(Reuters) - Nigeria's naira slumped 23 percent against the U.S. dollar on Monday in tentative interbank trading after central bank removed its currency peg, Thomson Reuters data showed.The naira traded just twice at 255 against the dollar, and less than $1 million had changed hands by 11:00 a.m. (1000 GMT), as dealers said they were nervous about foreign exchange liquidity under the new system.
Monday's rate was sharply weaker than the 197 peg the central bank had been maintaining for the past 16 months, then abandoned last week in a bid to alleviate chronic forex shortages.
