NEW YORK (MarketWatch) -- U.S. regulators may announce enforcement actions against J.P. Morgan Chase & Co. /quotes/zigman/272085/quotes/nls/jpm JPM +2.61% as early as Monday for alleged lapses in risk management and money-laundering controls, according to a report in The Wall Street Journal citing unnamed people familiar with the bank's talks with regulators. The Office of the Comptroller of the Currency (OCC) will ask J.P. Morgan Chase to remedy problems that led to a small group of London traders to accumulate more than $6 billion in losses in 2012, the report said. Another OCC action will require the bank to improve its anti-money laundering procedures, the report said. The latter action is similar to an order against Citigroup Inc. /quotes/zigman/5065548/quotes/nls/c C +1.66% last year to upgrade its monitoring procedures and internal audits, the report said. The bank's board of directors is expected to receive the report this week, the newspaper reported. Shares of J.P. Morgan, which is a component of the Dow Jones Industrial Average , fell 0.7% in midday trades.
