Emerging market debt draws $11.3B despite surging U.S. yields

Foreign investors added a net $11.3 billion to emerging market portfolios in August, marking the second consecutive month of inflows even as the 30-year U.S. Treasury yield climbed to its highest level in nearly two decades, according to data released Friday by the Institute of International Finance.investing+1

The resilience of emerging market debt demand in the face of rising long-term U.S. yields suggests a structural shift in how investors are approaching the asset class.

Debt Drives the Flows

Debt investments accounted for nearly all of the August inflows, attracting a net $11.2 billion even without new sovereign issuance during the month. Equity inflows were nearly flat at roughly $0.1 billion. The net inflow slowed from a revised $24.9 billion in July and compared with a $35.9 billion inflow in August 2025.gate+2

Year-to-date emerging market debt inflows reached roughly $243 billion, compared with $212 billion over the same period last year. Equity flows told a starkly different story, with $87.5 billion leaving the asset class so far this year compared with a $7.4 billion outflow over the same period in 2025.investing+1

Emerging market sovereign issuance reached a record $191.5 billion through August, about $30 billion above the same point last year, with Saudi Arabia and Pakistan already returning to the primary market in September.investing

Flows Defy Rising U.S. Yields

The inflows came as the 30-year U.S. Treasury yield hit a 19-year high during August, surging past 5.3%. Such an environment has historically triggered outflows from emerging markets.cnbc+1

"Flows that continue through that backdrop suggest a demand base allocating to EM on its own merits rather than on a benign global rate environment," IIF senior economist Jonathan Fortun wrote.investing

Foreign investors also pulled roughly $3.5 billion from Chinese equities during the month, even as broader emerging market flows stayed positive.cryptobriefing

Fed Hike Looms Over Outlook

Long-term yields have remained elevated in September. Hotter-than-expected U.S. inflation data released Friday — with core CPI rising 0.3% in August, above the 0.2% economists expected — pushed the probability of a Federal Reserve rate hike at the September 15-16 meeting to roughly 85%, according to Reuters Thomson Reuters Corporation ↘ 4.69%, up from about 70% before the report. Whether emerging market debt can sustain its appeal through a tightening cycle remains the central question heading into the final months of the year.reuters
