There’s uncommon dissent in the ranks of the Federal Reserve’s primary dealers over the central bank’s interest-rate decision this week.

Two of the Fed’s 23 preferred bond-trading partners — Barclays Plc and BNP Paribas SA — are betting against their peers and the bond market by forecasting officials will raise rates Wednesday. It’s the first time more than one dealer has gone against the consensus during the week of a policy meeting since last September, data compiled by Bloomberg show. Economists at both banks say traders have too steeply discounted officials’ intent to hike after the Fed has remained on hold for longer than expected.

“There is no perfect time — there will always be some uncertainties in the data,” said Laura Rosner, senior U.S. economist in New York at BNP. “Despite a multitude of shocks through the last nine months, which have delayed the Fed, hiring has continued to be robust. There is a window of opportunity for the Fed to continue normalizing, and we think it’ll take it.”
