If your country's government is raising the interest rate, it is not a bluff. It is a real thing. I won't expect an announcement to made and yet the cost of borrowing remains the same. And, for sure, your country's economic, monetary, and financial team has find reasons that call for the rate hike. It might be to temper down a rising inflation, but never to take it away. Inflation is an integral part of any economy.
Anyway, interest rates rise and fall. It is normal. There is no reason to react to it too much.
And, please, don't think the central banks would just let fiat die. In the first place, they are there to let it live for as long as possible.
They won't even if they are printing massively. This is the lifeblood of their financial system no matter what.
Inflation will always be a part in any economic system as we move forward in this life.
This is the reality and we need to face it. This is not a bluff anymore so we need to act on it rather than treat it as nonexistent.
This is not a problem of only one country but this is global concern so you are not alone experiencing this kind of economic problem.
