Real Money Investors: What the Term Means, and Who Gets Forced to Sell

"Real money" has no definition in the rule books we looked in. We use it here for pension funds, insurers, sovereign funds and the asset managers that buy without borrowing.

Hedge funds, which pool money for managers free to borrow and to sell short, are the usual comparison. Both sides can be forced to sell. What differs is what forces them. How fast it happens differs too.

We looked in the position-report notes of the US futures regulator and of a London futures exchange (ICE Futures Europe). We read the European rules on commodity positions and on alternative funds. We read the Bank for International Settlements survey guidelines and the Financial Stability Board's 2025 monitoring report.

The phrase appears in none of them.

Official statistics do divide the same investors, using labels of their own. The Bank for International Settlements counts "institutional investors" on one side and "hedge funds and proprietary trading firms" on the other. The US futures regulator uses "Asset Manager/Institutional" against "Leveraged Funds".

Those schemes disagree. ICE Futures Europe puts pension funds and hedge funds in one bucket called "Managed Money". The Bank for International Settlements puts central banks and sovereign wealth funds in a separate official-sector category, outside "institutional investors". The US futures regulator files central banks under "Other Reportables".

So no single official line exists to be drawn. What exists is a set of structural differences.

Pension funds held $44.1 trillion of financial assets at the end of 2024 and insurance corporations $38.9 trillion, against $11.3 trillion for hedge funds. Each bar covers 29 jurisdictions accounting for over 90% of world output.

Pension funds alone are 3.9 times the hedge fund pool. Pension funds and insurers together are 7.3 times it, on that one measure and date.

The chart leaves out the other funds on this side. On the same basis, investment funds other than money market, hedge and real estate funds held $69.1 trillion. Money market funds held $12.1 trillion. No official total exists for sovereign funds.

The chart shows size. Borrowing matters more. The rest below is about it.

The Bank for International Settlements survey guidelines set hedge funds apart as funds facing no restrictions on borrowing or derivative exposure, many using high levels of both. They sit under a different regulatory mandate from institutional investors.

A cap does exist on part of the other side. A UK retail fund of the UCITS type (a UCITS) may not borrow more than 10% of its scheme property on any day. The borrowing must be temporary. Its exposure through derivatives may not exceed the fund's net value.

That cap reaches neither pension funds nor insurers.

Hedge funds that file with the US securities regulator held $14.4 trillion of assets at the end of 2025, across 9,858 funds. After liabilities, $6.0 trillion was left for their owners.

Borrowings were 54.7% of the gross figure, about $7.9 trillion. The rest of the gap between the two totals is other liabilities. That is also a different date, scope and measure from the $11.3 trillion above, so those two are not comparable either.

Speed is the part that matters. Gilts are UK government bonds. Repo is a loan of days or weeks secured on them.

Hedge funds lean on repo funding more heavily than liability-driven investment funds do. A large share of their gilt borrowing matures in a week or less, so it needs constant refinancing. A lender can decline to renew it.

The line is not clean. On Federal Reserve data published in May 2026, borrowing and derivative exposure at the largest life insurers sat in the top quarter of its historical range. Supervisory data treat hedge funds, pension funds and insurers as three sectors that use high levels of both.

UK defined-benefit pension schemes, which owe their members a set income, hold gilts through liability-driven investment (LDI) funds to match those obligations. Those funds borrow, through repo or derivatives, to hold more gilts than the scheme could buy outright. More than £1 trillion was invested in LDI products in the UK at the time.

Thirty-year gilt yields then rose 140 basis points over the four days from 21 September 2022. A basis point is one hundredth of a percentage point. That was more than twice the largest such move since 2000 before it, which came in March 2020.

Falling gilt prices cut the value of the collateral behind the borrowing, so lenders called for more cash and margin fell due on the derivative positions. To raise it the funds sold gilts, which pushed yields higher and brought the next call.

The Bank of England described a vicious spiral of collateral calls and forced gilt sales. It called the result a material risk to UK financial stability.

Collateral and margin calls on LDI funds and pension schemes exceeded £70 billion by Bank staff estimate. Across non-bank sectors, variation margin on interest rate derivatives came to about £13 billion in that episode. Variation margin is the daily cash owed when a derivative position moves against the holder.

Between 23 September and 14 October 2022, defined-benefit schemes sold around £14 billion of gilts. Separately, LDI funds sold around £23 billion. The two figures cover overlapping groups, so they should not be added. The Bank of England bought £12.1 billion of conventional gilts and £7.2 billion of index-linked, £19.3 billion in all, between 28 September and 14 October.

Margin is not the only mechanism on this side. A mandate to hold investment-grade bonds could force a sale when a holding is downgraded. A fund dealing daily while holding less liquid assets may have to sell to meet redemptions.

Variation margin calls on non-bank sectors came to about £0.4 billion between 27 February and 9 March 2026, against roughly £13 billion in the autumn 2022 episode.

Hedge funds cut positions across European, UK and US government bond markets that spring. The triggers were the onset of the Middle East conflict and a reassessment of the path of policy rates. Their net gilt sales were sizeable, spread across a month, with an orderly adjustment.

The 2022 net sales by insurers and pension funds, before the Bank's intervention, were about half that scale. That is a different measure from the figures above. The heaviest of it fell inside a single week. That concentration overwhelmed market capacity.

Asset managers, insurers and pension funds bought what the hedge funds sold, alongside sterling cash lending from other investors. No gilt market operation followed. Part of the contrast is reform: since 2023 LDI funds have had to hold far more collateral against a stress.

One case is not a guarantee. A critical factor in 2026 was the supply of gilt repo, which cannot be assumed in a more severe shock.

The label also divides capital that is not divided in fact. At the end of 2025, state and municipal pension plans held $535 billion of the net assets of the largest US-reported hedge funds. Other pension plans held $428 billion.

Between them that is $963 billion of the $4,845 billion those funds hold for their owners, which is 19.9%. That is a narrower set of funds than the 9,858 counted above.

Sovereign wealth funds and foreign official institutions held $373 billion of those net assets, insurers $176 billion. With the pension plans that is $1,512 billion, or 31.2%. Close to a third of the money in those funds was put there by institutions on the other side of the label.

No rule book we read defines real money. None of them grants it immunity either. In the gilt market, borrowing that a lender can withdraw was the fastest route to a forced sale. That is why the forced seller in 2022 was the part of pension money that had borrowed.

This explainer is part of the YX Insights Academy. Each one takes a single idea and checks it against real data.

The same approach runs through everything else we publish:

Good places to start on the website:

No rule book we looked in defines it. We use it for pension funds, insurers, sovereign funds and asset managers that buy without borrowing. Official data uses "institutional investors" or "Asset Manager/Institutional" for roughly the pension fund, insurer and asset manager part of that group.

Hedge funds are not subject to the borrowing cap that binds UK retail funds of the UCITS type. Many borrow heavily. Borrowings were 54.7% of gross assets at the end of 2025 among funds filing with the US securities regulator. Much of that borrowing is repo maturing in a week or less, which a lender can decline to renew.

Yes. In autumn 2022, collateral calls on UK liability-driven investment funds produced what the Bank of England called a vicious spiral of forced gilt sales. The Bank bought £19.3 billion of gilts in response. Investment-grade-only mandates and fund redemptions can force sales too.

Pension funds and insurers together held 7.3 times the financial assets of hedge funds at the end of 2024, $44.1 trillion and $38.9 trillion against $11.3 trillion, across 29 jurisdictions. On the same basis, other investment funds held $69.1 trillion. No official total exists for sovereign funds.
