In Part 2, we saw how Thailand’s policy rate lost traction: cutting didn’t weaken the baht, hiking only attracted more inflows.
Now we turn to the market’s view — bond yields.
For two decades, the 10-year Thai government bond yield has moved steadily downward, detached from growth or inflation fundamentals. Yields became the market’s true compass, signaling stability and reinforcing the baht’s safe-haven status.
The Yield Story (2005–2025)
2005–2008: Yields fluctuated near 5–6% before the Global Financial Crisis.
2009–2012: Post-GFC compression toward 3%, even as policy rates rebounded.
2013–2019: Despite political upheaval, yields drifted lower into the 2.5–3.0% range.
2020 (Covid shock): Collapsed to record lows near 1%.
2021–22: Temporary rebound above 3% during global inflation scare.
2023–25: Renewed slide below 3%, even as domestic growth remains weak.

Why Fundamentals Don’t Drive Yields
In textbook finance, long-term yields should reflect:
inflation expectations,
fiscal balance, and
growth potential.
But in Thailand, other forces dominated:
Persistent foreign inflows: Bonds treated as safe-haven assets.
Low sovereign risk: Strong reserves and low external debt kept spreads tight.
Policy irrelevance: With interest rates sidelined, markets dictated conditions through yields.
The Paradox: A Reinforcing Loop
Bond yields, capital flows, and the baht formed a self-reinforcing cycle:
Inflows compressed yields.
Low yields signaled stability, drawing more inflows.
The strong baht reinforced Thailand’s haven reputation.
Competitiveness eroded — paradoxically reinforcing the haven image.
This was not a one-way cause-and-effect chain. Influence ran both ways, creating a loop that kept financial conditions tight regardless of fundamentals.
The bond market became Thailand’s compass — but one pointing toward financial stability at the cost of competitiveness.
Looking Ahead
This sets the stage for the final paradox in Part 4: Thailand’s terms of trade.
Even as markets treat Thailand as a haven, the real economy pays the price.
