'We made money in the last few days'.
"We made money in the last few days and we helped our customers," he said. "It hasn't been a big impact on us but it caught everybody by surprise."
Speaking from the World Economic Forum in Davos, Switzerland, Moynihan said that his bank made money in the currency markets and trading in the wake of Thursday's announcement that the Swiss franc would no longer be pegged to the euro.
He said the Swiss National Bank decision was good even though it caused some "dislocation in the system."
"The volatility helps activity, and if you keep your exposures low, any activity actually helps generate revenue," he said. "We were fine, and we look forward to letting the economy adjust."
