NYSE A global sell-off of government bonds gripped markets Tuesday morning, sending borrowing costs to multi-decade highs, as hopes for an end to hostilities it the Middle East rapidly faded. It comes after a window for a new deal to be reached between the U.S. and Iran closed without a breakthrough, reigniting concerns about inflationary pressure. On Monday, U.S. President Donald Trump ruled out extending a ceasefire between Washington and Tehran, while Iran issued fresh threats of military escalation. Both sides have rejected further peace talks. Overnight , a cargo vessel was struck by a projectile as it transited the Strait of Hormuz — a waterway that acts as a critical shipping route for global trade and has become a key sticking point in negotiations. The effective closure of the strait throughout the nearly six-month war has seen the cost of energy and other vital commodities rise. Oil prices extended their rally on Tuesday, with global benchmark Brent crude oil futures hovering above the $90-a-barrel mark. At 4:16 a.m. ET, yields on U.S. 30-year Treasurys were up almost 2 basis points to 5.3275%, the highest level since 2002.

But he added: "Rising long-dated bond yields are not driven solely by expectations of higher interest rates and inflation fears. They can also reflect concerns around high levels of government borrowing and investors demanding greater compensation for the risks of holding long-dated government bonds." Deutsche Bank's Jim Reid said in a note that there hadn't been a single catalyst for the declines in the bond market over the past 24 hours, "but with few signs of the US and Iran coming to any sort of a deal, that meant investors priced in a more extended closure of the Strait of Hormuz." "Investors are pricing in a more protracted period of higher oil prices again," he said. "As investor concern mounted about a longer closure for the Strait of Hormuz, that put pressure on fixed income, particularly longer-dated sovereign bonds."
