Fascinating. Thanks for the info. I'm in northern Europe (Norway), and very curious how this could spread east of the Atlantic. Historically, our central bank has given everyone the impression that they decide the mortgage rate, but history has shown that foreign rates have much higher impact.
In the previous 20 years, whenever rates have spiked abroad, the central bank has made interventions to prevent domestic rates from going up. But those interest rate spikes have been transistory, so I have no idea how things would play out this time.
