Southeast Asian Bonds Face El Niño Inflation Pressure
El Niño is a weather pattern that can cause droughts in Southeast Asia.
Droughts can make food more expensive.
When prices rise, central banks may raise interest rates to control inflation.
Higher interest rates can make government bonds less attractive and push their yields higher.
Analysts say this could hurt Southeast Asian bonds.
The Philippines and Thailand may face greater risks because food prices have a large effect on their inflation measures.
Regional bonds are also being pressured by higher United States Treasury yields and rising oil prices.
Officials in the Philippines and Thailand have already said El Niño could affect inflation.
Investors may be underestimating how long these price increases could last.
A resurgent El Niño could deepen Southeast Asia’s bond selloff, analysts say.
Drought-related food inflation may push regional bond yields and interest rates higher.
The Philippines and Thailand are especially exposed because food has a large CPI weighting.
Philippine 10-year yields rose 71 basis points last quarter to 7.62%.
Higher United States Treasury yields and oil prices are already pressuring regional debt.
