Analysts were focused early Monday on weekend comments from Kevin Hassett, National Economic Council director, saying President Donald Trump was "studying" whether he can remove

Federal Reserve Chair Jerome Powell before the end of Powell's term next year. "The topic drives investment away from US assets on the margins, but long-term yields will soar if

the market perceives a real risk to the Fed’s credibility, not rise a few basis points," Will Compernolle, macro strategist at FHN Financial, wrote in a Monday client note. Signs of

slowing inbound goods to the U.S. also were in focus, with high-frequency data from Flexport showing 50% fewer ocean freight bookings from China since tariffs were announced, he wrote.
