Till now, the limit for such investment was $15 billion in corporate debt, with an additional limit of $5 billion in bonds with a residual maturity of over five years.
This additional limit has been raised to $25 billion, taking the maximum limit of FII investment in bonds and non-convertible debentures issued by infrastructure companies to $40 billion, RBI said.
The apex bank added that such investments by FIIs would have a minimum lock-in period of three years.
However, the FIIs can trade among themselves during the lock-in period.
The relaxation in the limit comes at a time when the government has announced plans to double investments in the infrastructure sector to $1 trillion during the 12th Plan (2012-17).
