When the world's biggest pools all tilt home at once, who is left to fund the global build-out?

The hook is a single afternoon meeting in Seoul. South Korea's National Pension Service, the world's third-largest pension fund at roughly KRW 1,360trn (~$1.0–1.2trn), is voting today on its 2027–2031 medium-term asset allocation plan; the fund-management committee has already signalled broad support for raising the strategic target for Korean equities after this year's KOSPI rally pushed the actual share above 24.5% — well past the 14.9% 2026 target and the 19.9% prior upper bound (Bloomingbit, May 27, 2026; KED Global, May 18, 2026). On its own it is one allocator ratifying a market move. Read against the rest of this year's policy calendar, it is the fourth simultaneous home-tilt at the level of strategic policy by a mega-allocator inside one year — and that pattern, not the Korean number, is the question for a universal owner.

What the evidence says

The pattern is visible across four jurisdictions, and it is showing up in the policy mix, not just in tactical positioning.

In the United Kingdom, the Pension Schemes Act 2026 received Royal Assent on April 29, 2026, hardwiring a reserve power that lets the government require master trusts and group personal pensions to put up to 10% of default funds into qualifying private-market assets, of which up to 5% can be a UK-specific carve-out, in line with the voluntary 17-provider Mansion House Accord (WTW, April 2026). The reserve power cannot be triggered before January 1, 2028, and falls away in 2032 under the sunset clause brought forward during ping-pong, but it puts a statutory backstop behind a home-tilt for £1tn+ of DC default capital.

In Canada, Prime Minister Mark Carney announced the Canada Strong Fund on April 27, 2026 — a federal vehicle seeded with CAD $25bn over three years and explicitly designed to attract private and institutional capital alongside federal investment into domestic infrastructure, energy, critical minerals and advanced manufacturing (Prime Minister of Canada, April 27, 2026).

In Japan, GPIF has so far reaffirmed the 25/25/25/25 split between domestic equities, foreign equities, domestic bonds and foreign bonds for FY2025 onward, but the policy mix is being publicly debated in the wake of a sharp JGB repricing — the first live discussion of a meaningful rebalance for the world's largest public pension in five years.

In Korea, today's NPS committee vote sits on top of a January meeting that already lifted the 2026 domestic equity target by 0.5 percentage points to 14.9% and the domestic bond target by 1.2 points to 24.9%, while cutting overseas equities by 1.7 points to 37.2% (UPI, May 24, 2026).

Why this matters at the level of system flow comes from the primary research. The European Central Bank's working paper on home bias (ECB, 2024) finds that pension and insurance balance sheets have been the dominant non-bank source of cross-border patient capital in the post-GFC era; even a modest policy-level tilt at this size meaningfully changes the marginal supplier of long-term funding for foreign assets. BIS research on the dollar and EM flows (BIS QR, September 2024) shows the dollar cycle remains the single biggest determinant of capital flows to emerging markets, but that institutional positioning is a slower-moving second factor that compounds with FX. And the Thinking Ahead Institute's Total Portfolio Approach hub (TAI / WTW, 2025) — co-authored with Future Fund, CPP Investments, NZ Super and GIC — argues that mega-allocators are dissolving asset-class silos exactly to give themselves room to over- or under-tilt by mandate, which is precisely the architecture being used to formalise the home moves.

Sentiment data corroborates that something has shifted at the strategic layer but in the opposite direction at the tactical one. The BofA May Global Fund Manager Survey (BofA, May 19–20, 2026, 200 panelists, $517bn AUM, survey period May 8–14) showed global equity allocation jumping to net +50% overweight — the steepest one-month jump since 2001 — with the US slice swinging from a net -10% underweight in April to a net +20% overweight in May. The IIF, by contrast, projects non-resident flows to emerging markets at $935bn in 2026, up from $887bn in 2025, but warns the increase is almost entirely official flows (largely to Argentina and Ukraine) while private flows are flat to down (IIF, 2026). Tactical money is concentrating; strategic money is being domesticated.

Where it is contested

This is not a settled story.

First, the policy targets are not the same instrument. The UK reserve power is conditional and has a two-year lead time. Canada's $25bn is a seed for a vehicle that does not yet have its full mandate. Japan's debate may end with no change. Korea's lift today, if it lands, would be the most concrete and immediate. So calling this a "global home-tilt" is right at the level of direction and wrong at the level of velocity.

Second, the evidence on whether home bias is harmful to the home country is genuinely mixed. The ECB paper argues recent home bias has been less biased than the canonical 1990s findings imply — improvements in disclosure and cross-border investment infrastructure have shrunk the informational case for over-weighting home — and that home tilts can also stabilise the home market in shocks.

Third, the global build-out — AI, grid, climate transition — needs an enormous amount of patient cross-border capital and there is no agreement on who supplies it if pensions retrench. Sovereign wealth funds and large insurers might, but Indonesia's INA, $4.2bn deployed with ~30% in digital infrastructure, is a useful counter-example: their home-tilt is into AI, not away from it.

From the allocator's seat

The portfolio question for a true universal owner is not whether to copy the home-tilt — it cannot, by mandate — but what to do about the second-order effects.

Three places to look. First, liquidity premia in non-US developed equities. If Korea, the UK, Japan and Canada all formally retain more domestic equity, the bid for marginal foreign listings drops — that should widen liquidity premia in mid-cap EAFE and in cross-listed names, all else equal. Second, private-market co-investment supply. The packaging of large LP co-investment vehicles by the bulge bracket — most visibly Goldman Sachs's PECP IV, which closed at over $2.8bn earlier in 2026 — is the structural answer to mega-allocators wanting more private-market exposure without losing fee discipline; expect more of it, and price it accordingly into manager negotiations. Third, governance of the home-tilt itself. The interesting question for a board is not "do we tilt home" but "do our policy mandates have the same kind of explicit asset-allocation reserve power the UK now has — and if so, who holds the trigger and what stops it being used pro-cyclically." A universal owner cannot diversify away from political risk to its own policy mix.

What to watch next

NPS vote today (Thursday, May 28, 2026) — formal 2027–2031 target ranges and any new upper bound for domestic equities.
GPIF policy-mix review — Japan's next five-year mix discussion is expected to come into clearer view through the summer; the JGB market is the constraint.
UK reserve power — the first ministerial guidance on conditions for triggering the Pension Schemes Act 2026 power is due ahead of the January 2028 earliest-trigger date.
IIF mid-year Capital Flows Report — the next read on whether private EM flows have actually decoupled from official flows.
