U.S. Treasury yields soar after Donald Trump says Iran ceasefire is ‘over’

U.S. Treasury yields surged on Wednesday after U.S. President Donald Trump told the NATO summit in Turkey that he thinks the ceasefire with Iran is over.

The yield on the 10-year Treasury note — the main benchmark for mortgages, auto loans and credit card debt — was last seen more than 5 basis points higher at 4.5812%.

Shorter- and longer-term yields also moved higher. The yield on the 2-year Treasury note, which typically tracks short-term Federal Reserve interest rate decisions, was up by more than 5 basis points at 4.2182%.

Meanwhile, the 30-year Treasury yield, which traditionally moves on geopolitical events, also jumped more than 3 basis points to 5.0752%.

One basis point equals 0.01%, or 1/100th of 1%, and yields and prices move inversely to one another.

Trump's comments also pushed energy costs higher.

Brent crude futures, the international price benchmark, jumped 6.18% to $78.73 per barrel. U.S. West Texas Intermediate futures were 6.45% higher at $74.93.

Government bond yields finished Tuesday's session higher, with 30-year Treasury yields trading above the key 5% level, and the 10-year note surging more than 6 basis points.

As traders gauge how Trump's comments are likely to shape borrowing costs longer term, they are also awaiting the Federal Open Market Committee's June meeting minutes, published later Wednesday, for more monetary policy insights under new Fed chair Kevin Warsh.

Separately, the Mortgage Bankers Association's latest weekly average 30-year fixed rate — a key barometer of U.S. housing affordability — is due out later. The average 30-year fixed mortgage rate for loans up to $806,500 fell slightly to 6.57% from 6.59% for the week ending July 1.
