Investors are focusing more closely on data as they weigh the odds of when the Fed is likely to start unwinding its $85 billion-a-month bond-buying campaign. Many investors expect the Fed will begin tapering in the first quarter of next year if the economy continues to improve.
"On tapering and USD, we have been struck by how much of the market continues to assign a very low probability of a December or January tapering," Englander said.
"Investors are focused on next week's labour market release, but the stronger than expected data suggests that some revision of probabilities is merited even going into the numbers."
