 Yeah, so between the sort of 2009 crisis and the pandemic, we had interest rates that were regularly flirting with or at actual zero. So very, very low interest rates. What Chair Powell is saying is that we're not likely to go back to that, but that doesn't necessarily mean that we're going to have rates at these levels forever. So rates are at 5.3% now. That's obviously a lot above that zero level that we were seeing before the pandemic. There's a lot of room in between here and there.
