In 'normal' times, the ECB cutting rates and signaling it is ready to potentially cut them much further might be expected to be the driving force in world markets that day. The International Monetary Fund warning of a "notable markdown" in global growth might also have come across investors' radar.
But with the Trump administration triggering a global trade war and seemingly bent on upending the global economic order of the past 80 years, these are not normal times. What next, Trump firing Powell or forcing him out?
Nobody knows. But one thing is certain - Trump raised the stakes on Thursday to a whole new level, first in a social media post on his Truth Social platform and later speaking to reporters at the White House.
Powell and his colleagues face an unenviable dilemma, one which is a direct consequence of Trump's tariffs - the slowing economy calls for rates to be cut, but rising inflationary pressures might require them to be raised.
Trump clearly wants lower rates, but Powell said on Wednesday the Fed will continue its 'wait and see' approach before acting one way or the other.
The immediate market impact of Trump's latest attack on Powell - and by extension, attack on the Fed's independence - was to erase the dollar's and Wall Street's gains, and keep long-term Treasury yields at their highs for the day.
Looking ahead, if this crisis deepens investors are likely to view it as the latest in a lengthening list of reasons not to hold U.S. assets. That points to lower stocks, a weaker dollar, and higher Treasury yields.
Long-dated yields are already marching higher and the 'term premium' is its highest in a decade. Faith in the dollar and Treasuries, confidence in U.S. economic policy, and trust in U.S. institutions and governance have rarely been lower.
Fed independence and the prospect, remote or otherwise, of a new Trump-appointed Fed Chair before Powell's term ends in just over a year's time will give inventors plenty food for thought over the long weekend and Easter holiday.
