RBI's New Forex Rule Faces Market Reality

The Reserve Bank of India (RBI) recently placed a $100 million limit on banks' foreign currency trading positions. This move, effective April 10, 2026, aimed to reduce currency swings caused by trading strategies. Banks had to unwind positions worth billions, aiming to curb speculation and support the Indian Rupee, which had been weakening. Initially, the market seemed to comply, with the rupee weakening slightly and forward currency rates rising. However, the actual market response proved more complicated.

Companies Find Arbitrage Loophole

As banks sold dollars onshore to meet the RBI's limits, they sought to balance their positions in offshore currency markets. This created a significant price difference. Indian companies quickly took advantage of this price gap, engaging in arbitrage. On March 30, trading in these offshore markets jumped to about $7.54 billion, with companies actively buying dollars to exploit the gap. This rush to buy dollars from companies pushed the rupee to new record lows, above 95 per US dollar, despite the RBI's efforts. The RBI then tightened its rules, preventing local banks from offering these offshore services to clients and stopping companies from rebooking canceled future currency contracts, trying to regain control.

Global Economic Challenges and Asian Currencies

The RBI's actions come as India's economic growth forecasts moderate and global geopolitical risks persist. The World Bank forecasts India's GDP growth at 6.6% for fiscal year 2027, down from an estimated 7.6% in FY26, partly due to conflict in the Middle East and higher energy prices. Inflation is expected to be 4.6% in FY27, with potential risks from high energy prices. Meanwhile, other Asian currencies are also under pressure. The Indonesian rupiah and Philippine peso hit record lows in March, and the South Korean won reached a 17-year low, unlike the stronger Chinese yuan. The Indian rupee has weakened 0.92% in the past month, despite recent RBI interventions. Historically, the RBI has intervened to smooth out large currency swings, aiming to reduce volatility rather than target a specific exchange rate, a strategy that has often worked.

Impact on Banks and Market Liquidity

The RBI's strict regulatory approach, while aimed at stopping speculative trading, carries risks. Banks are facing immediate profit hits, with estimated sector-wide losses from unwinding positions between ₹40 billion and ₹50 billion. These measures, such as limiting offshore currency contracts, could reduce overall market liquidity in the long run. Fitch Ratings warns that continued pressure on the rupee could limit the RBI's capacity to add liquidity to the banking system, as actions to support the currency naturally reduce local currency available. These regulatory steps might not fix deeper structural issues in foreign exchange, potentially leaving the rupee vulnerable. The rapid emergence of corporate arbitrage shows how quickly markets can find new profit opportunities, questioning the effectiveness of single regulatory actions.

Outlook for the Rupee

Analysts expect the USD/INR currency pair to trade within a range, highly sensitive to oil price changes driven by ongoing global tensions. The RBI's recent moves are seen as short-term steps to curb speculation, while the bank maintains a commitment to promoting the rupee's international use over time. The central bank maintains a neutral monetary policy, keeping the repo rate at 5.25%. Its main focus is currency stability, possibly over supporting deeper liquidity. With projected GDP growth of 6.6% and inflation at 4.6% for FY27, the economy faces a balance between supporting growth and managing external risks.
