Today's Wall Street Journal features "Study Casts Doubt on Key Rate", which alleges that banks may have reported bad data for LIBOR calculations. "That has led Libor, which is supposed to reflect the average rate at which banks lend to each other, to act as if the banking system was doing better than it was at critical junctures in the financial crisis. The reliability of Libor is crucial to consumers and businesses around the world, because the benchmark is used by lenders to set interest rates on everything from home mortgages to corporate loans," says the Journal. It adds, "Faced with suspicions by some bankers that their rivals have been low-balling their borrowing rates to avoid looking desperate for cash, the British Bankers' Association, which oversees Libor, is expected to report Friday on possible adjustments to the system."
