A level above 70 suggests to some traders the Southeast Asian currency was oversold and poised to change direction.
The baht climbed 0.3% to 31.985 per dollar as of 9.32am in Bangkok from Dec 9, according to data compiled by Bloomberg. The currency reached 31.95 earlier, the strongest level since Nov 25, and has rallied 0.9% in a week. Onshore markets were closed on Tuesday for a public holiday.
"The baht got some boost as the tension eased in the very short term due to the dissolution of parliament," said Toru Nishihama, an economist covering emerging markets at Dai-ichi Life Research Institute Inc in Tokyo.

One-month implied volatility, a measure of expected moves in the exchange rate used to price options, declined three basis points, or 0.03 percentage point, to 6.78%.
