CLO ETFs: A High-Yield Income Strategy for the Low-Yield Era

In an era where traditional fixed-income assets struggle to generate meaningful returns, investors are increasingly turning to alternative strategies to meet income needs. Among these, Collateralized Loan Obligation (CLO) ETFs have emerged as a compelling solution, offering a unique blend of yield, credit quality, and structural resilience. For income-focused portfolios, BlackRock's CLO ETFs—particularly the iShares AAA CLO Active ETF (CLOA) and the iShares BBB-B CLO Active ETF (BCLO)—leverage the firm's deep expertise in structured credit to deliver consistent performance even in volatile, low-yield markets.

The Case for CLO ETFs in a Low-Yield World

CLO ETFs are built on the foundation of CLOs, which are structured credit instruments backed by pools of senior-secured corporate loans. These loans are typically rated below investment grade but are secured by the borrower's assets, offering higher recovery rates in distress compared to unsecured debt. CLOs are divided into tranches, with the senior AAA-rated tranches prioritized for repayment. This hierarchical structure ensures that even if some underlying loans default, the senior tranches remain protected, a feature that translates into stable cash flows for ETF holders.

BlackRock's CLOA, which focuses exclusively on AAA-rated tranches, has demonstrated this resilience. As of August 2025, the fund's trailing twelve-month yield stands at 5.93%, a figure that outpaces most high-yield bonds and corporate debt. This performance is underpinned by floating-rate coupons—typically tied to the Secured Overnight Financing Rate (SOFR)—which adjust with interest rate changes. In a rising rate environment, this structure insulates CLOs from the price volatility that plagues fixed-rate bonds.

BlackRock's Structured Credit Expertise

The success of CLO ETFs hinges on the quality of the underlying collateral and the manager's ability to navigate credit cycles. BlackRock's structured credit team, led by Saffet Ozbalci, Peter Hirsh, and Nidhi Patel, brings decades of experience in securitized assets and portfolio structuring. Their approach emphasizes diversification, with CLOA's portfolio comprising over 200 leveraged loans across industries and geographies. This broad dispersion reduces concentration risk, a critical advantage in low-yield environments where investors must stretch for yield without overexposing themselves to sector-specific downturns.

Moreover, CLOs are subject to rigorous structural protections, including overcollateralization tests and interest coverage requirements. These mechanisms ensure that the collateral pool generates sufficient cash flows to service senior tranches even in weak economic conditions. For example, CLOA's modified duration of 2.93 years (as of December 2024) limits its sensitivity to interest rate hikes, a stark contrast to long-dated corporate bonds.

Distribution Consistency and Risk Management

Consistency in income generation is a hallmark of CLO ETFs. CLOA's recent distribution history illustrates this: despite a slight decline from $0.246 in March 2025 to $0.2350 in August 2025, the fund's 12-month dividend growth rate remains stable. This moderation reflects proactive risk management in a volatile macroeconomic climate, particularly as geopolitical tensions and tariff-driven uncertainties create headwinds for leveraged loans in sectors like energy and technology.

By contrast, high-yield bonds often exhibit greater distribution volatility due to their reliance on unsecured debt and higher default risk. CLO ETFs, with their senior-secured collateral and active management, offer a more predictable income stream. For instance, during April 2025's market stress test, AAA CLO tranches outperformed BBB tranches and other credit sectors, underscoring the importance of credit quality in distribution consistency.

Strategic Allocation for Income Portfolios

For investors seeking to build a resilient income portfolio, CLO ETFs like CLOA and BCLO provide a strategic complement to traditional fixed-income assets. Their floating-rate nature and short-to-medium duration make them particularly effective in offsetting the risks of a rising rate environment. Additionally, their low correlation to equities and other credit products enhances diversification.

However, investors should remain mindful of sector-specific risks and liquidity dynamics. While CLOs trade in over-the-counter markets, their depth and institutional investor base (including banks and insurance companies) provide a buffer against short-term dislocations. A well-constructed portfolio might allocate 5–10% to CLO ETFs, balancing their yield potential with the stability of U.S. Treasuries or investment-grade corporate bonds.

Conclusion: A High-Yield Strategy for the Modern Investor

As central banks continue to normalize rates and traditional yield sources shrink, CLO ETFs offer a compelling alternative. BlackRock's structured credit expertise, combined with the inherent advantages of CLOs—floating rates, diversified collateral, and senior-secured protections—positions these ETFs as a cornerstone of income-focused portfolios. While risks such as credit cycles and liquidity constraints persist, the active management and structural safeguards embedded in CLO ETFs make them a robust solution for investors navigating today's low-yield landscape.

For those willing to embrace structured credit, the message is clear: CLO ETFs are not just a niche play but a strategic tool to generate consistent, resilient income in an era of scarcity.
