Why Central Banks Never Get Everything They Want
Imagine a referee who must run the match, play defence, and keep the crowd calm — all at once. That’s a central bank.
Institutions like the Reserve Bank of India or the Federal Reserve don’t get to choose perfect outcomes. They face a trilemma — three good goals, but they can only fully achieve two.
Goal one: Stable interest rates.
If short-term rates swing wildly, policy signals lose meaning. Businesses can’t plan, banks can’t price risk.
Goal two: A small balance sheet.
Ideally, a central bank should referee markets, not dominate them. Too much money parked with the central bank can choke market activity.
Goal three: Minimal intervention.
Markets are meant to discover prices on their own. Constant central bank action distorts behaviour and creates dependency.
Here’s the catch:
To stabilise rates, central banks often intervene.
To intervene, balance sheets expand.
To shrink balance sheets, rate control becomes harder.
So central banks compromise — always.
In India’s case, the RBI also juggles growth, inflation, government borrowing, currency stability, and financial inclusion. That makes its trade-offs even tighter.
The takeaway: when markets complain that “the RBI isn’t doing enough” or “central banks are distorting markets,” they’re often asking for the impossible.
Central banking isn’t about control. It’s about choosing which pain to accept.
