, which frequently consist partly of U.S. Treasuries. The costs incurred by banks that hold Treasuries on their balance sheets increase when Treasury yields rise. Lenders, in turn, address those added expenses by raising borrowing rates.
“The bank will transfer that increased cost of capital to any consumer loan,” Carrington stated.

The housing market, where the average interest rate for a 30-year fixed mortgage is 6.72% as of Monday, according to Mortgage News Daily data, serves as an example of this suffering for consumers. Mortgage rates have gone up by 0.75 percentage points from pre-war levels.
“That is a significant jump,” Rossman stated.
According to Rocket Mortgage, each percentage-point rise in a mortgage rate could result in thousands or tens of thousands of dollars in extra costs each year, depending on the price of the property.
Credit card rates, in contrast, have remained stable during the Iran war, albeit at elevated levels, Rossman stated.
Bankrate data indicated that the average credit card interest rate is 19.57%, which is only slightly lower than it was before the war started. At the beginning of 2026, futures markets anticipated that the Fed would probably lower interest rates at least once before the end of the year, which would lower credit card rates.

However, as the Fed deals with a new wave of inflation, markets estimate there is about a 50% chance that interest rates will stay the same over the course of the year and a 37% chance that rates will be raised, according to the CME FedWatch Tool, a gauge of market opinion. The likelihood of a rate cut this year is estimated by markets to be less than 2%.
As a consequence, credit card rates are “staying higher for longer” than many people thought, according to Rossman.
Analysts had differing viewpoints on recommendations for consumers considering whether to proceed with obtaining a loan immediately or wait for a potential drop in interest rates.
Liu Lu, a professor at the Wharton School at the University of Pennsylvania, stated that mortgage rates are unlikely to significantly decline in the short term, suggesting that borrowers who can afford a loan at the current rates might as well proceed.
“I wouldn’t depend on trying to find the best moment,” Lu told ABC News.
Carrington, in contrast, advised those looking for loans to have patience.
According to Carrington, the economy will eventually weaken, and the Fed will lower interest rates, which will lower borrowing costs.
“We are far beyond schedule for an economic decline,” Carrington stated. “I absolutely think borrowers should wait.”
Meanwhile, the effects of rising bond yields on consumers are not entirely unfavorable. The pattern indicates higher returns for investors who put their money into financial tools like money market funds or high-interest savings accounts, which are usually safer investments than the stock market.
