Cross border bank investment limits increased, allowing greater overseas investments and borrowings subject to ratings, board approval and ALM discipline. Banks may invest in overseas money market and debt instruments up to twenty five per cent of unimpaired Tier I capital or the equivalent baseline amount, and may place undeployed FCNR(B) funds in long term fixed income securities provided instruments meet prescribed credit ratings, board approved type/maturity and overall caps, maturities do not exceed underlying FCNR(B) deposit maturities, and all investments comply with gap discipline and risk management/ALM guidelines; borrowings from head offices and overseas correspondents are permitted to the same revised ceiling.
