Monthly recap: Core equity ETFs pace flows to record territory
We saw no easing of ETF flows across the so-called summer holiday period. In July, flows notched a new monthly high, while August marked the second-highest monthly tally on record. Global equities advanced in August as strong corporate earnings and resilient economic data boosted investor sentiment. Higher rate expectations, geopolitical tensions and commodity volatility did little to derail the rally.
Following the two-month summer surge, 2026 flows stand at $374.1 billion year to date. That’s ahead of the 2025 full-year total of $371.7 billion, with four months to go.
Equity ETFs captured $41.0 billion of net inflows in August. Core equity ETFs accounted for $22.8 billion of net inflows, with investors favouring US, global and developed market exposures. Smart beta and sustainable equity ETFs also enjoyed a relatively strong month.
Fixed income ETFs saw $8.2 billion of net inflows in August. Government bond ETFs had $2.8 billion of net inflows for the month, while ultra-short and corporate exposures also welcomed healthy flows. On a regional basis, investors focused on US, euro area and global bond ETFs.
Commodity, alternative and multi-asset ETFs all enjoyed net inflows in August. Commodity ETFs saw notably high net inflows of $7.5 billion against a backdrop of rising demand for gold.

Funds investing in fixed interest securities carry the risk of default on repayment and erosion of the capital value of your investment and the level of income may fluctuate. Movements in interest rates are likely to affect the capital value of fixed interest securities.

The level of income may fluctuate and movements in interest rates are likely to affect the capital value of bonds.
The Funds may use derivatives in order to reduce risk or cost and/or generate extra income or growth. The use of derivatives could increase or reduce exposure to underlying assets and result in greater fluctuations of the Fund's net asset value.
