European ETF investors to embrace buffer ETFs and shun liquid alternatives, BBH finds

European institutional investors are pivoting toward buffer ETFs while maintaining skepticism about liquid alternatives, according to findings from Brown Brothers Harriman's 2025 Global ETF Investor Survey. The survey of 115 professional European investors reveals a pronounced preference mismatch: 30% intend to allocate capital to buffer ETFs this year, a threefold margin over the 10% planning exposure to liquid alternatives. This preference split underscores a strategic divergence in how European asset allocators approach downside protection and volatility management.

Buffer ETFs, which employ options strategies to create loss buffers during market downturns, remain an underpenetrated category in Europe despite significant inflows in US markets. The structures appeal to investors seeking defined-outcome solutions with embedded portfolio insurance. Currently, seven buffer strategies are available in Europe, with the Global X S&P 500 Quarterly Buffer UCITS ETF (SPQB) commanding the largest asset base at $88.9 million—illustrating the category's nascent scale relative to broader ETF markets. The contrast with liquid alternatives is notable: these strategies offer similar downside protection mechanisms through systematic approaches such as managed futures, yet investor interest remains muted despite the market's recent reemergence of new product launches, including the first European managed futures ETF since 2020.

The survey data reveals a broader structural realignment in European ETF adoption. Active ETFs command overwhelming investor focus, with 93% of respondents planning to increase exposure. Concurrently, mutual funds face material headwinds, with nearly 50% of investors reducing allocations to the traditional wrapper format. This rebalancing reflects accelerating ETF market maturation and the competitive displacement of older fund structures. The institutional investor base broadly endorses the ETF ecosystem, with 95% planning to increase overall ETF exposure over the next 12 months—a signal of sustained capital rotation into exchange-traded structures and away from traditional vehicles.

The findings suggest European investors prioritize simplicity and transparency in derivative-based strategies over the complexity associated with alternative return sources. Buffer ETFs' mechanical approach to downside hedging—with predetermined loss thresholds and defined participation limits—may resonate more strongly than the discretionary, trend-following mechanics of managed futures and other liquid alternatives. As the European ETF market matures and volatility persists, the disparity between buffer ETF adoption intentions and liquid alternative indifference may narrow, particularly if market dislocations underscore the value of systematic hedge strategies.
