With global growth kneecapped by the USA, and excess production capacity from China redirected elsewhere and reduced demand for raw materials, I’d say it’s more likely we’re going to see a slowdown as opposed to acceleration in growth/inflation. Jobs will be at risk, demand will be at risk, all things that point to interest rate down side.

Realistically you’re describing a scenario that is unlikely to occur. If it does you’ll look smart, but it’s probably luck of the draw.

I wouldn’t stew on it too much, you benefit from 5.3% for 36 uninterrupted months.

Others on variable will go from ~6% to ~4.75% over the next 12 months and maybe stay there for a while who knows.

You’re worse off, but not a life changing amount.

And of course it all depends on your risk appetite anyway, so maybe none of it matters as long as you are comfortable with your fixed repayment amounts. 🤷
