Indian rupee pressured by Iran talks impasse; RBI intervention a 'reliable' buffer

Mumbai markets opened with the Indian rupee facing new challenges on Monday as stalled US-Iran talks caused oil prices to surge. The local currency was projected to open slightly weaker, trading at 95.8125 to the dollar, based on trader projections. For currency traders, the 96-per-dollar mark has emerged as a crucial level over the past fortnight, with the Reserve Bank of India (RBI) frequently intervening to prevent the rupee from sliding past this threshold.

The central bank's interventions have thus far thwarted a sustained dip below 96, despite the upward pressure from higher oil prices, climbing US Treasury yields, and a stronger dollar. A currency trader from a major bank remarked, "The RBI has been providing a dependable buffer thus far against all the adverse factors (for the rupee)."

However, the sustainability of this support remains uncertain as oil prices and US yields continue to climb. Importers are responding by increasing their hedging activities to mitigate the impact on their bottom line. The ongoing tensions in the Middle East have been exacerbated by US President Donald Trump's rejection of Iran's proposal to reopen the Strait of Hormuz, further fueling concerns about potential disruptions to oil supplies.

Brent crude oil prices surged 2.5% to approximately $107 a barrel in Asian trade, eroding the gains in US bonds. The 10-year Treasury yield rose to 5.2%, causing the US dollar to strengthen and adding to the pressure on the rupee and other Asian currencies. Longer-dated US Treasury yields have risen significantly in recent sessions due to robust economic data, which has intensified worries about the potential inflationary effects of higher oil prices.

The 10-year and 30-year yields are now nearing their highest levels in almost two decades. Furthermore, the optimistic economic data has boosted expectations of another rate hike from the Federal Reserve, with traders pricing in an over 64% probability of an increase in October.
