Stalled U.S.-Iran talks have kept oil prices volatile and pushed U.S. Treasury yields close to recent multi-year highs, although yields remain slightly below those levels. Negotiators are pressing Iran for concessions on its nuclear program to restart ceasefire discussions, while U.S. President Trump had previously rejected an Iranian ceasefire proposal. Tradeweb data showed the two-year Treasury yield up 4.4 basis points to 4.907%, the 10-year yield up 2.8 basis points to 5.208%, and the 30-year yield up 1.7 basis points to 5.518%. Tensions around the Hormuz Strait have added to oil-market uncertainty despite increasing crude exports from Saudi Arabia and the UAE. Reopening the strait could allow Gulf producers to increase exports further.
