(Bloomberg) -- Treasuries rose as the latest signs of an accord to end the US-Iran war sent benchmark oil prices to their lowest levels in more than a month, offering potential relief from sustained high inflation.
Yields across maturities reached their lowest levels in more than a week before rebounding to little-changed levels. The 30-year bond's yield, which has closed above 5% every day since May 12, approached 4.98% at one point.
Those levels were reached as oil prices fell after Iranian state television said an unofficial draft US-Iran memorandum of understanding would allow restored commercial transit shipping through the Strait of Hormuz. US attacks in late February disrupted Middle East oil supplies, igniting a price surge that has fueled inflation globally. Central banks including the Federal Reserve are expected to raise interest rates in response.

The Fed's preferred inflation gauge — the personal consumption expenditures price index — is due Thursday. The PCE price index rose 3.5% from a year earlier in March, and economists anticipate an increase to 3.8% in April. The Fed aims for a long-run rate of 2%.
US benchmark West Texas Intermediate crude oil futures fell below $88 a barrel, and global benchmark Brent crude breached $95, both for the first time since April 22.
Treasury yields have broadly declined alongside oil prices since May 19 amid reports of progress toward ending the conflict, even as hostilities continued. However the May yield highs included the highest 30-year yield since 2007, while shorter maturities reached the highest levels in more than a year.
Higher yields may attract investors to Treasury auctions, including a $70 billion sale of five-year notes at 1 p.m. New York time. A two-year note auction on Tuesday drew good demand despite a rally into the bidding deadline that trimmed its yield by about five basis points. The 4.071% auction result was the highest since February 2025.
