If the deal goes ahead it will join the other big out-of-court settlement - the $1.8bn compensation package for customers - following the 1991 closure of BCCI after years of multi-million dollar fraud.
The compensation deal, partly funded by BCCI's majority shareholder Abu Dhabi, gained court clearance on 31 January. The Saudi deal with NCB, its former chief operating officer, Sheikh Khalid bin Mahfouz, and an associate, the Pakistani banker Haroon Khalon, would settle allegations that they were involved in covering up the BCCI scandal.
The defendants have agreed to pay into the settlement without admitting liability and to drop counter claims against BCCI.
The liquidators would then drop a $10.5bn lawsuit filed earlier against Sheikh Mahfouz and NCB, a former customer and investor in BCCI.
