The Indian rupee hit a nearly 1-1\/2 year high against the dollar on Monday, tracking gains in Asian currencies after U.S. President Donald Trump's failure to pass a healthcare reform bill raised concerns about the chances of a US fiscal stimulus. The Reserve Bank of India stepped in to cap broader gains in the rupee, traders said, adding that some of the gains were also due to the strong $6.1-billion foreign investment into debt and equities this month. The gains in the local unit spurred by strong dollar inflows helped spark a rally in bond markets, sending the benchmark 10-year bond yield down as much as 12 basis points to 6.71 percent, the lowest since Feb. 8 when the central bank unexpectedly changed its monetary policy stance to "neutral" from "accommodative." However, shares fell as software services exporters and drug makers were hit by worries about the impact of a stronger rupee.

"Both global and domestic factors are riding the market today," said Vinod Nair, head of research at Geojit Financial Services. At 0656 GMT, the rupee was trading at 65.0575 after earlier strengthening to as much as 65.01 per dollar, the strongest level since October 2015.
