Indian government bonds plummeted early on Tuesday, as fresh strikes in the Gulf obstructed shipping through the Strait of Hormuz, yanking oil higher and triggering a global debt selloff. U.S.-Iran fighting stretched into a third night after a fragile ceasefire collapsed, with both sides reinstating rival blockades of the strait once again. Brent crude climbed 9.6% overnight, its biggest jump in more than six years, and added 1.9% in Asian trade to be at $84.84 per barrel.
