The probe of Libor manipulation is proving to be the tip of the iceberg as inquiries into assets from derivatives to foreign exchange show that if there’s a chance to rig benchmark rates in world markets, someone is usually willing to try.
Singapore’s monetary authority last week censured 20 banks for attempting to fix interest rate levels in the island state and ordered them to set aside as much as $9.6 billion. Britain’s markets regulator is looking into the $4.7 trillion-a-day currency market after Bloomberg News reported that traders have manipulated key rates for more than a decade, citing five dealers.
“It’s happened time and again: all of these markets have been influenced by major market-makers, which is a polite way of saying they’ve been rigged,” Charles Geisst, a finance professor at Manhattan College in Riverdale, New York, said in a telephone interview.
While the indexes under scrutiny are little known to the public, their influence extends to trillions of dollars in securities and derivatives. Barclays Plc (BARC), UBS AG and Royal Bank of Scotland Group Plc have been fined about $2.5 billion in the past year for distorting the London interbank offered rate, which is tied to $300 trillion worth of securities. Regulators are also probing ISDAfix, a measure used in the $370 trillion interest-rate swaps market, as well as how some oil products prices are set.
