COLOMBO (Reuters) - Sri Lanka’s central bank is expected to leave its key interest rates unchanged on Friday, a Reuters poll showed, but a surprise rate cut is not ruled out due to sluggish economic growth ahead of a presidential election later this year.

Ten out of 12 economists surveyed expected the Central Bank of Sri Lanka to keep both its standing deposit facility rate (SDFR) and standing lending facility rate (SLFR) steady at7.50% and 8.50%, respectively. One analyst expected both rates to be cut by 50 basispoints (bps) and one by 25 bps. Seven out of the 12 analysts expect the central bank to cut the rates by 50 bps before the end of this year. All of the analysts predicted the statutory reserve ratio(SRR) would be kept at 5.00%.

“Some rates have come down since the last rate cut, but we are yet to see the full impact of it,” said Shiran Fernando, the chief economist at Ceylon Chamber of Commerce.

Others said a rate cut would put more pressure on the rupee currency LKR=LK as it could result in heavy foreign outflow from government bonds.

However, one economist, who expects a 25 bps cut, said the government has to show some progress on economic growth before a presidential election that must be held by Dec. 9.

“The last rate cut has failed to boost the credit and economic growth. Bad loans are also on the rise. If the country has to see some growth, a rate cut is needed now,” the Colombo- based analyst said, asking not to be named as he is not authorized to talk to media.

The central bank cut rates by 50 basis points in May to support the economy.

Economic growth had already slowed to a 17-year low of 3.2%in 2018 and the central bank expects it to slow to 3% or less this year, while a Reuters poll has predicted growth will be its lowest in nearly two decades this year.
