Thailand's central bank raised its key interest rate for a second straight meeting on Wednesday, by a quarter point as expected, to tame multi-year high inflation and ensure a continued economic recovery.

The Bank of Thailand's (BOT) monetary policy committee voted unanimously to increase the one-day repurchase rate to 1.00%.

Of 25 economists surveyed by Reuters, 22 had expected a quarter-point hike and three predicted a half-point increase. (Reporting by Orathai Sriring, Kitiphong Thaichareon, Satawasin Staporncharnchai and Chayut Setboonsarng; Editing by Martin Petty)
