A committee set up by the British Treasury to choose a new administrator for LIBOR gave the job to NYSE Euronext, which operates the New York Stock Exchange. It is paying a token $1.50 for the honor and expects to start managing the international benchmark interest rate early next year. The British Bankers' Association has overseen LIBOR since the 1980s, but the scandal surrounding the manipulation of the rate by traders dented its reputation.

The global asset-management industry grew to a record $62.4 trillion last year, according to the Boston Consulting Group, passing the previous high set in 2007, before the financial crisis.

Political economy

The IMF shaved its forecast of growth for the world economy from a previous estimate in April. It lowered its projections for this year in America, the eurozone, China, Brazil, Russia and India, though Britain, Canada and Japan all had their GDP growth figures revised up.

The man who was in charge of Japan's Fukushima nuclear plant when it was hit by a tsunami in March 2011 died of esophageal cancer.
