I was asked this in JPMC. Here's what I told them-
There will be capital flight from US as the confidence in the economy goes down because of fear of retaliation from North Korea and investors would flee to safer haven like Europe. This would lead to depreciation in USD.
After that, even South Korean won will take a hit as that region would be in frenzy.
Then they asked me what commodity markets would be affected.
At this point I fumbled and said all the sectors would take a hit. What could have been an ideal answer?
