Japan’s Government Pension Investment Fund (GPIF) currently targets 25% each in domestic bonds, foreign bonds, domestic equities and foreign equities. The mix began in April 2025. At March 31, 2026, the four reported weights were close to those targets—26.91%, 24.48%, 23.81% and 24.80%, respectively—but they are not four separate bets reset every day. They are a long-term policy mix managed within published tolerance bands.
The practical takeaway is simple: read GPIF’s target mix, the actual weights and the classification notes together. A headline that says the fund is “50% equities” is broadly right, but it misses how currency-hedged foreign bonds, short-term assets and alternatives are treated in GPIF’s reporting.
Key takeaways
- GPIF’s policy asset mix is 25% in each of four classes: domestic bonds, foreign bonds, domestic equities and foreign equities.
- The current mix applies from April 2025 through the fifth medium-term objective period, which runs to March 2030.
- At March 31, 2026, GPIF reported ¥299.8 trillion for the overall pension reserve fund in this allocation table; domestic bonds were the largest of the four reported sleeves at 26.91%.
- The policy mix is a risk-management framework, not a forecast that any one market will rise or fall.
- Alternatives are not a fifth target bucket in this presentation, and hedged foreign bonds can be classified with domestic bonds. Those details matter when comparing GPIF figures with a standard retail portfolio chart.
What GPIF’s policy asset mix actually targets
GPIF is Japan’s Government Pension Investment Fund, the public institution that manages pension-reserve assets. Its policy asset mix is the long-term allocation framework it uses to pursue the required real return with minimum risk; it is not a list of four funds for an individual investor to copy.
The fund says the current framework started in April 2025 and is designed to target a 1.9% real return—net investment yield less nominal wage growth—with minimum risk. The target is even across the four reported asset classes, but the permitted movement around each target is not identical.

| Reported asset class | Policy target | Permitted deviation for the class | What the label includes |
|---|---|---|---|
| Domestic bonds | 25% | ±6 percentage points | Yen-hedged foreign bonds and yen-denominated short-term assets are classified here. |
| Foreign bonds | 25% | ±5 percentage points | Foreign-currency short-term assets are classified here. |
| Domestic equities | 25% | ±6 percentage points | Japanese listed-equity exposure and some alternatives classified by risk-return characteristics. |
| Foreign equities | 25% | ±6 percentage points | Overseas listed-equity exposure and some alternatives classified by risk-return characteristics. |

The important distinction is between a target and a limit. A 25% target does not mean each sleeve must read exactly 25.00% after every market move. GPIF can rebalance and manage within its disclosed bands; the report also says alternatives are classified into the four main asset classes by risk-return characteristics and are generally limited to 5% of total assets.
Actual weights at March 31, 2026

Worked reading example: the domestic-bond gap
The calculation is a position check, not a claim about a trade:
- Input: domestic bonds’ reported weight at March 31, 2026 = 26.91%.
- Policy target: domestic bonds = 25.00%.
- Formula: 26.91% − 25.00% = +1.91 percentage points.
- Interpretation: the sleeve was above its target on that date, but still inside the published ±6 percentage-point class band. It does not by itself show that GPIF made a directional call on Japanese rates or that a reader should expect a transaction.
That distinction is especially useful when assessing Japan’s bond market. GPIF’s own results materials say that asset prices, exchange rates and rebalancing all affect reported weights. For broader rate context, see ATG Press’s Japan 10-year government bond yield guide.
Why four equal targets do not mean four equal exposures
The 25-25-25-25 presentation is intentionally simple, but two reporting choices keep it from being a literal four-box portfolio.
First, GPIF classifies foreign bonds with currency hedges and yen-denominated short-term assets as domestic bonds; foreign-currency short-term assets are classified as foreign bonds. In other words, a label reflects the fund’s risk-management classification, not just the issuer’s address.
Second, infrastructure, private equity, real estate and other approved alternatives are not shown as an independent strategic bucket. GPIF classifies them into the four main categories by risk-return characteristics. At March 31, 2026, alternatives were 1.74% of the overall pension reserve fund, within the stated 5% maximum.
This helps explain why a simple scan of GPIF’s top holdings or a domestic-versus-foreign split will not reproduce every number in the policy-mix chart. The correct order is: identify the reporting date, use GPIF’s classification, then compare actual weights with the relevant band.

How to use GPIF’s releases without over-reading them
GPIF’s annual report and quarterly update reports are useful reference points for Japan’s long-term institutional-investor backdrop. They are not a signal service for a particular security or a substitute for a portfolio policy.
Use this short reading sequence when a new GPIF result arrives:
- Check the reporting period and date. A fiscal-year report, quarter-end portfolio table and current market level answer different questions.
- Separate policy target from actual allocation. A deviation can result from market movements, flows, currency moves or rebalancing.
- Read the classification notes before adding asset categories together, especially for hedged foreign bonds, short-term assets and alternatives.
- Compare a return with its benchmark and stated period, rather than treating a one-year result as a permanent run rate.
- Keep the public-policy context separate from an individual stock thesis. GPIF generally uses external asset managers for individual equity selection rather than directly selecting equities itself.
GPIF reported a 16.47% FY2025 return and ¥41.4 trillion of return in its July 3, 2026 summary, but it also stresses that results should be assessed over a long horizon. Those reported figures explain the period; they are not a forecast for FY2026.
What to watch next
The next useful checkpoints are GPIF’s FY2026 quarterly update reports, any formal policy-mix review, and the fund’s notes on risk limits and classification. The current mix is part of the April 2025–March 2030 medium-term period, but GPIF’s annual report says it verifies whether the assumed investment environment has changed and can consider a revision when necessary.
