The Central Bank could just buy the mortgage bonds by putting the mortgage on the asset side of the book and issuing currency on the liability side of the book. The Bank of Canada only does this to manipulate the overnight interest rate, on Government of Canada bonds. However, all rules have been thrown out the window these days.
The cannot stop. At least not with the current currencies.
Look at Japan's interest rates. It's not gonna happen, because it will destroy a complete country and surroundings.
People who took a shorter term for the interest rate in the past 10 years, now have a housing cost of a few hundred euros, because it came down from 3-4%.
I’m saying that when mortgage rates double, the cost of buying homes will effectively double. Buyers simply won’t be able to afford to pay as much and prices will plateau or even dip.
There are people paying 1M for hones in my neighborhood that sold for 500k ten years ago because their mortgage will be only $2K a month. When it’s $4K a month those buyers are gone. That’s why I’m selling soon.
I gather, from this thread, that this is not the case in Canada and some other locales. But in the U.S, if you have a fixed-rate mortgage, your interest rate is fixed for the full length of the loan. It sounds like the OP is from Europe, where I guess things work similarly.
