RBI’s NRI deposit success creates a new liquidity challenge for the banking system

New Delhi (TIP): The Reserve Bank of India’s special foreign-currency deposit scheme, launched to attract overseas funds and strengthen the country’s external buffers, has turned out to be far more successful than anticipated. But the massive inflow of dollars has created a fresh challenge for the central bank: too much rupee liquidity in the banking system.
The special swap facility for Foreign Currency Non-Resident (Bank), or FCNR(B), deposits mobilised an unprecedented amount of foreign currency. By the time the window closed on August 31, FCNR(B) deposits had reached around $127.2 billion, while total inflows under the broader facility were about $136.37 billion, according to data cited in recent reports.
The scale of the response was dramatically higher than expectations when the scheme was introduced. The government had said on August 24 that total foreign-exchange inflows under the facility had already reached $73 billion by August 21, with FCNR(B) deposits accounting for $65.4 billion.
From dollar inflows to excess rupees
The basic mechanics of the scheme explain the problem. When NRIs place their dollars with Indian banks under FCNR(B) deposits, the banks can exchange those dollars with the RBI through the special swap arrangement. In return, the RBI provides rupees to the banks. The dollars strengthen India’s foreign-exchange reserves and provide banks with stable foreign-currency funding. But the rupees released by the RBI remain within the domestic banking system. They therefore add to overall liquidity rather than disappearing from circulation.
With the inflow reaching more than $127 billion, the impact has been enormous. India’s banking system liquidity surplus climbed to around Rs 9.7 trillion, or Rs 9.7 lakh crore, in early September, according to Reuters. Other estimates have subsequently put the surplus at around ?14-15 trillion as the RBI grapples with the continuing overhang.
Why excess liquidity matters
A liquidity surplus is not necessarily bad for banks. In fact, abundant funds can reduce their dependence on expensive market borrowing and give them greater capacity to lend.
But an excessively large surplus can complicate the RBI’s monetary policy operations. When banks have more money than they need, they may park funds in the overnight market, pushing short-term interest rates below the RBI’s desired operating level. Excess liquidity can also encourage additional lending and investment, potentially creating demand-side pressures and, eventually, inflation or asset-price risks.
