Why are central banks independent?

So money printing isn't used for politics

After a decision, central banks usually...

Publish a statement explaining it

The lira fell and inflation soared

Give a government the power to print money before every election, and it'll be tempted to use it. That's why Bank Indonesia, Mexico's Banxico, the European Central Bank and many others are independent by law.
Cutting rates or printing money feels good now: cheaper loans, more spending. The bill, inflation, arrives later, often after the vote.
Real example: in 2021 Turkey's central bank cut rates under heavy political pressure while inflation was rising. The lira lost about 44% against the dollar that year, and inflation passed 80% in 2022.
Independence lets central banks do unpopular things. In 1979–81 Fed chair Paul Volcker pushed US rates to around 20% to crush inflation. It hurt, but inflation fell from over 13% to about 3% by 1983.
Trust is the real tool. If people believe prices will stay stable, workers and firms don't rush to raise prices, so inflation is easier to keep low.
Common mistake
Mistake: “independent means unaccountable.” Central banks have targets set by law, publish their decisions and explain them in public. They just can't be ordered around day to day.
Key takeaway
Independent central banks protect your money's value from short-term politics. Credibility keeps inflation low.
