Korea's chip boom catches US Fed chair's eye

What happened: The US Federal Reserve held its key rate steady, and Chair Kevin Warsh cited South Korea's role in global technology supply chains as a reason for tracking its economy. Key numbers: Fed target rate unchanged at 3.75 percent to 4 percent. BOK base rate at 3 percent, leaving a gap of up to 1 percentage point. Why it matters: The BOK is expected to keep tightening despite the Fed hold, with another rate hike anticipated at its Nov. 26 meeting, as strong growth and inflation above the 2 percent target add to its policy dilemma.
