I (like I'm sure many others) predicted it in 2007 and hedged against it by getting a 10 year fixed mortgage at then-current rates on the basis that rates would go sky high as they had in earlier recessions in the UK.
They plummeted to next-to-zero, and in addition to the injury I had to endure the insult of the people who hadn't seen it coming gloating about their low standard variable rates.
Ofc I clearly didn't have much real economic understanding but I guess I am saying that beyond normal common financial sense (the lack of which at scale leads to these situations) which you should be using anyway, we don't really know which way the wind is blowing, and what the exact consequences will be.
Why you could not refinance when the rates went to 0%? In the US a lot of people did that in 2009/2010 and then again during COVID
I remember the opposite, just before we left the ERM (European Exchange Rate Mechanism). Interest rates hit 15% and one of my colleagues was gloating about how he had just taken on a fixed rate mortgage. A few days later we left and interest rates plummeted.
