Federal Reserve Chairwoman Janet Yellen said Tuesday that she doesn't expect another financial crisis during her lifetime.

"Would I say — will there never, ever be another financial crisis? Probably that would going too far," Yellen said during a question-and-answer session at the British Academy in London. "But I do think we're much safer, and I hope that it won't be in our lifetimes — and I don't believe it will be."

The central banker touted the rules that the Fed has implemented in the aftermath of the financial crisis and warned against undoing them.

Warning of the dangers of bank crises, Yellen said that "memories do tend to fade. I hope that that won't be the case."

The Trump administration and congressional Republicans are trying to reduce the burden of financial regulations. While Yellen said that some rules could be revisited to make them less onerous, she said that any relief should be done "without any way compromising" the rules meant to make banks safer.
