LONDON (MarketWatch) -- The three-month U.S. dollar London interbank offered rate, or Libor, topped 0.5% Monday for the first time since July 2009. The rate was fixed Monday at 0.5097%, up from 0.4969% on Friday. The spread between dollar Libor and overnight index swaps, a measure of banks' reluctance to lend to each other, widened on Monday, analysts said. Worries over strains in the banking system have been on the rise in recent weeks amid concerns over euro-zone sovereign debt.
