RBI uses currency swaps to cut $115 billion cash surplus
India's central bank is draining excess cash from banks using currency swaps. This action follows record high funds in the financial system. The Reserve Bank of India sells dollars for rupees, reducing rupee liquidity. Massive inflows had previously pushed surplus funds to 11 trillion rupees. These measures aim to manage inflation risks posed by cheaper borrowing.

Economic
A currency swap is a derivative contract between two parties, typically central banks or commercial banks, to exchange specific amounts of two different currencies. In this scenario, the employed a sell-buy swap, selling US dollars to domestic banks in exchange for Indian rupees, with an agreement to buy the dollars back at a predetermined future date. This action immediately extracts rupees from the banking system, addressing the problem of excess liquidity (the availability of cash or easily convertible assets). The utilizes these swaps as part of its liquidity management operations to maintain the stability of the domestic financial system. If left unchecked, excessive liquidity can lead to higher inflation as more money chases the same amount of goods and services, and it can also depress short-term interest rates below the 's target rate.
Governance
The 's intervention highlights the challenges central banks face in managing the consequences of large foreign capital inflows. While foreign investment is generally desirable for economic growth, it can create a 'trilemma' for monetary authorities. When foreign investors bring in capital, they exchange their foreign currency (e.g., US dollars) for domestic currency (rupees). This increases the supply of rupees in the domestic market, leading to the massive liquidity surplus observed. To prevent the rupee from appreciating too rapidly, which would hurt exports, the often intervenes in the foreign exchange market to buy dollars. However, this creates a secondary problem: it injects even more rupees into the domestic economy, exacerbating the liquidity issue. The use of currency swaps is a tool for sterilization, a process by which the central bank neutralizes the impact of its foreign exchange interventions on domestic liquidity without immediately resorting to selling government bonds, which could disrupt the domestic bond market.
Financial Markets
The article notes that the 's swap operations caused three-month dollar-rupee onshore forward yields to rise. The forward premium represents the difference between the spot exchange rate (the current price) and the forward exchange rate (the agreed-upon future price). When the engages in massive sell-buy swaps, it creates a high demand to buy dollars in the future. This increased demand pushes up the future price of the dollar relative to the rupee, thereby increasing the forward premium. Analysts point out a critical limitation: sell-buy swaps only postpone the liquidity problem; they do not eliminate it. When the swap matures, the must buy back the dollars, releasing rupees back into the system. Furthermore, large interventions can distort the forward market, increasing hedging costs for businesses and potentially raising the 's own costs when it rolls over the swaps (extends them to a new maturity date).
