* Investors were also relieved by the nomination of former Federal Reserve Governor Kevin Warsh to head the U.S. central bank when Jerome Powell’s term ends in May. Warsh’s outlook will be closely analyzed in the coming days, at a time when the White House has been pushing for interest rate cuts.

* With the European Central Bank holding firm on its monetary policy, attention is now turning to the U.S. Federal Reserve’s interest rate outlook.
