Interacting with mediapersons outside Parliament, Mukherjee said the economy grew at 8.9 percent, more than expected in the quarter through September.

Amidst all depressing news, one good news is there that second quarter GDP growth has been 8.9 percent. And they have revised the first quarter also to 8.9 percent. That means we may be confident that the GDP growth at the end of the year will not be less than 8.7 to 8.75 percent, which we projected,

I always go by conservative estimate. International Monetary Fund (IMF) estimate, as I mentioned earlier, have already projected growth to be more than 9 percent,  he added.

India's economy grew a faster-than-expected 8.9 percent in the September quarter from a year earlier, data released on Tuesday showed. The median forecast in a Reuters'' poll was for an annual rise of 8.3 percent. The GDP growth for the April-June quarter was revised upwards to 8.9 percent from the provisional figure of 8.8 percent.

Economy grew more than expected in September quarter, boosted by farm output and manufacturing, putting pressure on the Reserve Bank of India (RBI) to tighten monetary policy although a rate increase next month still looks unlikely.

The strong GDP growth comes despite the RBI raising key rates by 150 and 200 basis points respectively since mid-March to anchor inflationary expectations.
