The G-20 finance ministers’ gathering in Asheville, North Carolina, ended amid a global bond-market selloff, tariff disputes, public insults and disagreement over a group photograph. U.S. Treasury Secretary Scott Bessent said the meetings were productive and focused on trade imbalances, artificial intelligence and sovereign debt. The tensions raised investor concerns that global officials were not fully addressing risks that could escalate rapidly. By the summit’s close Tuesday, the benchmark 10-year Treasury yield had climbed to 4.795%, its highest level since President Trump began his second term.
