Yes, it's something we also do work on in terms of stress-testing loans that we would make for producers and our overall portfolio.
The answer to that question really revolves around how far it goes and how fast it moves. If there's very little time to adjust, I think that creates more challenges, for sure. Our expectation is that 100 basis points or even 200 basis points of increase in interest rates over a period of several years is something that the industry would be able to adjust to. If we move very rapidly through that same type of a cycle, 200 basis points over several months versus years, I think that would put some pressure on some operations to adjust. There is flexibility within our book. Based on the average amortization we would do on a new mortgage loan it would be less than 20 years.
So in terms of people stretching out their loans and some of the options we would have to adjust to that, I think there are lots of things we could do from a financial institution perspective to help provide some cash for relief in a really extreme circumstance. But yes, a return to what would be maybe more normal rates historically, in a very rapid fashion, would create some cash flow challenges, without a doubt.
