Thai 10-year yield rose on global selloff and outflows

  • Global bond selloff A global bond selloff, sparked by a weak US buyback, pushed the Thai 10-year yield up 60 basis points to 2.29%, as foreign investors sold $635 million of Thai bonds, the most in six months.

    This external event was the main driver of the yield increase, directly affecting bond prices.

  • US yields and oil prices Later, US yields near 5.3% and higher oil prices lifted the Thai 10-year yield to about 2.39%, adding to upward pressure on local borrowing costs.

    This shows a second wave of external pressure that kept the yield elevated.

  • BoT rate hold and strong demand The Bank of Thailand held its policy rate at 1% amid weak growth and low inflation, while strong demand for long-dated bonds flattened the curve, helping to limit yield rises.

    This domestic factor counterbalanced the external selloff, supporting bond prices.

  • ThaiBMA outlook ThaiBMA expects the yield to stay range-bound near 2.33%–2.43%, viewing outflows as short-lived given Thailand's strong finances and reserves, which may reassure investors.

    This forward-looking view suggests stability and could influence market sentiment positively.

Thai 10-year yield stays low on weak economy, then rises with US yields

  • Weak economy and low inflation keep Thai rates low Thailand's economy is growing slowly and unevenly, inflation came in far below expectations, and small businesses are still struggling. That keeps the Bank of Thailand's policy rate at 1% and makes long-term bonds attractive, pushing the 10-year yield down and keeping it low.

    This is the main force holding Thai 10-year yields down despite global pressure.

  • Investors buy long-dated Thai bonds as curve flattens Fund managers, insurers and foreign investors bought Thai bonds, especially long-dated ones, as low inflation and a slowing economy made them look cheap. This demand pushes bond prices up and the 10-year yield down, flattening the gap between short and long-term rates.

    Shows the demand side that directly pulls the 10-year yield lower.

  • US yields and oil prices push Thai yields up US 10-year yields rose to around 5.3% on expected Fed rate hikes and higher oil prices, widening the gap with Thailand. That pulled the Thai 10-year yield up to about 2.39% and caused some foreign money to leave Thai bonds, pushing prices down and yields up.

    This is the main upward force on Thai 10-year yields, linking global markets to Thailand.

  • Thai yields seen range-bound as outflows stay short-term ThaiBMA expects the 10-year yield to stay in a 2.33%–2.43% range, close to the third quarter, after rising less than US yields this year. It says any foreign outflows should be short-lived because Thailand's finances and reserves are strong, and long-term bonds still drew buying.

    Gives the balanced outlook: upward pressure exists but is capped by Thailand's strengths.

Global bond selloff and foreign outflows push Thai 10-year yields higher

  • Bank of Thailand holds rate at 1% The Bank of Thailand kept its policy rate at 1% to support the economy, with low inflation and weak SME lending. This keeps short-term yields low and signals no imminent rate hike, which supports bond prices and limits how high the 10-year yield can go.

    This is the starting point for the period and sets the low-rate backdrop that anchors Thai yields.

  • BOT Governor says rates can move either way The BOT Governor said the next move could be a hike or a cut, depending on data, and that low rates for too long carry risks. This keeps investors guessing but suggests no immediate tightening, which is mildly supportive for bond prices and keeps yields from spiking on policy fears.

    It clarifies the policy stance and reduces the chance of a near-term rate hike, which matters for long-term yields.

  • Global bond yields surge after weak US buyback A smaller-than-expected US bond buyback sent global yields soaring. Thailand's 10-year yield jumped 60 basis points to 2.29%, tracking the global move. This directly pushes TH-10Y.GB yields higher, as global yields set the reference for Thai long-term borrowing costs.

    It is the main event that drove Thai 10-year yields sharply higher in this period.

  • Foreign investors dump Thai bonds, outflows hit $635 million Foreign investors sold $635 million of Thai bonds in September, the most in six months, as US yields surged and rate-hike expectations grew. This selling pressure pushes Thai bond prices down and yields up, including the 10-year, as demand weakens.

    It shows a concrete demand shock that directly lifts TH-10Y.GB yields.
