Nest builds private credit in nine-figure tickets, weighted to infrastructure

Nest began buying private credit in 2018, which in UK defined contribution terms makes the £68.4bn master trust an early mover twice over—early into the asset class, and early into the argument that illiquidity is compensation rather than a flaw, which James Turner, who runs credit at the scheme, gave to Alternative Credit Investor in its plainest form: "A lot of what we do in private markets is just not accessible in public markets," he said. "We invest [in private markets] as we think the illiquidity is rewarded, and something we couldn't do in public markets."

Nest is unusually willing to publish both where it is and where it wants to go: roughly 18 per cent of net asset value in private assets today, 30 per cent wanted, private credit just under four per cent with an ambition to reach about six—a target Turner describes as not "set in stone." Apply those percentages to the £68.4bn master trust and the picture is an £8bn build from roughly £12.3bn of private assets today to £20.5bn, while the private credit sleeve runs from a little under £2.7bn to about £4.1bn; the arithmetic is ours, the direction is Nest's.

What those small weights say is the part the Mansion House Accord does not tell. Nest is the scheme that got there first, and eight years into the asset class private credit still sits under a twentieth of its book; a UK DC master trust holding 18 per cent of NAV in private assets and aiming for 30 is telling the market that the DC push is a build measured in mandates and years, not a reallocation that has already happened.

Composition matters as much as size. Nest runs three private credit segments—corporate direct lending, infrastructure debt and real estate debt—and weights the second two more heavily, on Turner's logic that the projects behind infrastructure and real estate debt "don't exist in public markets" while the companies in private credit and private equity are "smaller and below the public market region." What the scheme is buying, in other words, is duration and project risk with an illiquidity premium attached, which is a different purchase from buying spread.

Two mandates this year show the pace: in April, Nest awarded Crescent Capital an initial £450m mandate focused on US middle-market companies, and in June it committed £200m to climate-focused infrastructure debt in a partnership with IFM Investors, the Australian pension-backed investor that opened a Singapore office in September to push into Asian private credit. That is £650m in five months across a US corporate strategy and an infrastructure one, both written as nine-figure single-manager tickets. The pattern fits what this publication has argued about the direct lending reset—falling volume has accompanied capital concentrating in the largest managers while secondaries funds absorb seasoned books, rather than less capital overall—because a scheme Nest's size cannot assemble a private credit book from dozens of small commitments; it writes a handful of large ones, and the UK DC build will surface in a short list of managers' fundraising totals rather than across the market.

Nest is not alone at the infrastructure end. BNP Paribas Asset Management's alternatives arm closed a €1.2bn junior infrastructure debt fund in September, a reminder of how many institutional balance sheets are chasing the same paper.

US direct lending has spent the past year under heightened scrutiny over credit quality and AI disruption, largely because so much of the market lends to software companies, and the stress has shown up in business development companies through a flurry of retail redemptions over the past two quarters with more expected. Asked directly whether that worries Nest, Turner said the scheme is not currently worried about its portfolio; the published extract ends mid-sentence at that point.

His composure has some aggregate support. Defaults in US private credit have been falling rather than rising: S&P data put the US default rate at 3.9 per cent by mid-2026 even as AI anxiety hung over software-heavy books, as this publication reported in August. The software concentration that unsettles BDC investors sits in corporate direct lending, the lighter-weighted part of a private credit book that is itself under four per cent of NAV—the likeliest explanation for Turner's calm. On the disclosed numbers, that exposure is small.

There is a version of the April mandate that reads as good timing: retail investors have been selling BDCs for two quarters while Nest has been awarding US middle-market mandates, and a 30-year horizon is worth something when the marginal seller needs a bid this quarter. The counter-argument, made in these pages about recoveries, is that default counts flatter loans that have not yet been worked out, and realized recoveries rather than default rates are where loss assumptions get tested as early unitranches season. Nest's new money is going into a middle market that is still carrying earlier vintages.

Just under four per cent of NAV today, roughly six as an ambition, and no date attached—Turner's caveat that the number is not "set in stone" leaves the scheme free to slow down if credit turns. At the pace of this year's two mandates, the £1.4bn needed to reach six per cent at current NAV is about a year's work, and the Crescent mandate was written as an "initial" £450m, a structure that lets Nest pause without appearing to reverse course.
