The U.S. bond market is under pressure. Investors are selling government debt, pushing yields higher, as inflation climbs and energy prices keep rising.
The US bond market crisis is intensifying.
While everyone is focused on AI and the Iran War, the US bond market is in a complete meltdown.

The 30-year Treasury bond yield crossed 5% on Tuesday morning. That happened after a fresh inflation reading showed consumer prices rose 3.8% year-over-year in April — the highest rate in three years.
Bond prices and yields move in opposite directions. When investors sell bonds, yields rise.
Energy costs are a big driver of the inflation spike. Gas prices now average $4.50 a gallon nationally, according to AAA. Diesel prices near record highs are pushing up the cost of goods transported by truck and rail.
Global Brent crude climbed above $107 a barrel on Tuesday. That marks a 77% increase so far this year, according to FactSet.
The Iran war is keeping oil prices elevated. President Trump recently rejected an offer from Tehran to end the conflict. With the summer travel season approaching, relief at the pump looks unlikely in the near term.
Why Bond Investors Are Watching Oil
Tom di Galoma, managing director at Mischler Financial Group, said the oil market is key. “It all depends on what oil does in the next two to three weeks,” he said. “The fact that oil continues to push higher, people don’t find a really good reason to buy long bonds.”
Higher inflation erodes the value of bonds’ fixed payments. It can also push central banks to raise interest rates, which weighs on both stocks and bonds.
The 10-year Treasury yield is now approaching 4.50%. That level is being watched closely — it was the point that triggered Trump’s 90-day tariff pause back in April 2025.
Long-term yields have now risen above where they were before the Federal Reserve started cutting rates. This shows the Fed has limited control over the long end of the yield curve.
What This Means for Mortgages and Debt
If yields keep rising, U.S. mortgage rates could climb back above 7%. That would put further strain on homebuyers and the housing market.
The U.S. federal debt now stands at roughly $30 trillion. More than half of that is set to mature in the next three years, according to a Wells Fargo Investment Institute report.
The deficit is expected to add another $5 trillion to $6 trillion to that debt load over the same period if covered by more Treasury issuance.
The Treasury Department is also set to auction $42 billion in 10-year notes and $25 billion in 30-year bonds this week. That new supply adds to the pressure on yields.
Fed-fund futures show roughly even odds of a rate hike by March 2027, per the CME FedWatch Tool. Josh Jamner of ClearBridge Investments said rate cuts in 2027 are still more likely than hikes, provided the Iran conflict eases and labor markets stay soft.
In the past, institutional investors have stepped in to buy bonds when the 30-year yield hits 5%. Whether that happens this time depends largely on what oil prices do next.
