``There are still some complications that need clarification before this facility is restored to these two banks,'' said a central bank official.

The banks which have restored the facility are ABN Amro Bank, ANZ Grindlays Bank, Bank of America, Banque National De Paris, Banque Indosuez (Now Credit Agricole Indosuez), Citibank, Deutsche Bank, Hong Kong Bank, Oman International Bank and Standard Chartered Bank.

Twelve foreign banks were involved in the irregular securities transactions of 1992. These banks had violated the RBI guidelines and instructions on certain types of transactions, portfolio management scheme and ready-forward transactions.

After issuing show-cause notices to nine foreign banks, the RBI had imposedpenalties on them depending on the seriousness of the violations.

Besides imposing pecuniary penalties on the nine banks, exemption granted to banks from maintenance of the incremental cash reserve ratio was withdrawn in case of all 12 banks on account of various other lapses in observance of the regulatory framework.

The central bank had allowed remittance of profit by some foreign banks only after the penalties were paid by them.

Some of the banks did not seek permission to remit profit for augmenting capital adequacy requirements.

Among the scam-tainted banks, the US-based Citibank had paid the highest amount of penalty of above Rs 50 crore. Standard Chartered Bank had paid above Rs 36 crore while Hong Kong Bank paid above Rs 17 crore.
