Will 0% balance transfer deals become scarce as a result of interest rates increasing?

inasitu

I currently have two 0% balance transfer cards which total 3k debt. 

NOTE: I only use the cards as a way to pay the debt off at £120 (minimum) per month without incurring interest – (I don’t use them for purchases etc, so the balance is always decreasing).

One card deal ends Jun 2023 and the other Aug 2023.

The way things currently are means the likely hood of the debt being cleared by the time the deal ends is a lot lower than it otherwise would have been.

Don’t know if I’d be right in assuming that free or low fee 0% balance transfer deals will become scarce or nonexistent the more interest rates increase.

So wondering: 

• If I should be looking to act now for a new 0% deal or wait?
• If It could somehow be viewed as bad moving a balance from a 0% balance transfer card which has 9 months of the deal left to go?

I think they'll be with us for a long time as it's a nice money earner for the card companies.  My deal offers have moved from 2% fee and have now edged up to 5%.  And as the balance rates increase there's the chance of making more when someone doesn't clear the balance in the X months of the deal - which are decreasing (from what I've seen) from 24 months to 15 and now down to 12.  So less reason for me to use them but others will, no doubt, still be tempted.

It was a good way in the past for me to pay less interest on my mortgage by using balance transfers between cards rather than paying a card balance from my flexible mortgage account.   A 2% fee over 24 months versus an annual interest rate of 4% on my mortgage.  Now things have reversed and this would just cost me more than it's worth.
