South Korea’s economic risk outlook has shifted as U.S. institutional guardrails around monetary and trade policy become more openly contested, forcing allies and central banks to respond in real time.

That shift has been catalyzed by three developments unfolding in close succession:

An unprecedented, coordinated statement by global central bank leaders defending the Fed’s independence; and
The continued absence of a ruling by the U.S. Supreme Court on the scope of presidential authority over so-called “reciprocal” tariffs.
