According to online reports, JPMorgan Chase CEO Jamie Dimon said he expected a "chaos" in the U.S. bond market, prompting the Federal Reserve to intervene. "There will be some chaos in the U.S. bond market due to various rules and regulations," Dimon said in an earnings call on Friday. He added that the Fed would step in at that time, but not until "when they start to panic a little." Yields, especially on long-term bonds, have climbed sharply this week as Trump's tariff policy series sparked broader market turmoil. The move raises questions about whether the asset has lost its safe-haven appeal and raises concerns about a wide unwinding of basis trading.
