The Reserve Bank of India (RBI) on Wednesday revised the way banks calculate and report their foreign exchange exposures. The revised rules do away with the separate calculation of onshore and offshore net open positions (NOP), allow banks to include accumulated surpluses from overseas operations in NOP calculations, require forex risk capital charges to be maintained against actual NOP, and modify the shorthand method for measuring exposure by treating gold positions separately. The central bank has also allowed certain structural foreign exchange positions to be exempted from NOP calculations. Market participants said that the exemptions will create room for additional positions and improve trading capacity for banks.
