The rupee flirted with record lows on Wednesday despite a slew of government measures to narrow the current account deficit, with inflation data later in the day expected to show further strains on the ailing economy.
Economists polled by Reuters expect the July wholesale price index to have risen slightly to 5 percent from a year earlier, hitting the ceiling of the Reserve Bank of India's perceived comfort zone. The headline inflation data will be released at 12.00 IST.

The RBI's risky gambit to drain cash from the system and raise short-term interest rates have also failed to prop up the currency, with the rupee down 2.6 percent since the initial set of measures were unveiled on July 15.
A recovery is seen as unlikely given data showing continued economic weakness, with data on Tuesday showing industrial output in June contracting more than expected.
Although inflation concerns had recently eased on the back of a good rainy season, a weakening rupee could change that equation, pushing up in the near-term prices of India's two biggest imports: oil and gold.
The government on Tuesday raised import duties on gold, sending prices for the most-actively traded gold for October delivery on the Multi Commodity Exchange (MCX) to a four-month high on Tuesday, while the country has also said it plans to
