While fixed-income ETFs are seeing strong inflows this year, academics from a trio of U.S. business schools suggest fixed-income ETFs can suck the liquidity out of corporate bonds during times of market stress. According to them, the potential problem stems from the creation and redemption baskets that ETF issuers trade with market makers, known as authorized participants (APs), to handle inflows or outflows from their ETFs. Unlike equity ETFs, bond funds’ creation and redemption baskets typically do not include every bond in the index they are tracking as this could include hundreds or even thousands of separate issues. In their paper, Steering a Ship in Illiquid Waters: Active Management of Passive Funds, the academics argue that in normal times a bond’s inclusion in an ETF basket makes the bond more liquid. This is due to a random mix of creations and redemptions increasing trading activity. But, during a crisis, when many investors are running for the exits, redemptions hugely outweigh creations. When that happens, if a bond is included in the basket, the APs “may then become reluctant to purchase more of the same bonds, reducing their liquidity,” according to the paper. However, other bond strategists disagree, including Dan Izzo, chief executive of GHCO, an ETF market maker. Izzo, who argues that the rise of ETFs had actually increased liquidity during periods of market stress, stated that “The causality ran in the opposite direction — it is because some bonds are illiquid that they increasingly feature in redemption baskets as sell-offs intensify, not vice versa.”

As investors increasingly buy ESG funds, there has also been an increase in academic research on the impact of implementing ESG constraints on equity portfolios. However, there hasn't been as much attention paid to research on ESG fixed-income investing. Inna Zorina and Lux Corlett-Roy published their study “The Hunt for Alpha in ESG Fixed Income: Fund Evidence from Around the World,” in the Fall 2022 issue of The Journal of Impact and ESG Investing. In the study, they examined whether ESG fixed-income funds generate out- or under-performance after controlling for systematic fixed-income factors. They found that while ESG fixed-income funds with a higher level of risk generally produced higher returns, most ESG fixed-income funds did not produce statistically significant positive or negative gross alphas. In fact, only 7% of funds managed to deliver greater returns at a lower level of risk relative to the respective benchmark. The study revealed that across ESG fixed-income funds with a European, U.S., and global focus, performance was mainly driven by systematic fixed-income factor exposures such as term and default risk. The results led Zorina and Corlett-Roy to conclude: “ESG fixed-income mutual funds and ETFs have not consistently delivered statistically significant gross alpha controlling for key fixed-income factors. The majority of alphas are statistically insignificant and therefore indistinguishable from zero. This conclusion is similar across fixed-income funds with a European, US, and Global ESG investment focus.”

Investors are piling into the investment-grade market at a record rate due to higher yields and concerns over riskier debt. A total of $19 billion has been poured into funds that buy investment-grade corporate debt since the start of 2023. That marks the most ever at this point in the year, according to data from fund flow tracker EPFR. The money pouring into the asset class underscores an eagerness among investors to buy historically high yields provided by safer corporate debt after years of investing in riskier debt in search of returns. According to Matt Mish, head of credit strategy at UBS, “People basically think that fixed income, in general, looks a lot more attractive than it has in prior years. The euphoria around investment grade is basically more broadly this euphoria around yields. At least relative to last year and really relative to most of the last decade, [high-grade corporate debt] is offering yields that are considerably higher.” For instance, average US investment grade yields have jumped to 5.45% from 3.1% a year ago. The soaring yields come as a result of the broad sell-off in fixed income over the past year as the Federal Reserve rapidly lifted interest rates to help tame sky-high inflation.
