The dollar weakened against most major currencies on Friday, weighed down by an unexpected decline in U.S. retail sales last month that once again dimmed expectations for an interest rate increase in December.

U.S. retail sales unexpectedly fell in August as Hurricane Harvey likely depressed motor vehicle purchases, dropping 0.2 percent last month. Economists polled by Reuters had forecast retail sales nudging up 0.1 percent.

Looking ahead, the market is now focused on next week’s Federal Open Market Committee meeting, in which the Fed is expected to start reducing its balance sheet. There is, however, zero expectation for an interest rate hike.

“The Fed’s tone and stance during next week’s FOMC statement and press conference will play a major role in setting expectations for interest rates, the Fed’s balance sheet reduction plans, and the U.S. dollar going forward.
