BENGALURU, July 21 (Reuters) - Indian shares closed near a seven-week high on Thursday, led by gains in metals and auto stocks, while strong results from IndusInd Bank lifted private lenders.

The NSE Nifty 50 index and the S&P BSE Sensex rose 0.51% each to close at 16,605.25 and 55,681.95, respectively. Both the indexes closed at their highest since early June.

"The return of foreign investors to domestic equity markets in the last few sessions, coupled with receding commodity prices and hopes the U.S. Fed may not go for aggressive rate hikes in its next meeting have somewhat tempered fears," said Shrikant Chouhan, head of equity research (retail), Kotak Securities.

"The chip crisis is easing and raw material costs have come down for automobile companies, and they have passed on the hikes to customers. The market is expecting better margins," said AK Prabhakar, head of research, IDBI Capital.
