U.S. officials blamed Iran for the attack, which damaged the world's biggest crude oil processing plant and led to a 19 per cent surge in oil prices. Iran denied blame and said it was ready for "full-fledged war".
A jump in oil prices is a negative for emerging markets such as India, which is the world's third-biggest importer of oil.
The country's current account deficit
in the March quarter narrowed on the back of the merchandise trade deficit contraction but a surge in crude prices could balloon the deficit and wreck havoc with the currency.
The partially convertible rupee dropped nearly 1 per cent on Monday to 71.60 per dollar versus its previous close of 70.92.
India is also likely to miss its fiscal deficit target for the current financial year, despite receiving an additional dividend from the central bank, five government officials and advisers told Reuters earlier this month, as tax collections have sunk amid a sharp economic slowdown.
Growth focus to remain
Das said the monetary policy committee would continue to focus on growth with inflation expected to stay within the medium term target.
Asia's third largest economy expanded just 5.0 per cent year on year in the June quarter, its weakest pace since 2013, far below the median forecast of 5.7per cent.
"The numbers definitely look much worse. The number of 5per cent is a surprise. We are analysing why exactly it has happened," Das told CNBC TV18.
"Growth now is a matter of highest priority, especially with inflation remaining within 4per cent," he added.
The retail inflation rate rose to a 10-month high in August but stayed below the central bank's 4per cent medium-term target.
Analysts believe the slowdown could persist for two or three years while structural reforms are put in place.
A Reuters poll conducted after the last monetary policy decision in August predicted the RBI would cut rates by another 25 basis points at its October review and then by 15 basis points early next year.
