ETFs have become an increasingly versatile tool in institutional portfolios, moving beyond tactical market access and liquidity management to serve as strategic building blocks. That evolution is now extending into alternative credit, including collateralized loan obligations (CLOs), which provide exposure to floating-rate corporate loans across different risk and return profiles. Fredrik Nilsson, Head of Nordic Distribution at Invesco, discusses how institutional ETF usage is evolving and why CLOs are emerging as an increasingly relevant application.
From Tactical Tool to Strategic Allocation
Institutional investors have traditionally used ETFs for efficient market access, tactical positioning and portfolio transitions. That role is changing, however, as allocators increasingly incorporate ETFs into longer-term portfolio construction. Nilsson says the shift is visible across the Nordic region, with investors becoming more comfortable using the structure for exposures they intend to hold strategically rather than simply as temporary positions.
“We’ve seen ETFs move over the past couple of years from being primarily tactical instruments to becoming more strategic portfolio-building blocks for institutional clients across the region,” Nilsson says. “It’s a shift from efficient market access and transition management towards longer-term allocations.”
“The investor base [in the Nordics]is very sophisticated and well suited for active ETFs.”

Beyond traditional equity and bond exposures, institutional investors are increasingly considering products that combine the implementation advantages of an ETF with more specialized or actively managed outcomes, including systematic equity, enhanced equity and specialist credit strategies. While the U.S. remains the more developed market for active ETFs, Europe is growing rapidly from a lower base. Nilsson sees the Nordic region as particularly well suited to active and alternative ETF strategies. “The investor base is very sophisticated and well suited for active ETFs.”
Nordic Investors Want a Portfolio Solution, Not Simply a New Product
That sophistication also means Nordic allocators are unlikely to adopt a product simply because it has gained traction elsewhere. Due diligence remains central to the process, with investors examining liquidity, capacity, ESG characteristics and the broader market infrastructure supporting a strategy.
“We do see a difference in how adoption plays out here in the Nordics compared with the U.S.,” says Nilsson. “There is a proper due diligence process. Investors look at liquidity, capacity, ESG characteristics and, of course, the quality of the underlying capital-market ecosystem. It’s a more rigorous process.”
“There is less focus on copying the U.S. product mix and more on selecting strategies that solve specific portfolio problems.”

The result is a market where the portfolio application of a product matters as much as its structure. “It’s clearly not about first-mover advantage in the way you might see in other markets,” Nilsson points out. Instead, allocators are looking for strategies that address identifiable portfolio requirements. “There is less focus on copying the U.S. product mix and more on selecting strategies that solve specific portfolio problems,” he claims. This provides a useful context for the development of CLO ETFs.
Bringing CLO Exposure Into an ETF Wrapper
CLOs are portfolios of predominantly senior secured corporate loans that are pooled together and divided into different layers, or tranches, with different levels of risk and return. The structure distributes cash flows according to a defined waterfall, with senior tranches receiving payments before more junior securities. “There is a securitization of a diversified pool of predominantly senior secured loans,” Nilsson explains. “The liabilities are issued in different tranches with different priorities, and the cash flows then follow a standard waterfall.”
The CLO market has grown into a substantial segment of global credit markets. Nilsson estimates that the combined U.S. and European CLO market is now close to $1.4 trillion, with AAA-rated securities accounting for roughly 60 percent of the universe. That is the segment targeted by Invesco’s AAA CLO Floating Rate Note ETFs.
“CLO ETFs offer a different return driver for investors moving away from fixed-rate government and corporate bonds. In an ETF, CLOs can provide a liquid, tradeable complement to existing, less liquid private credit allocations.”

