Central bank sells longer bonds to reduce instability
20/03/2012
The Bank of Thailand is issuing bonds with longer maturities to reduce local market volatility caused by foreign capital inflows.
Pongpen Ruengvirayudh, assistant governor of the bank's Financial Markets Operations Group, said the central bank has been selling bonds over the past year with longer maturities, ranging from about six months to three years.
The baht strengthened to 30.69 to a US dollar yesterday from 30.73 on Friday, a 0.13% rise. Ms Pongpen said the central bank has not been intervening in the market very much recently.
"A gradual appreciation of the baht is positive for the economy when energy prices are rising," she said.
Ms Pongpen added that a lessening of market concerns about Europe's sovereign debt crisis following the Greek debt restructuring agreement has resulted in a return of foreign capital to the region.
Foreign investors arbitraging interest rate differences between overseas and local markets and buying Thai stocks and bonds has led to the baht's appreciation. The central bank does not believe the short-term investment inflows are excessively speculative.
"We do not consider the inflows hot money. Investors normally look for short-term investments during times of high global uncertainty and fast-changing news," she said.
