The Southeast Asian country's worst coronavirus outbreak led to restrictions in July and August that hit economic activity, but the curbs have since been eased https://www.reuters.com/article/idUSL1N2Q006L and Thailand will soon reopen to more vaccinated visitors.

The government also recently lifted the public debt ceiling for more fiscal flexibility to fight the outbreak, while the Bank of Thailand (BOT) governor on Monday said the central bank was ready to introduce measures as needed.

In the poll, 20 of 23 economists expect the BOT's Monetary Policy Committee (MPC) to hold the one-day repurchase rate at 0.50% this week to preserve limited policy ammunition.

Three economists predicted a quarter-point cut, citing weak growth and the MPC's split decision at the August meeting, when it cut the 2021 growth forecast https://www.reuters.com/article/idUSL4N2PA3QW to 0.7% from 1.8%.

The BOT will give a new forecast on Wednesday. Governor Sethaput Suthiwartnarueput said on Monday growth might not reach 1% this year.

Last month, Sethaput told Reuters interest rates were a blunt tool, while Somchai Jitsuchon, a non-central banker on the MPC, also told Reuters that lower rates would not help much.

The last meeting's split vote raised a 30% chance of a rate cut "but the economy has since improved so the BOT may save its ammunition for the worst case", said Panundorn Aruneeniramarn, an economist at Siam Commercial Bank.

While predicting no rate change this week, Kobsidthi Silpachai, head of capital markets research at Kasikornbank, said: "We can still expect dissensions within the committee as economic conditions have not shown marked improvement."

However, Gareth Leather, economist at Capital Economics, predicted a quarter-point rate cut this week, citing an economy "in the doldrums" and concern about deflation.
