ISTANBUL, May 7 (Reuters) - The Turkish central bank moved to shore up the lira on Monday after the currency fell to record lows against the dollar, lowering the upper limit for foreign exchange which banks can use for their reserve requirements.
The lira, which has weakened 11 percent against the U.S. currency this year, trimmed its losses after the announcement, rebounding to 4.25 against the dollar from a morning low of 4.2715. It hit a low of 4.2901 on Friday.
Concerns about the central bank’s ability to rein in double-digit inflation have driven the lira losses, with snap elections called for June 24 generating political uncertainty.
“The upper limit for the FX maintenance facility within the reserve options mechanism has been lowered to 45 percent from 55 percent,” the central bank said.
Some 6.4 billion Turkish lira ($1.5 billion) of liquidity will be withdrawn from the market and approximately 2.2 billion U.S. dollars of liquidity will be provided to banks, it said.
Muammer Komurcuoglu of Is Invest said he saw the move as a step towards decreasing lira depreciation.
“We think that the central bank is trying to buy time until the next rate setting meeting on June 7. We don’t think the move will have a significant, lasting impact on the market,” he said.
The reserve options mechanism allows banks to keep a certain ratio of their Turkish lira reserve requirements in foreign exchange and/or gold. ($1 = 4.2497 liras) (Writing by Daren Butler; Editing by David Dolan)
