U.S. Treasury Yields Climb Amid Mixed Signals on U.S.-Iran Negotiations

Treasury Market Moves and Auction Weakness

Treasuries declined on Thursday, pushing yields higher across the curve. The benchmark 10-year Treasury yield was more than 4 basis points higher at 4.3679%. The 30-year Treasury bond yield rose by more than 2 basis points to 4.926%, while the 2-year Treasury note yield increased by more than 5 basis points to 3.937%. One basis point equals 0.01%, and yields move inversely to prices.

The upward move in yields accelerated after the U.S. bond market recorded its second disappointing auction of the week. On Wednesday, the Treasury’s $70 billion 5-year note auction followed a weak $69 billion 2-year auction on Tuesday, which saw its lowest demand since March 2025. The subdued auction results added pressure on prices, contributing to the rise in yields.

Despite a relatively quiet week for U.S. economic data, traders are expected to monitor weekly initial jobless claims data on Thursday afternoon for further indications of underlying economic conditions.

Conflicting Signals on U.S.-Iran Contacts

Global markets have been contending with contradictory statements from Washington and Tehran over the last 48 hours regarding the status of peace-related discussions. U.S. officials have said that negotiations over a proposed peace plan have been taking place. Iran, however, has denied any direct talks with Washington.

Iranian Foreign Minister Abbas Araghchi reportedly told state media on Wednesday that Iranian officials were reviewing an American proposal to end the war, while stressing that Tehran had no intention of entering into negotiations with the United States. He stated that the exchange of messages between the two countries through mediators “does not mean negotiations with the U.S.,” according to Reuters.

Iranian state media also reported on Wednesday that the Islamic Republic would reject a U.S. ceasefire offer and instead put forward its own five-point proposal. That plan would grant Tehran control over the Strait of Hormuz, a strategic maritime chokepoint for global oil shipments. The conflicting communications and Iran’s reported counterproposal have added to uncertainty in global markets and formed part of the backdrop for movements in U.S. government bond yields.
