U.S. short-term yields now offer an unusually large advantage over much of Asia.
Bank of America estimates that the GDP-weighted two-year yield across emerging Asia is 174 basis points, or 1.74 percentage points, below the two-year U.S. Treasury yield, according to a note shared with TheStreet. A broader bond-market measure also puts Asia’s yield discount to Treasuries at its widest in more than 20 years.
That kind of gap would normally favor the dollar. But BofA said lower-yielding currencies, including the South Korean won, Chinese yuan, and Singapore dollar, have held up better in 2026 than higher-yielding currencies such as the Indian rupee, Indonesian rupiah, and Philippine peso.
The bank sees another set of flows pulling the region apart: North Asian exporters are bringing in dollars from booming technology shipments. At the same time, oil importers need more dollars to pay energy bills as Brent trades above $100 a barrel.
Brent remained above $100 on Wednesday, Oct. 7, as investors weighed threats to global supply.

Why a 20-year yield gap isn’t sinking all Asian currencies
Higher U.S. interest rates still give investors an incentive to hold dollar assets.
But BofA says bond yields are no longer the only force driving currencies. Cross-border equity flows, investors’ currency hedges, and exporters converting dollar revenue back into local currencies are playing a bigger role.
BofA also says some of the extra yield offered by developed-market bonds reflects higher fiscal and inflation risk.
The export effect is particularly visible in South Korea and Taiwan, where technology shipments have surged.
Chip exports are giving Korea and Taiwan an FX cushion
South Korea exported a record $120.9 billion of goods in September, up 83.5% from a year earlier, Reuters confirmed.
Semiconductor shipments rose 262.8% to $60.3 billion as AI infrastructure spending fueled memory demand and chip prices.
Those exports generate dollar revenue. When Korean companies convert part of those earnings into won, they sell dollars and buy the local currency, helping support the won.
More Bank of America:
Taiwan has a similar source of support.
BofA said Taiwan’s current-account surplus reached about 24% of GDP in the second quarter, and the bank expects higher prices for technology exports to keep supporting export revenue.
