The fraud office said that it had charged Barclays, John S. Varley, its former chief executive, and the former bankers Roger A. Jenkins, Thomas L. Kalaris and Richard W. Boath with conspiracy to commit fraud by false representation related to the June 2008 fund-raising.
Barclays and Mr. Varley and Mr. Jenkins were also charged with providing unlawful financial assistance.
The former executives could not immediately be reached for comment on Tuesday. They are expected to appear in Westminster Magistrates’ Court in London next month.
“Barclays is considering its position in relation to these developments,” the bank said in a news release.
Mr. Jenkins, 61, is the former executive chairman of investment banking and investment management in the Middle East and North Africa at Barclays Capital. He helped arrange the fund-raising.
Mr. Kalaris, 61, is the former chief executive of Barclays Wealth and Investment Management. Mr. Boath, 58, is the former European head of Barclays’ Financial Institutions Group.
Barclays said that the fraud office had informed the bank that it had not decided whether it would also bring charges against Barclays Bank P.L.C., an operating unit, with respect to the loan.
The inquiry into the fund-raising is one of a number of regulatory issues that have bedeviled Barclays in recent years. In 2012, a scandal over the manipulation of an important benchmark interest rate, Libor, or the London interbank offered rate, shook the bank to its core. Barclays paid $450 million in penalties, and its American chief executive, Robert E. Diamond Jr., resigned.
The bank’s current chief, James E. Staley, also an American, has been seeking to move the bank past its regulatory burdens and to turn its business around since joining in December 2015. He has moved aggressively to sell off businesses the bank does not consider core operations and resolve legacy misconduct issues that have dragged on its results.
