Why too much money in the banking system is a problem for the RBI

The article discusses the challenge faced by the Reserve Bank of India (RBI) due to excessive liquidity in the banking system, which reached a four-year high. This surplus liquidity, primarily driven by foreign-currency inflows from a special US dollar-rupee forex swap facility and FCNR(B) deposits, puts downward pressure on overnight money-market rates and could fuel inflationary pressures. The RBI's dilemma is to drain this excess liquidity without causing a sharp rise in interest rates or disrupting the government securities market, especially when global central banks are tightening monetary policy. The article details various tools the RBI employs or could employ for liquidity management, including Variable Rate Reverse Repo (VRRR) operations, temporary Cash Reserve Ratio (CRR) hikes (or Incremental CRR), Open Market Operations (OMO) sales, and managing its forward book and spot dollar sales.
