Raising interest rates on its own doesn't do anything about inflation at all, actually. When you raise interest rates you are decreasing demand for borrowing but even that on its own doesn't decrease inflation. Inflation slows down as people pay off their debts as this destroys money that was previously created through loans. It's basically a side effect, not the main effect.

If you have a bankrupt government that can't afford interest payments, then raising interest rates will just lead to borrowing more money to pay the interest in a vicious cycle until hyperinflation sets in.

If you can limit borrowing and speed up payback of debts through any means other than raising interest rates you achieve the same effect much sooner.
