US regulators are likely to order JPMorgan Chase & Co. to correct lapses in how it polices suspect money flows, in an action expected as soon as Friday. The order would be the latest action that US regulators have taken this year to force banks to tighten their anti money- laundering systems, which are supposed to flag suspect transactions from sanctioned countries or those from customers with ties to drug trafficking or terrorism.

The action would be in the form of a cease-and-desist order, which regulators use to force banks to improve compliance weaknesses, the sources said. The Office of the Comptroller of the Currency and the Federal Reserve are expected to issue the order. J.P. Morgan will probably not have to pay a monetary penalty, according to one person familiar with the situation.

The Treasury Department's anti money-laundering unit, the Financial Crimes Enforcement Network, also could take a separate action against the bank.
