As big banks face the fallout from a global investigation into interest rate manipulation, American and British lawmakers are scrutinizing regulators who failed to take action that might have prevented years of illegal activity.
Politicians in both London and Washington are questioning whether regulators allowed banks to report false rates in the run-up to the 2008 financial crisis and afterward. On Monday, Congress stepped into the fray, requesting information about the role of the Federal Reserve Bank of New York, according to people close to the matter.
The focus on regulators and other financial institutions has intensified in the last two weeks after the British bank Barclays agreed to pay $450 million to resolve its case. British and American authorities accused the bank of improperly influencing key interest rates to deflect concerns about its health and bolster profits.
The Barclays settlement is the first action stemming from a broad investigation into how banks set key benchmarks, including the London interbank offered rate, or Libor. The pricing of $350 trillion of financial products, including credit cards, mortgages and student loans, is pegged to Libor and other such rates.
Authorities around the world are now considering action against more than 10 big banks, including UBS,JPMorgan and Citigroup.
The banks also face a raft of civil litigation from municipalities, investors and other financial firms that claim they lost money from the misreporting of rates. These lawsuits could end up costing the industry tens of billions of dollars, according to analysts.
On Monday, the oversight panel of the House Financial Services Committee sent a letter to the New York Fed seeking transcripts from at least a dozen phone calls in 2007 and 2008 between central bank officials and executives at Barclays.
“Some news reports indicate that although Barclays raised concerns multiple times with American and British authorities about discrepancies over how Libor was set, the bank was not told to stop the practice,” Representative Randy Neugebauer, a Texas Republican and the head of the House oversight panel, said in the letter, which was reviewed by The New York Times.
The political firestorm also escalated in London on Monday, where a British parliamentary committee grilled a top Bank of England official over his knowledge of wrongdoing at Barclays. British politicians chided Paul Tucker, deputy governor at the Bank of England, the country’s central bank, for not taking a more active role in Libor.
In November 2007, Mr. Tucker led a meeting in which some officials raised concerns that banks were underreporting Libor submissions to temper concerns about their health, a process known as lowballing. It was in the earliest stages of the market turmoil that would culminate in the 2008 financial crisis, and banks were loath to report high rates that pointed to weak financial footing.
“This doesn’t look good, Mr. Tucker,” Andrew Tyrie, the head of the parliamentary committee, said on Monday, referring to minutes of the meeting. “We have what appear to any reasonable person as the lowballing of rates.”
The Barclays settlement with the Commodity Futures Trading Commission, Justice Department and Financial Services Authority of Britain has been a black mark for the bank. The scandal has already prompted the resignation of the bank’s chairman, Marcus Agius; its chief executive, Robert Diamond; and a top deputy, Jerry del Missier.
As it tries to control the damage, Barclays is framing a defense around the notion that regulators approved the actions. Last week, the bank released information about dozens of conversations with the Bank of England, the New York Fed and other government agencies.
In one call with the Financial Services Authority, a Barclays manager acknowledged that the bank was understating its Libor submissions. “So, to the extent that, um, the Libors have been understated, are we guilty of being part of the pack? You could say we are,” the Barclays manager said, according to regulatory documents.
The bank also discussed its Libor rates twice with the Bank of England in fall 2008, according to documents Barclays released last week. Additional evidence has emerged that the British central bank first held discussions about Libor with Mr. del Missier a year earlier, in late 2007, said a person briefed on the matter, who spoke on condition of anonymity.
Authorities are also focused on Barclays’ conversations with the New York Fed, including discussions between senior bank employees and officials from the Fed’s trading desk, according to another person briefed on the matter, who also requested anonymity.
In the letter to the New York Fed, Mr. Neugebauer requested transcripts of the calls by Friday.
“The role of the government is to ensure that our capital markets are run with the highest standards of honesty, integrity and transparency” Mr. Neugebauer said on Monday.
“The interest rate manipulation scandal clearly demonstrates that these principles were violated by Barclays and, from what we understand, other banks as well. My request to the New York Fed is a preliminary step to understanding what role, if any, the regulators played in this scandal.”
In a statement, a New York Fed spokeswoman said that during the financial crisis “we received occasional anecdotal reports from Barclays of problems with Libor.” Ultimately, the New York Fed made “further inquiry of Barclays as to how Libor submissions were being conducted” and offered “suggestions for reform of Libor” to British authorities.
Under sharp questioning by British political leaders on Monday, Mr. Tucker, considered a front-runner to succeed Mervyn A. King as the next head of the Bank of England, defended the central bank and his professional future. Committee members focused their questioning on a conversation that Mr. Tucker had with Mr. Diamond in October 2008.
According to an e-mail trail, Mr. Tucker contacted Mr. Diamond, saying he was “struck” that Barclays was paying a high interest rate on its loans.
Mr. Tucker testified that his conversations with Mr. Diamond were meant to convey that the financial markets were questioning whether the British bank had access to capital.
Barclays last week also released documents saying that at least some bank executives believed Mr. Tucker had instructed them to lower the Libor submissions. That belief, some regulators say, stemmed from a “miscommunication,” rather than instructions from Mr. Tucker. The bank also never explicitly told regulators that it was reporting false interest rates that amounted to manipulation, according to regulatory documents.
Mr. Tucker on Monday flatly denied that he authorized, or even knew about, any improper actions. “We were not aware of it, other than what is starting to come out in these investigations,” he said.
Underscoring the point, he noted that the Bank of England used the rate to set its Special Liquidity Scheme, in which the government lent local banks more than $310 billion from 2008 to 2011.
Still, British politicians criticized Mr. Tucker for not taking a more active role in policing the banks. When asked whether he was confident that the Libor manipulation had stopped, Mr. Tucker wavered.
“I can’t be confident about anything after learning about this cesspit,” he replied.
