The Indian rupee slipped to a historic low on March 19, reflecting a convergence of external shocks that are rapidly tightening financial conditions for emerging markets. The currency weakened 0.65% to 93.24 against the US dollar, breaching its previous record low of 92.63 set just a day earlier. Since the escalation of the US-Iran conflict, the rupee has depreciated nearly 2%, underlining the speed at which global geopolitical risks are transmitting into domestic currency markets.

At the heart of the current pressure is a sharp surge in crude oil prices, which briefly approached $120 per barrel after attacks on critical energy infrastructure in the Gulf region. Although prices eased marginally on Friday, the volatility has already altered macro expectations. For an import-dependent economy like India, oil remains a key vulnerability, directly impacting both inflation and the current account balance.

The geopolitical backdrop remains fluid. The United States has indicated measures to increase oil supply, while major economies including European nations and Japan have offered to support efforts to secure shipping routes through the Strait of Hormuz. However, markets appear unconvinced about near-term stability, with risk premiums in energy markets staying elevated.

This uncertainty has translated into capital market stress. Foreign institutional investors have pulled out more than $8 billion from Indian equities in March so far, marking the largest monthly outflow since January 2025. The scale of these outflows suggests a broader risk-off shift, driven by both rising US yields and geopolitical concerns. A stronger dollar environment has further compounded the pressure on emerging market currencies, including the rupee.

From a policy perspective, the global interest rate environment is adding another layer of complexity. The US Federal Reserve’s decision to maintain rates in the 3.5–3.75% range, coupled with elevated inflation projections, has reinforced expectations of a prolonged “higher-for-longer” cycle. According to Axis Securities’ Head of Research Rajesh Palviya, sustained dollar strength could continue to exert pressure on the rupee while also triggering intermittent foreign outflows, particularly in debt markets. This suggests that currency stability may remain elusive in the near term despite India’s relatively strong domestic fundamentals.

Economists are now revisiting their macro projections in light of the oil shock. Nomura’s Sonal Varma estimates that every $10 increase in crude oil prices could push inflation higher by 50 basis points. As a result, FY27 inflation expectations have been revised upward to 4.5% from 3.8% earlier. While growth is still projected to remain resilient at around 7%, the balance between growth and inflation is becoming increasingly fragile.

The implications for India’s economy are multi-layered. On one hand, higher oil prices can widen the current account deficit and weaken the rupee further, creating a feedback loop. On the other, imported inflation could limit the Reserve Bank of India’s ability to ease monetary policy, especially if global central banks remain hawkish.

From a sectoral standpoint, the impact is uneven. Oil marketing companies and aviation firms face margin pressure due to higher input costs, while upstream energy players may benefit from elevated crude prices. Rate-sensitive sectors such as banking and real estate could also see indirect effects if inflationary pressures delay any potential rate cuts.

Market participants are now weighing two divergent scenarios. In a bullish case, coordinated global efforts to stabilise oil supply and ease geopolitical tensions could bring crude prices down, allowing the rupee to recover gradually. Strong domestic growth and policy stability could also help absorb external shocks. However, the bearish scenario remains equally plausible. A prolonged conflict, sustained oil prices above $100 per barrel, and continued FII outflows could push the rupee into deeper depreciation territory, while also forcing tighter monetary conditions domestically.

The key risk lies in the persistence of external shocks. If oil prices remain elevated for an extended period, India could face a combination of higher inflation, currency weakness, and constrained policy flexibility. Additionally, any further strengthening of the US dollar or escalation in geopolitical tensions could amplify volatility across both currency and equity markets.

In the near term, the rupee’s trajectory will largely depend on the evolution of the Middle East conflict, global oil price stability, and the direction of foreign capital flows. While India’s macro fundamentals offer some cushion, the current episode highlights the economy’s continued sensitivity to global energy and financial cycles.
