In Part 1, we examined the baht paradox: strong yet volatile, acting more like a safe-haven currency than a growth currency. Now we turn to the lever central banks are supposed to control — interest rates.
The Policy Rate Story (2005–2025)
Over the past two decades, the Bank of Thailand has swung policy rates through sharp cycles — yet the baht rarely followed the script.
2005–2008 (Stop–Go tightening): Rates surged from 2.25% to 5%, then quickly reversed. The baht held steady.
2008–2011 (Crisis & rebound): Aggressive cuts during the Global Financial Crisis (down to 1.25%) were followed by swift hikes back to 3.5%. Still, the baht stayed resilient.
2011–2019 (Long easing trend): Rates slid from 3.5% to 1.5%, with only one small hike in 2018–19. Instead of weakening, the baht appreciated strongly, hitting multi-year highs.
2019–2022 (Covid shock): Policy cut to a record-low 0.5%. After a brief dip, the baht firmed again.
2022–24 (Inflation hikes): Rates rose back to 2.5%. Far from weakening, the baht drew renewed capital inflows.
2024–25 (New easing cycle): Since late 2024, rates have trended down toward 1.75%. If history is a guide, the baht is unlikely to weaken much.
But the real picture emerges when you place these rate moves next to the baht itself…
