Rank 2. RBI's diaspora deposit scheme draws $56.8 billion, reshaping currency riskSource economictimes.indiatimes.com
India's Reserve Bank has attracted more than $56.8 billion in diaspora deposits through a special foreign-exchange scheme, exceeding initial targets and prompting an extension of the program's deadline. The large inflow shifts currency risk onto the RBI's balance sheet rather than onto individual banks, as lenders are now deploying the funds through asset-side strategies rather than relying on deposit spreads. The scale of the program marks a structural change in how India manages external financing and central-bank exposure to exchange-rate volatility.
