* Senate panel: HSBC allowed shadowy funds to move globally
* Report cites problems at bank and its U.S. regulator
* Bank compliance staff overwhelmed - report
* Senator Levin says HSBC culture was "polluted"
By Carrick Mollenkamp
WASHINGTON, July 16 (Reuters) - A "pervasively polluted" culture at HSBC Holdings Plc allowed the bank to act as financier to clients seeking to route shadowy funds from the world's most dangerous and secretive corners, including Mexico, Iran, the Cayman Islands, Saudi Arabia and Syria, according to a scathing U.S. Senate report issued on Monday.
While the big British bank's problems have been known for nearly a decade, the Senate probe detailed just how sweeping the problems have been, both at the bank and at the Office of the Comptroller of the Currency, a top U.S. bank regulator which the report said failed to properly monitor HSBC.
"The culture at HSBC was pervasively polluted for a long time," said Senator Carl Levin, chairman of the U.S. Senate Permanent Subcommittee on Investigations, a Congressional watchdog panel.
The report comes at a troubling time for a banking industry reeling from a multi-country probe into the manipulation of global benchmark rates. Last month, rival British bank Barclays Plc agreed to pay a $453 million fine to settle a U.S.-British probe into the rigging of the benchmark interest rate known as the London interbank offered rate, or Libor.
The Senate probe provides a rare look at how HSBC responded when confronted with numerous cases of suspect money flows.
The report caps a year-long inquiry that included a review of 1.4 million documents and interviews with 75 HSBC officials and bank regulators. It will be the focus of a hearing on Tuesday at which HSBC and OCC officials are scheduled to testify.
The bank and the regulator are expected to face tough questions at the hearing about how the abuses were allowed to continue, even after the OCC took regulatory action against HSBC in 2010. A Reuters investigation found persistent lapses in the bank's anti-money laundering compliance since 2010.
In an emailed statement, HSBC said the Senate report had provided "important lessons for the whole industry in seeking to prevent illicit actors entering the global financial system".
The bank said it is spending more money on compliance and has become more coordinated in policing high-risk transactions.
The report also contained strong criticism of the OCC, saying the regulator failed to crack down on the bank despite multiple red flags, allowing money laundering issues "to accumulate into a massive problem".
Thomas Curry, who took over as comptroller less than four months ago, said in a statement on Monday that anti-money laundering compliance "is crucial to our nation's efforts to combat criminal activity and terrorism, and the OCC expects national banks and federal thrifts to have programs in place to effectively comply with these laws".
Curry said the Senate report had made a number of "thoughtful" recommendations, "which we fully embrace".
The failings and lax controls inside HSBC included an inability to properly monitor $15 billion in bulk cash transactions between mid-2006 and mid-2009, inadequate staffing and high turnover in the bank's compliance units, the report said.
HSBC ignored risks in doing business in countries such as Mexico, a country rife with drug trafficking, it said.
Between 2007 and 2008, HSBC's Mexican operations moved $7 billion into the bank's U.S. operations. According to the report, both Mexican and U.S. authorities warned HSBC that the amount of money could only have reached such a level if it was tied to illegal narcotics proceeds.
The Senate probe also examined banking HSBC did in Saudi Arabia with Al Rajhi Bank, which the report said has links to financing terrorism. Evidence of those links emerged after the Sept 11, 2001 attacks on the United States, the Senate report said, citing U.S. government reports, criminal and civil legal proceedings and media reports.
In 2004, Al Rajhi sued the Wall Street Journal, which had published an article about U.S. and Saudi authorities monitoring accounts. The article referenced Al Rajhi.
Al Rajhi said in response to a WSJ story that it "unequivocally condemns terrorism". Al Rajhi and the paper settled in 2004. The paper did not pay damages and stated that it "did not intend to imply an allegation that (Al Rajhi) supported terrorist activity, or had engaged in the financing of terrorism", the Senate report said.