For institutional investors, the attraction is partly the different source of returns compared with traditional fixed income. “CLO ETFs offer a different return driver for investors moving away from fixed-rate government and corporate bonds,” Nilsson says. “In an ETF, CLOs can provide a liquid, tradeable complement to existing, less liquid private credit allocations.”
The floating-rate nature of the underlying loans and CLO securities is an important consideration. Investors can gain exposure to credit spreads without taking the same level of interest-rate duration associated with traditional fixed-rate bonds. “CLO ETFs allow investors to capture a spread over cash and traditional short-duration investment-grade credit while keeping duration risk relatively low,” Nilsson says. “And, of course, the ETF wrapper provides daily liquidity.”
The ETF Wrapper Can Simplify Implementation
Historically, direct CLO investment required specialist expertise, access to over-the-counter markets, sufficient scale and ongoing security-level credit analysis. “Direct investing traditionally required a lot of overhead: specialist expertise, access to OTC markets, sufficient scale and ongoing credit analysis at the security level,” reiterates Nilsson.
“What the UCITS ETF wrapper brings to the table is a diversified portfolio of CLO notes in a familiar structure, with daily valuation and exchange trading.”

An ETF can consolidate a diversified portfolio of CLO notes into a single listed vehicle, reducing some of that operational complexity. “What the UCITS ETF wrapper brings to the table is a diversified portfolio of CLO notes in a familiar structure, with daily valuation and exchange trading,” he says. The ETF does not change the underlying characteristics of the asset class, but it can change how easily those characteristics can be incorporated into a broader portfolio.
Active Management Matters in CLO ETFs
The case for active management is particularly relevant in CLOs because the underlying collateral is not static. “We see a need for active management because two CLOs can differ materially in terms of collateral and loan quality, among other things,” Nilsson argues. “A specialist manager can assess those differences and potentially add value.” For investors, that makes portfolio construction and manager selection important considerations alongside the headline credit rating.
“The floating-rate nature and CLO structure reduce both interest-rate duration and credit risk, but it doesn’t eliminate spread risk.”

“At the underlying asset level, the main risks are deterioration and defaults in the senior loan collateral,” Nilsson says. “You can have downgrades, spread widening and weaker recoveries. The key is to use our expertise to invest in the highest quality CLO issuers, while also focusing on vintage and liquidity.” While the floating-rate structure reduces interest-rate sensitivity, structure and cash-flow waterfall also reduces credit risk for those highest rated tranches. “The floating-rate nature and CLO structure reduce both interest-rate duration and credit risk, but it doesn’t eliminate spread risk.”
Liquidity Requires a Different Mindset
For Nilsson, one of the more important developments is not simply that ETFs are expanding into CLOs, but that the underlying fixed-income market infrastructure has developed sufficiently to support the structure. ETF shares can trade throughout the day, but individual CLO notes are generally less liquid, and their valuations may not adjust as frequently as those of more actively traded securities. “Investors can trade in the secondary market, where bid-ask spreads can widen,” Nilsson says. “But there is now an element of primary and secondary liquidity that wasn’t available when investors accessed this asset class through more traditional structures.”
“By enabling authorized participants to arbitrage differences between ETF prices and the value of the underlying portfolio, it helps maintain efficient pricing and supports robust secondary-market liquidity.”

The creation and redemption mechanism is one of the key strengths of the ETF wrapper. “By enabling authorized participants to arbitrage differences between ETF prices and the value of the underlying portfolio, it helps maintain efficient pricing and supports robust secondary-market liquidity,” explains Nilsson. “This feature is particularly relevant in CLO markets, where underlying securities are often valued using evaluated prices or dealer quotes that may not fully reflect current executable levels.” Through continuous exchange-based trading and arbitrage, ETF prices can serve as an important price-discovery mechanism, incorporating evolving market information in real time even when underlying valuations adjust more slowly. Although premiums, discounts and wider spreads can emerge during periods of market stress, the ETF ecosystem has consistently demonstrated its ability to facilitate liquidity and provide timely market signals across both liquid and less liquid fixed-income asset classes.
“We always advise investors to reach out to the ETF issuer’s capital markets team and discuss the timing and method of execution,” Nilsson says. Depending on market conditions and the size of the order, execution can involve cash, in-kind creation or a combination of the two. “There can be significant cost savings in the execution phase for an illiquid asset class like this,” he adds. For institutional investors, that implementation discipline may ultimately be as important as the strategic rationale for adding CLO exposure.
