Rupee retreats to near two-week low as US-Iran standoff pushes oil higher

The Indian rupee weakened to near a two-week low on Tuesday as oil prices surged amid fears of a U.S.-Iran deal collapsing, preventing the Strait of Hormuz from reopening. However, the Reserve Bank of India's (RBI) likely intervention helped curb the currency's decline. At the day's end, the rupee closed at 95.4350 per dollar, marking a 0.15% drop from its prior close.

This decline also impacted equities, with the Nifty 50 falling 0.5% and the benchmark 10-year bond yield increasing by 3 basis points. India's vulnerability to oil price fluctuations is evident, given its reliance on imported crude, accounting for nearly 90% of its consumption needs. Brent crude oil futures soared nearly 2.5%, reaching $89.9 per barrel.

A private bank trader noted that the absence of significant outflows or derivative maturities assisted the rupee on this particular day, but if oil prices continue to rise, the rupee may hover around 95.80 unless the RBI intervenes decisively. The central bank's repeated interventions throughout the week have kept expectations of dollar-rupee volatility in check, despite renewed concerns over Middle Eastern conflict.

The dollar-rupee's 1-month implied volatility, a measure of future expectations, fell to 4.6% on Tuesday, its lowest level since late June, indicating market confidence that the RBI will prevent sharp fluctuations. Beyond Middle East developments, the week is also focused on India and U.S. consumer inflation data, both scheduled for release on Wednesday.

Analysts at DBS suggest that if Brent crude prices stabilize around $70-100 per barrel, it would mitigate geopolitical risks stemming from the U.S.-Iran conflict and maintain a data-dependent stance in the foreign exchange market.
