Dan Scott, deputy CIO of Vontobel, told CNBC's "Street Signs" that the banking stock woes were most likely tied to negative rates ahead of Powell's testimony.
"In the rates perspective, it was clear already from Jackson Hole that the Fed is open to the fact that it can't set rates in isolation, i.e. when Europe is in negative territory, when Japan is in negative territory, the Fed can't have such a high policy rate," Scott said.
"It was clear that this rate cut we just saw, the last 25 basis points, had to come, and now it's up for debate whether we get another 25 basis points before year end," he added, while contending that the U.S. does not need another rate cut before 2020.
