India's consumer-price growth sped up again in May as more of the impact of the Middle East conflict fed through, a development that could fuel rate-hike expectations.

The consumer-price index rose 3.93% last month, compared with a 3.48% increase in April, government data showed.

That missed the 4.0% that economists in a Wall Street Journal poll had projected as higher energy costs stoke inflationary pressure in economies like India that rely on oil and gas imports.

Market bets on hawkish tilts by central banks have been rising as the Iran crisis drags on, crystallizing the risk of the highly undesirable combination of slowing growth and accelerating inflation.
