By Swati Bhat and Abinaya V MUMBAI, Dec 5 (Reuters) – The Reserve Bank of India (RBI) cut its key repo rate by 25 basis points on Friday and took steps to boost banking-sector liquidity by up to $16 billion to support a “goldilocks economy”. The six-member monetary policy committee voted unanimously to lower the repo rate to 5.25%, in line with a consensus view, and maintained a “neutral” stance, suggesting room for further rate cuts.
