Foreign portfolio investors (FPIs) pumped in over Rs22,350 crore ($3.44 billion) in the Indian capital markets in October, the highest in seven months, buoyed by RBI's rate cut and positive macroeconomic numbers. Most of the fresh capital has been infused in the debt market. The net inflow in equities stood at `6,650 crore last month, while it was Rs 15,700 crore for debt. This is the highest investment by FPIs since March when they had poured in `20,723 crore into Indian markets.
