Rupee Volatility Rises as RBI Intervention Wanes and Arbitrage Grows

The Indian rupee faced significant pressure on Thursday, erasing early gains as central bank-led dollar supply diminished. The currency's inability to sustain its upward momentum highlights the growing impact of arbitrage flows and shifting global macroeconomic signals on the domestic forex market.

Early Gains Faded as Dollar Supply Thinned

The rupee initially showed signs of strength, climbing to a peak of 94.9375 in early trading sessions. This upward movement was primarily driven by active dollar sales from state-run banks, which aimed to stabilize the currency after it hit a near three-week low on Wednesday. Traders reported that these banks were offering dollars near the 95 level to support the rupee.

However, this support was short-lived. As the aggressive dollar supply from state-run entities faded by midday, the rupee reversed course. Once the critical 95 mark was breached, it triggered a wave of stop-loss orders on long rupee positions, causing the currency to slide. By the end of the session, the rupee was trading at 95.2775, signaling a loss of momentum.

Arbitrage Flows and Technical Triggers Pressure the Rupee

Beyond the lack of central bank intervention, two specific technical factors weighed heavily on the rupee. First, a sudden surge in dollar demand related to arbitrage trades between the non-deliverable forward (NDF) and the onshore deliverable market put downward pressure on the domestic currency.

Second, the breach of the psychological 95 level acted as a catalyst for further depreciation. Market participants noted that once the 95 threshold gave way, some state-run banks were even spotted buying dollars rather than selling them. Traders in Mumbai warned that the USD/INR pair remains prone to further upward movement (rupee depreciation) in the absence of consistent dollar supply from the Reserve Bank of India (RBI).

Global Macro Factors: The Fed and US Payrolls

The rupee's struggles are not occurring in isolation. Most Asian currencies remained rangebound on Thursday as investors shifted their focus toward the United States. Markets are currently bracing for the crucial June non-farm payrolls report, which is expected to be a major volatility trigger.

If the payrolls data comes in stronger than expected, U.S. Treasury yields are likely to climb, which would strengthen the dollar and increase pressure on emerging market currencies like the rupee. Furthermore, recent comments from Federal Reserve Chair Kevin Warsh, emphasizing a focus on containing inflation and reinforcing bets on potential interest rate hikes in 2026, have provided additional support to the greenback, keeping global investors on high alert.

Key Takeaways

  • Waning Intervention: The rupee's early recovery failed as state-run bank dollar sales subsided, leading to a reversal from a peak of 94.9375 to 95.2775.
  • Technical Pressure: The breach of the 95 level triggered stop-losses on long rupee bets and coincided with increased dollar demand from NDF-onshore arbitrage trades.
  • Global Sensitivity: The domestic currency remains highly sensitive to U.S. economic data, specifically the upcoming non-farm payrolls report and shifting Federal Reserve interest rate expectations.
