Judging from the reaction of stocks, bonds and currencies after the Fed statement, the market is afraid of the risk that the Fed is mistakenly tightening into a slowing economy. We do not share the market's fears to the same extent. But if this risk-case scenario materializes, the U.S. dollar would experience temporary upwards pressure. In turn, this would exacerbate currency concerns in China and other emerging markets.
Admittedly, this dollar appreciation would likely be short-lived. Soon, the dollar would decline as the Fed reversed course and rethought its plans for tightening as the economy faltered. A weaker dollar would help alleviate pressure on the Chinese yuan and other emerging-market currencies. But, in this risk-case scenario, to assume a more positive outcome for the yuan and emerging markets on a permanent basis may be jumping the gun.
