Foreign diplomats have complained to the US government about the decision of several US banks to end services for diplomatic missions.
The diplomats of several countries said they were actively searching for new banks but were having little success.
Federal officials heard the concerns of roughly 150 envoys during a closed-door briefing on Thursday at the United Nations in New York City.
Some diplomats said the UN budget could be affected by the account closures.
The Wall Street Journal newspaper suggested in November that the banks' decisions were prompted by difficulties in adhering to federal money-laundering regulations affecting international transfers.
Regulations have been tightened since 9/11 in an effort to stop the flow of illegal foreign funds for crimes like financing terrorist acts. BBC News
