Collateralized mortgage obligation (CLO) issuances in the US elevated by an element of 13 between 2009 and 2019, with the quantity of excellent CLOs greater than doubling to method $647 billion by the top of that interval. Whereas researchers and coverage makers have been investigating the affect of this development on the price and riskiness of company loans and the potential implications for monetary stability, much less consideration has been paid to the drivers of this phenomenon. On this put up, which relies on our recent paper, we make clear the position that insurance coverage corporations have performed within the development of company loans’ securitization and establish the important thing components behind that position.

CLO Investments by Insurance coverage Corporations
Insurance coverage corporations are recognized for investing in company bonds and syndicated company loans. Much less understood is their rising desire for CLOs. Between 2009 and 2019, insurance coverage corporations’ investments in company bonds went from $1.143 trillion to $1.784 trillion, amounting to a 56 % enhance, whereas their investments in company loans went from $18 billion to $42 billion, or a 132 % enhance. Throughout the identical interval, their CLO investments went from $13 billion to $125 billion — an 863 % enhance (illustrated within the chart beneath).

As well as, insurance coverage corporations’ CLO investments confirmed a transparent desire for the riskier mezzanine tranches (rated Aa, A or Baa) over the most secure, triple-A rated tranches. In 2011, 56 % of insurance coverage corporations’ CLO investments had been in triple-A rated tranches whereas 40 % had been in mezzanine tranches. By 2019, the previous had declined to 44 % whereas the latter had risen to 52 % (see the left panel of the chart beneath). Over the identical interval, the scores composition of insurance coverage corporations’ bond investments remained largely unchanged, with 80 % invested in bonds rated single A or Baa (see the fitting panel of the chart beneath).

Attain for Yield by Insurance coverage Corporations
Insurers’ proclivity for CLOs vis-à-vis different securities, and for CLO mezzanine tranches inside that asset class, displays a search-for-yield habits fostered by two options of insurance coverage corporations’ capital regulation: first, a rough definition of threat for capital expenses on property with completely different credit score qualities; second, and in distinction to banking regulation, an analogous remedy of various asset courses, comparable to CLOs and company bonds. Particularly, insurers assign a Nationwide Affiliation of Insurance coverage Commissioners (NAIC) designation (and the related risk-based capital cost) to every funding in line with a mapping from credit score scores. For instance, securities rated Aaa, Aa, or A obtain the NAIC 1 designation and are topic to a (post-tax) risk-based capital cost of 0.3 %. Decrease credit score scores are related to increased NAIC designations and risk-based capital weights. Whereas the NAIC 1 designation is mapped to 3 completely different credit score scores (Aaa, Aa, A), every of the opposite NAIC classes is related to a singular ranking. This construction offers insurance coverage corporations an incentive to put money into property with increased yields inside a NAIC classification.
The rating-based mapping was partially altered in 2010, when the NAIC enacted a regulatory change that basically allowed insurance coverage corporations to report CLO tranches that had been bought at a reduction, or extremely impaired, in a decrease NAIC class than that implied by the rating-based mapping. The brand new capital regime for CLO investments seemingly elevated insurance coverage corporations’ incentives to put money into higher-yielding CLO tranches.
The next chart presents some proof in line with reach-for-yield habits, notably because the regulatory reforms of 2010. The left panel exhibits the time sequence of insurers’ new CLO holdings falling into the NAIC 1 designation as a share of the overall quantity excellent of those tranches primarily based on percentiles of the distribution of CLOs yields for annually. As anticipated, there’s a clear desire for the riskiest tranches inside NAIC 1 (these with yields above the 66th percentile) all through the pattern interval, excluding the monetary disaster, when all yields are squeezed at their minimal ranges. Apparently, the market shares of CLO tranches with yields above the thirty third percentile expertise a pointy enhance within the two years following the 2010 regulatory reform, then register a major drop in 2019, when the reform was repealed. We don’t discover comparable proof in insurance coverage corporations’ company bond investments (proper panel).

Choice for CLOs by Insurance coverage Corporations
Insurers’ search-for-yield habits translated right into a desire for CLOs over company bond investments. Within the pre-crisis interval, when CLO yields had been roughly the identical as or decrease than company bond yields, insurance coverage corporations bought a decrease portion of CLO tranches in comparison with company bonds with the identical ranking. However when the yields on CLOs grew to become considerably increased than these on company bonds in the course of the monetary disaster and, extra markedly, in the course of the post-crisis decade, insurance coverage corporations exhibited a definite desire for CLOs over company bonds with the identical ranking.
Insurers’ desire for CLOs had vital implications for the CLO market. Whereas their market share of company bonds decreased considerably from 2003 to 2019, their share of CLOs nearly quintupled over the identical interval (see chart beneath). Importantly, that enhance was largely pushed by mezzanine tranches rated funding grade (Aa, A or Baa rated), whose market share elevated by an element of eight (from 5 % in 2009 to 44 % in 2019). Additionally, CLO offers wherein insurance coverage corporations maintain bigger investments have bigger mezzanine tranches with funding grade scores, and this has been very true because the regulatory reforms of 2010.

Mezzanine tranches play a crucial position within the origination of CLOs as a result of their junior place permits for the creation of the extremely sought triple-A tranches. Subsequently, insurance coverage corporations’ rising desire for these tranches, notably after 2010, along with their dominant position available in the market for these tranches, is prone to have performed a key position within the post-2010 development of company mortgage securitization.
