Europe's central bankers fear more turbulence in testy U.S. relations
SPY•Swap lines seen as a possible target
Another of the Europeans' worries was that political meddling could eventually involve the dollar liquidity backstops provided by the Fed to the world's biggest central banks, considered a cornerstone of global financial stability, some of the sources said.
These swap lines ensure that commercial banks around the world retain their access to U.S. dollars, especially in moments of financial stress.
The Fed renews this facility year after year on the premise that it actually safeguards U.S. interests and markets, since overseas banks in moments of global market upheaval could otherwise be forced to dump U.S. bonds.
"But rationality doesn't always prevail with this administration," a third source said. "When they run retaliatory trade policies with their closest allies, Trump could just say, 'Hey, they're ripping us off' and the swap lines could be gone overnight."
