Although it will be painful it's probably best that interest rates return to a more normal level. People on this thread are talking about how rate increases will cut down on discretionary spending, but high housing costs have already been causing this for years and no one seemed to mind. The more money you spend on your mortgage/deposit the less you have to spend on everything else. Higher interest rates will make this worse, but they aren't the root cause.
I'm in my 30s so I know a lot of homeowners that have only ever known low interest rates and rising prices. I have empathy for people that may have overextended themselves and will struggle to make ends meet. It's not their fault that they had to buy into such a dysfunctional market.
However, I have also watched a lot of people make a lot of questionable financial decisions since becoming a homeowner. People who have taken out the maximum mortgage rather than live in a slightly less desirable area nearby, then a few years later when they'd built up some equity take on six-figure loans to extend, happily telling everyone who will listen just how much everything cost as if it was monopoly money (and reducing the number of homes suitable for FTBs in the process). They are willing to take on debt that may be larger than they are initially comfortable with because they think there is no risk.They also tend to save less because they assume their equity will be enough to fund their future moves up the ladder or their retirement.
This is across all social classes. I have many friends in London and my DP is from an industrial town up north. I have lost count of how many people have told me "my house earned more than me last year" as if that's a good thing. They are happy to ignore their stagnant wages because the housing market has tricked them into thinking they're wealthy. But being "house rich cash poor" is a real thing. We actively avoid certain groups of people now because all they ever talk about is how much their house value has gone up.
Having a population that understands that interest rates can go up, property prices can go down, and there are risks associated with borrowing large sums of money is a good thing in the long term. It's just really unfortunate that the government has let the housing market get to this state and so many people will have to suffer so much hardship.
