In the news from the economy. India’s trade deficit in July widened to the most in more than five years, worsening the outlook for the rupee that hit a record low on Tuesday.

According to data released by India’s commerce ministry, the gap between exports and imports reached US$18 billion in July, fanned by a higher oil import bill.

The trade shortfall puts pressure on the current-account deficit, a key vulnerability for the economy and one of the reasons why the rupee has been among the worst-hit in Asia amid an emerging-market rout this year.

The rupee dropped to as low as 70.08 per dollar on Tuesday as a collapse in Turkey’s lira hit investor sentiment, taking the slump in India’s currency down to 8.6% this year.

While a weaker rupee is positive for exports, it poses an inflation risk for a nation that imports more than 80% of its crude-oil needs. Every rupee change in the exchange rate against the US dollar impacts India’s crude oil import bill by Rs 108.8 billion (US$1.58 billion), according to the oil ministry.
