Global fixed income and equity ETF strategies posted gains and saw inflows surge in August, even amid ongoing macroeconomic turbulence and elevated long-term borrowing costs. International equities maintained their year-to-date lead over U.S. stocks throughout the month, led by notable strength in emerging markets.
Last month was a record-breaking August, as U.S. ETFs saw $180 billion in flows, slightly exceeding the year’s $175 billion monthly average, according to a recent report from State Street Investment Management. Historically, August has been one of the quietest months for flows, averaging just $48 billion — roughly 20% below the standard monthly flows, according to the report. Last month’s strong showing brought year-to-date inflows past $1.4 trillion, positioning the industry for another record-breaking year.
Key Takeaways
- U.S. ETFs garnered $180 billion in August, defying the typical late-summer slowdown. This drove year-to-date inflows past $1.4 trillion, according to a recent report from State Street Investment Management.
- Bond ETFs gathered over $50 billion for the fourth consecutive month. Short-term government strategies captured 94% of all government bond flows.
- Equity ETFs pulled in over $100 billion for a fifth straight month. Meanwhile, sector-specific products saw $8 billion in net monthly outflows.
Broad Equity Momentum & Sector Outflows
The surge in August inflows was driven by both growing ETF adoption and strong underlying market returns, according to the report.
Equity ETFs took in over $100 billion for the fifth month in a row, with every major geographic category seeing inflows. Emerging market funds led non-U.S. equity demand with $6 billion in August flows, lifting the segment’s year-to-date total to a record $50 billion, according to the report. Conversely, sector ETFs saw $8 billion in net outflows, largely driven by a combined $11 billion in outflows from technology and financials strategies.
Fixed Income ETF Inflows Accelerate
Fixed income vehicles remained a major focus of portfolio construction in the current environment. Bond ETFs gathered over $50 billion for the fourth consecutive month, bringing 2026 totals to $407 billion. This brings the category remarkably close to 2025’s annual record of $448 billion, putting fixed income on pace to cross that threshold in September, according to the report.
August’s $55 billion haul represented 2% of total bond ETF assets at the start of the month, while year-to-date inflows account for 18% of starting assets, the report showed. Both relative growth metrics outpaced equity ETFs, underscoring the expanding role of fixed income instruments in strategic asset allocation.
Advisor positioning across fixed income reflected three distinct portfolio themes:
Managing Duration Risks
Short-term government bond ETFs took in $14 billion in August, accounting for 94% of all government bond inflows. On a year-to-date basis, short-term government bond inflows have reached $82 billion — representing 82% of all government flows and eclipsing the previous annual record of $72 billion set in 2022, according to the report.
Capturing Credit Yield via Fixed Income ETF Inflows
Investors actively targeted credit spreads, allocating $4.2 billion to investment-grade corporate bond ETFs and $4.6 billion to securitized exposures ($1.9 billion to mortgage-backed and $2.8 billion to asset-backed markets), according to the report.
Below-investment-grade allocations also saw inflows, with bank loan ETFs adding $470 million as advisors prepared for the Fed to either hold or hike rates.
Building Inflation Resilience via TIPS ETFs
Inflation-linked bond ETFs gathered $1.9 billion in August. This marks the 19th month of positive flows out of the last 20 for the asset class, garnering $24 billion across that period amid ongoing fiscal deficit and supply chain concerns, according to the report.

Hard Assets & Commodities Gain Traction
Macroeconomic uncertainty and currency debasement discussions also lifted hard assets. Broad commodity ETFs added to their momentum, pushing 2026 inflows above $6 billion. This recent strength positions broad commodities to surpass the annual inflow record of $8 billion set in 2021, according to the report.
