Quick answer
The Bank of Thailand runs flexible inflation targeting with a headline target of 1% to 3% and uses the 1-day bilateral repurchase rate as its policy rate. It raised that rate to 2.50% by September 2023 and has cut six times since October 2024. The policy rate has been 1.00% since 25 February 2026, with headline inflation at 2.53% and core inflation at 1.44% in August 2026.

BoT policy snapshot
The settings below come from the Bank of Thailand and official statistics as stored on the Thailand data page. Each figure carries its own date, because a rate, an inflation print and an exchange rate taken from different points in the cycle give a misleading picture.
| Measure | Latest | As of |
|---|---|---|
| Policy rate | 1.00% | Since 25 February 2026 |
| Consumer price inflation | 2.53% | August 2026, annual |
| Core inflation | 1.44% | August 2026, annual |
| Real policy rate | -1.53 pp | Policy rate less inflation |
| 10-year government yield | 2.39% | 2 October 2026 |
| USD/THB | 33.59 | 2 October 2026 |
Mandate and instruments
The Bank of Thailand has used flexible inflation targeting since 2000. The target, currently headline inflation of 1% to 3% over the medium term, is agreed each year between the Monetary Policy Committee and the Minister of Finance. When inflation leaves the range the Committee writes an open letter explaining why and how it expects inflation to return.
The Committee has seven members and meets six times a year. The policy rate is the 1-day bilateral repurchase rate, which anchors overnight money-market rates. The framework is explicitly flexible: the Committee weighs growth and financial stability, including Thailand's high household debt, alongside inflation.
The Bank publishes a Monetary Policy Report each quarter and edited minutes after each meeting, which together give the clearest view of how the Committee is balancing those three objectives.
A shallow cycle by global standards
Thailand's rate cycle was small. The policy rate fell to 0.50% in May 2020, rose in eight steps of 25 basis points from August 2022, and peaked at 2.50% on 27 September 2023. Headline inflation peaked at 7.86% in August 2022 and fell back quickly.
Cuts began on 16 October 2024. Six reductions have taken the rate to 1.00%, where it has been since 25 February 2026. Headline inflation was below zero from April 2025 to March 2026, which meant real rates stayed positive even as nominal rates fell.
The picture changed in the second quarter of 2026. Headline inflation moved from slightly negative in March to 2.89% in April and was 2.53% in August, back inside the target range, while core inflation was 1.44%. With the policy rate at 1.00%, the real policy rate on a headline basis is now negative.
Policy rate and inflation
The 1-day bilateral repurchase rate (percent) against annual consumer price inflation (percent), 2019 to 2026.
Takeaway: The whole cycle spanned two percentage points, and inflation has swung much further than the policy rate throughout.
The real policy rate
Subtracting inflation from the policy rate gives a simple measure of how restrictive policy is. It is backward-looking, because it uses realised rather than expected inflation, but it is transparent and comparable across countries.
Real policy rate
Policy rate in force at month end less annual consumer price inflation, percentage points.
Takeaway: The real policy rate stayed positive while inflation was below zero from April 2025 to March 2026, then turned negative when inflation rebounded: -1.53 percentage points in August 2026.
How Bank of Thailand policy reaches the baht
The baht is a managed float, and the rate differential is only one of its drivers. Thailand normally runs a current account surplus built on tourism receipts and manufactured exports, so the tourist season and global trade conditions feed directly into currency demand. Thailand is also a large gold-trading centre, and gold price swings produce baht flows that have little to do with monetary policy.
The Bank smooths excessive volatility rather than defending a level, and it has encouraged outward investment and foreign-currency deposits to reduce one-way appreciation pressure. USD/THB was about 32.59 at the start of October 2024 and about 33.59 two years later, a modest depreciation over a period in which the policy rate was cut by 150 basis points.
The USD/THB dashboard puts the exchange rate beside the rate differential and the release calendar for both economies.
A decision-day workflow
- Note the decision and the vote split, which the Bank publishes with each announcement.
- Compare headline and core inflation with the 1% to 3% target; the gap between them matters.
- Check the growth forecast in the Monetary Policy Report against the previous one.
- Track tourism arrivals and the trade balance for the baht's non-rate drivers.
- Watch the 10-year government yield against the policy rate for the market's view of the path.
