Surging US Treasury Yields Widen Emerging Asia Bond Gaps
US government bonds became less attractive in price because their interest rates, called yields, rose sharply.
This made the difference between US and Asian bond yields larger.
Investors may move money from Asian bonds into US bonds if they prefer the higher US returns.
That could weaken some Asian currencies and make it harder for local central banks to lower interest rates.
Higher interest rates can make borrowing more expensive for people and businesses.
Malaysia and Thailand saw especially wide gaps compared with US bonds.
Asian bond markets have not fallen as sharply as US Treasuries because inflation has remained stable and currencies have been resilient.
Strategists said Indonesia and the Philippines appear more vulnerable, although Asian markets overall have shown resilience.
The 30-year US Treasury yield reached its highest level since 2004, while the 10-year yield hit its highest since 2007.
Malaysia’s 10-year yield discount to US Treasuries widened to 125 basis points, the widest since 2007.
Thailand’s 10-year bond gap reached 290 basis points, nearing a record low, while Indonesia’s spread narrowed to 188 basis points.
Strategists warned that higher US yields could reduce inflows or trigger capital outflows from emerging Asian bond markets.
Asian markets have so far seen more modest yield increases, supported by stable inflation and resilient currencies.
- Who
- US Treasury investors, emerging Asian bond markets, regional central banks, and strategists including Stephen Chiu and Homin Lee.
- What
- A sharp rise in US Treasury yields has widened yield gaps with bonds in several emerging Asian economies, increasing concerns about capital outflows.
- When
- This week; the China-US 10-year yield gap reached a record earlier this month.
- Where
- The United States and emerging Asian markets, including Malaysia, Thailand, Indonesia, South Korea, China, and the Philippines.
- Why
- Higher US yields may attract investment away from Asian bonds, pressure local currencies, and encourage central banks to keep interest rates elevated.
Outflow and Vulnerability Concerns
Asian Market Resilience
Investment flows
Outflow and Vulnerability Concerns
Stephen Chiu said higher US yields could spur foreign outflows or reduce net foreign inflows into emerging Asian bonds.
Asian Market Resilience
Homin Lee said the rise in US yields has also revealed the resilience of Asian dollar and local debt markets, apart from more vulnerable Indonesia and the Philippines.
Market pressure
Outflow and Vulnerability Concerns
Wider yield gaps could pressure local currencies and push regional central banks to maintain high interest rates, increasing borrowing costs and potentially slowing growth.
Asian Market Resilience
Emerging Asian yields have risen more modestly than US Treasury yields, with stable domestic inflation and resilient currencies helping the region avoid a more severe selloff.
Most exposed markets
Outflow and Vulnerability Concerns
Longer-dated bonds in low-yield markets such as South Korea and Thailand are particularly at risk from higher Treasury yields.
Asian Market Resilience
The differing performance across Asia suggests that not all regional markets are facing the same degree of vulnerability; the sources specifically identify Indonesia and the Philippines as more vulnerable.
