(Reuters) – UBS on Wednesday joined the growing list of brokerages lowering India’s 2011/12 economic growth forecast, paring Asia’s third-largest economy’s growth to 7.7 percent from 8 percent, as interest rate rises and higher oil prices start to bite.

Morgan Stanley and Bank of America-Merrill Lynch had last week lowered their growth forecast for the Indian economy in the next fiscal year that begins in April to 7.7 percent and 8.2 percent.

UBS also cut the world’s second-fastest growing major economy’s gross domestic product forecast for the current fiscal year to 8.7 percent from 9 percent on weak December-quarter growth and continuing weakness in the industrial output growth.

“The reason for the slowdown is as before: lagged impact of todays tight money on demand plus effect of higher oil prices,” Philip Wyatt, an economist at UBS wrote in a note, adding he sees the economy recovering to 8.6 percent growth in 2012/13.

India’s economy grew at a slower-than-expected 8.2 percent in the December quarter from a year earlier, after expanding at 8.9 percent in the previous two quarters.

Industrial output in January topped forecasts, but was still weak at 3.7 percent annual rise.

“We expect WPI (wholesale price index) inflation to accelerate from 7 percent in March 2011 to 7.7 percent a year hence,” Wyatt wrote.

India’s headline inflation unexpectedly quickened in February on rising fuel and manufacturing prices, raising expectations for aggressive central bank tightening beginning later this week. (more…)
