Insurance-linked securities and reinsurance sidecar investments made by Eaton Vance through three of its mutual funds have risen significantly in the last half-year, increasing by more than 126% to reach almost $680 million by April 30th, with brand new allocations made to structures linked to Arch Capital, PartnerRe and QBE, as well as to one unknown entity.
Eaton Vance, part of Morgan Stanley Investment Management, has been allocating to certain insurance-linked securities (ILS) funds, segregated accounts and reinsurance sidecars from three of its mutual fund portfolio strategies for a while now.
When we last reported on these ILS and reinsurance sidecar allocations, the Eaton Vance mutual funds had seen positive value accrued under these investments, while the holding value of the ILS positions had reached just over $300 million at October 31st 2025.
Notably, in the next six months of record, to April 30th 2026, Eaton Vance’s mutual funds have made entirely new allocations within the ILS portfolio, with three new reinsurance sidecars invested in, as well as one new segregated account private ILS opportunity.
Here, Eaton Vance is partnering with major players in the reinsurance market, making new allocations to reinsurance sidecars from PartnerRe, QBE and also allocating to a private ILS segregated account structure managed by Arch Capital. On top of this, there’s another sidecar arrangement that we have not yet identified, all of which shows on expansive appetite for accessing more returns from the reinsurance and ILS market.
The new allocations include QBE’s first casualty reinsurance sidecar George Town Re, while the PartnerRe sidecar structure is not named, so it could be a cell under its Lorenz Re vehicle.
For the Arch Capital allocation, this has been made to segregated accounts of the Voussoir Re Ltd. vehicle, a structure we have covered a number of times before.
The as yet unknown structure is a sidecar named Beacon RE, which the Eaton Vance funds have also made their first investment allocations to in the last half-year running to April 30th 2026, it appears.
These ILS and reinsurance investment allocations are made for the Eaton Vance Global Opportunities, Global Macro and Global Macro Absolute Return Advantage fund strategies.
Eaton Vance is a good example of a large multi-asset class investment manager that is now increasingly integrating reinsurance-linked returns within some of its strategies and funds. It’s worth noting that there may be other strategies managed by Eaton Vance that also allocate to reinsurance sidecars or ILS strategies, but these are the three we see regular filings made for.
One of the more notable additions in the last six months of record, is the fact one of these funds has allocated to QBE’s recent George Street Re casualty reinsurance sidecar structure.
The Global Opportunities Portfolio mutual fund has a roughly $63.2 million allocation to the George Street Re casualty sidecar, which we believe is the first non-cat investment made by these funds.
Also new in the last half-year is a sidecar allocation partnership investment made with reinsurer PartnerRe. As we said the name of the structure has not been disclosed, but it could be an investment into a Lorenzo Re cell, one of PartnerRe’s main third-party capital vehicles.
All three of the Eaton Vance funds have allocated to the PartnerRe sidecar, with the total holdings in the structure amounting to nearly $115 million.
Another new access point established is to a reinsurance sidecar named Beacon RE. At this time we do not know who the sponsor is, so this could be a private arrangement of sorts.
Again, all three Eaton Vance mutual funds have invested into Beacon Re, totalling almost $92.3 million allocated.
The final new access point to reinsurance-linked returns established in the last half-year, is an investment into Arch Capital’s structure named Voussoir Re Ltd.
The Voussoir Re vehicle became a key third-party capital structure for Arch since the structure’s launch in 2019, most recently we covered a share issuance from the vehicle in April this year.
Across two of the Eaton Vance mutual funds, the investments in Voussoir Re amount to almost $74.6 million, made by the Global Opportunities and Global Macro Portfolio funds.
Of the investment access points that previously existed, the most notable increase is to Mt. Logan Capital Management, the Everest third-party reinsurance capital unit.
The Eaton Vance fund investments (with all three allocating) into Mt. Logan Re have risen from $66.5 million at October 31st 2025, to reach $145.4 million as of April 30th 2026, a meaningful increase.
All three funds also allocate to the Swiss Re managed Core Nat Cat Fund strategy, which enables investors to participate in Swiss Re’s global cat book. This investment has increased in value from $96.7 million to $103.4 million over the six months to April 30th 2026.
The Eaton Vance funds also invest in reinsurer PartnerRe’s strategy named the PartnerRe ILS Fund SAC Ltd., with this increasing from a $68.9 million valuation to reach $74.2 million at April 30th this year.
Given the addition of a PartnerRe reinsurance sidecar investment as well, this now makes the reinsurer the largest source of ILS and reinsurance investment allocations for the three Eaton Vance mutual funds, with almost $189 million invested at April 30th across the two access points.
Finally, these mutual funds have also had allocations to Munich Re’s Eden sidecar range, but these have been shrinking which we believe is due to the global reinsurer deciding to scrap its sidecar program for 2026.
The Eden Re II investments have shrunk in value to only $11.6 million at April 30th 2026, down from $68 million at October 31st 2025.
The increased allocations made to reinsurance and ILS, with the addition of new sidecar and segregated account partnerships, clearly demonstrates a strong appetite for the asset class from Eaton Vance.
With almost $680 million now allocated to reinsurance sidecars and ILS strategies across these three mutual funds, it shows the potential for meaningful amounts of capital to flow into the sector from multi-strat asset managers of this kind.
The total cost of those investments is reported to have been $568 million, showing accrued returns and profits already being made. Those returns should accelerate given a meaningful amount of the total invested in ILS and sidecars had been made more recently.
The addition of some diversification in the form of QBE’s casualty reinsurance sidecar is also notable, as it shows an asset manager that appreciates ILS and reinsurance returns can be derived from a broader swathe of the insurance market than catastrophe risk alone.
It’s worth also noting that the ILS investments remain a small component of the multi-billion dollar portfolios of each of these Eaton Vance mutual funds. ILS and reinsurance sidecar investments make up just 3.6% of the Global Opportunities Portfolio, 1.2% of the Global Macro Portfolio and 2.1% of the Global Macro Absolute Return Advantage Portfolio fund strategies.
At a time when global investors are seeking more diversification and insulation than typical index funds are offering, diversified multi-strategy investment funds such as these are also growing in popularity, which could ultimately drive more asset managers to explore ILS and reinsurance as drivers of differentiated returns to add to their strategies.
