Global ETF assets climbed to $21.24 trillion by February 2026, up 7% year-to-date, as investors continue pouring capital into both traditional and alternative strategies, according to a report from LSEG Data & Analytics.
Among the fastest-growing corners of this market are alternative ETFs, which attracted nearly $130bn in net inflows during 2025 alone, cementing their position as the third largest ETF category globally with $602.1bn in assets under management, it said. The shift reflects a broader change in investor priorities, as wealth managers and institutions hunt for new sources of income amid persistent inflation, volatile interest rates and tighter financial conditions.
Floating-rate income has emerged as a particular focus. CLO ETFs, funds offering exposure to collateralised loan obligations, have become one of the standout growth stories in the ETF market. In the first six weeks of 2026, net inflows into CLO ETFs totalled $4bn, pushing global AUM above $35bn and more than doubling compared to the same period a year earlier, it said. While AAA-rated strategies continue to attract the lion’s share of capital, investor appetite is broadening, with growing interest in BBB/BB mezzanine CLO ETFs as familiarity with the asset class deepens.
Several factors are driving this momentum, LSEG said. CLO tranches, particularly those rated AAA, pay floating-rate coupons that reset regularly, helping investors manage duration risk while keeping income aligned with prevailing rates. In an environment where rates are expected to remain elevated for longer, this characteristic offers a compelling alternative to traditional fixed-rate corporate bonds.
AAA CLOs also typically offer higher spreads than comparably rated corporate or sovereign debt, giving investors enhanced yield without a proportional increase in credit risk.
Structural resilience adds further appeal. CLOs are constructed with substantial credit enhancement and subordination beneath AAA tranches, and historically those tranches have suffered zero principal losses across multiple credit cycles, it noted. For conservative investors, this track record is a significant draw. Beyond yield, CLO ETFs also offer portfolio diversification benefits, as the underlying pools span hundreds of loans across a range of sectors, broadening exposure beyond conventional fixed income.
Accessibility has also improved markedly. CLO investments traditionally required minimum tickets of $250,000 to $1m and involved bilateral trading. ETF structures reduce the barrier to entry to a single share and provide daily liquidity. The growing range of products, from AAA-focused strategies to mezzanine-oriented vehicles, is further expanding the options available to investors seeking to express differentiated views across the credit cycle.
