A bank may establish a multinational operation for the reason of retail defensive strategy. The underlying rationale being that

		by maintaining foreign branches and foreign currency balances, banks may reduce transaction costs and foreign exchange risk on currency conversion if government controls can be circumvented.
		banks follow their multinational customers abroad to prevent the erosion of their clientele to foreign banks seeking to service the multinational's foreign subsidiaries.
		multinational banks are often not subject to the same regulations as domestic banks. There may be reduced need to publish adequate financial information, lack of required deposit insurance and reserve requirements on foreign currency deposits, and the absence of territorial restrictions.
		multinational banking operations help a bank prevent the erosion of its traveler's check, tourist, and foreign business markets from foreign bank competition.
