This weekend's Wall Street Journal featured a brief entitled, "Libor's Climb Past 2% is Unnerving Some Investors." They write, "A benchmark used to set borrowing costs on trillions of dollars worth of loans is on the rise, stirring concerns about the effect of higher U.S. interest rates on consumers and businesses. The three-month U.S. dollar London Interbank Offered Rate, or Libor, surpassed 2% this week for the first time since 2008. That will lift rates on more than $100 trillion in debt and derivative contracts that are linked to the U.S. benchmark, from business and student loans to home mortgages." The piece explains, "Libor has been rising for the last two years as the Federal Reserve has tightened interest rates. But gains have accelerated in recent months, according to RBC Capital Markets strategist Michael Cloherty, because of changes to the U.S. tax code that have encouraged companies to reshuffle bond holdings. One recent source of worry among strategists and investors has been the growing gap between Libor, which is set amongst banks, and the overnight index swap rate, which is determined by central bank rates. That spread has widened sharply recently and this week was at its highest level since 2009. Back then, the sudden widening in the Libor-OIS spread signaled mounting stress within the financial system as a liquidity crunch made it more expensive for banks to lend to each other."