In 2005, HSBC told its affiliates to no longer do business with the bank, the report said. Four months later, HSBC officials reversed course, allowing affiliates to decide whether to continue to do business with Al Rajhi.
A Middle Eastern unit of HSBC continued doing business with the bank, the report said. HSBC ultimately stopped helping the bank handle certain types of transactions, and HSBC compliance officials rebuffed other HSBC bankers seeking to maintain ties to the bank.
Then in late 2006, Al Rajhi threatened to yank all of its business with HSBC unless it regained access to using HSBC's bulk-cash transaction business, the Senate report said. HSBC agreed to continue to provide the bank bulk shipments of U.S. dollars until 2010 when HSBC exited entirely the bulk-cash business.
Officials at Al Rajhi could not immediately be reached for comment.
The focus of the Senate probe was HSBC's U.S. operations, which has its main office in New York. HSBC used the U.S. unit as a selling point to clients outside the United States, touting its ability to handle U.S. dollar transactions.
Among HSBC's problems, the report described the bank's compliance division as unable to battle the suspect money. High turnover of top compliance officials made it difficult for reform to take hold, the report said. Employees were "overwhelmed" by a mounting number of suspect transactions that needed review.
"We're strapped and getting behind in investigations," one bank official wrote in June 2008. By that time, HSBC was cutting costs to offset losses tied to subprime home loans and the brewing financial crisis. In 2010, one disgusted top compliance official threw up his hands and quit after less than a year on the job, according to the report.
Typical of the problems inside the bank were transactions tied to Mexico, a country the report said is "under siege from drug crime, violence and money laundering".
HSBC, according to the report, helped move money for a Mexican foreign-exchange dealer called Casa de Cambio Puebla that served as a hub for laundered proceeds, according to the report.
Between 2005 and 2007, there was a "growing flood" of U.S. dollars moving between the exchange house and HSBC, setting off red flags inside HSBC. Some bankers said the transfers were legal. One said the money came from Mexican landscapers working in the United States and routing money back home to their families.
HSBC ultimately closed the account in November 2007 after it received a seizure warrant from the Mexican attorney general seeking money tied to the exchange dealer, the Senate report said.
Some of the money that moved through HSBC was tied to Iran, the report said, which would violate U.S. prohibitions on transactions linked to it and other sanctioned countries.
To conceal the transactions, HSBC affiliates used a method called "stripping", where references to Iran are deleted from records. HSBC affiliates also characterized the transactions as transfers between banks without disclosing the tie to Iran in what the Senate report called a "cover payment".
HSBC "failed to take decisive action to confront these affiliates and put an end to the conduct," the report said.
Between 2001 and 2007, more than 28,000 transactions were identified by an outside auditor for HSBC that potentially could have run afoul of laws that prohibit transactions with sanctioned countries. Of those, 25,000 involved Iran. A smaller number required additional analysis to determine if violations of U.S. regulations had occurred, the report said.
At the heart of HSBC's failings was the fact that it served as a hub for smaller financial firms needing access to the global banking system, the report said.
In one example detailed in the Senate investigation, HSBC continued to do business with one client that admitted to U.S. law enforcement that it had failed to maintain an effective anti-money laundering system.
The client, Sigue Corp, was a money processor in California, the report said. In 2008, the company agreed to a so-called deferred prosecution with the U.S. Justice Department and other U.S. agencies where it admitted to allowing millions of dollars of suspect transactions between 2003 and 2005. Undercover U.S. officers, in a sting, even moved money through the company, explicitly telling Sigue agents they were moving illegal drug proceeds, the report said.
A day after the agreement was announced, David Bagley, the head of HSBC compliance, sent a handwritten note to another bank official, asking, "Obvious question--I assume they are not our customer." Bagley is scheduled to testify on Tuesday at the Senate hearing.
In fact, Sigue was an HSBC customer, and bank officials internally discussed whether to close the account. One compliance official recommended it should be shut down. In the end, the bank kept doing business with Sigue.
In 2009, the Justice Department said Sigue had satisfied the requirements of the agreement and a criminal case was dismissed.
