For the second day in a row, the U.S. dollar has appreciated significantly against the Euro and is also trading higher against the New Zealand dollar and Swiss Franc. However, the extent of today’s rally in the greenback basically ends there. The dollar is practically unchanged against the British pound and Australian dollars and is trading lower against the Canadian dollar and Japanese Yen. The 2.3 percent sell-off in U.S. equities coupled with the outperformance of the two lowest yielding G7 currencies indicates that risk aversion is the dominant theme. Yet, with no major U.S. economic data or market moving news over the past 48 hours, traders may be wondering, what changed. As recently as last week, investors were optimistic about a turnaround in the global economy following the more substantial outcome from the G20 meeting.
