New on FinoLib · Volume I: Global Economy
I have added a new article to FinoLib, my finance education website: Repo Market Explained, Plus Insurers and Pension Funds, part of Volume I: Global Economy. This page gives you the core of the topic in expert but plain language; the full article goes much deeper.
3.15 The Hidden Giants — Insurance and Pension Funds
The idea in plain words
Insurers and pension funds hold some of the largest pools of capital because their liabilities are long. In a defined benefit plan the employer carries the investment risk; in a defined contribution plan the worker does.
Key points
■At the end of 2024, pension funds held $44.1 trillion and insurance corporations $38.9 trillion of financial assets in the 29 jurisdictions the FSB tracks, together about a third of the $256.8 trillion broad non-bank total.
■A defined benefit plan paying 1.5% × 30 years of service × a final salary of $80,000 gives $36,000 a year for life.
■Putting $10,000 a year into a defined contribution plan for 30 years yields about $664,388 at 5% a year and about $475,754 at 3%; the worker absorbs the $188,634 difference.
A closer look
Banks dominate headlines, but the patient money belongs elsewhere. At the end of 2024, pension funds held $44.1 trillion and insurance corporations $38.9 trillion of financial assets in the 29 jurisdictions the Financial Stability Board tracks, together about a third (83.0 ÷ 256.8 ≈ 32%) of the FSB’s $256.8 trillion broad non-bank total. Their superpower is long liabilities: a pension promised to a 30-year-old comes due decades from now, so these funds can hold assets through crashes that would destroy a bank funded by instant-withdrawal deposits. That makes them the natural buyers of the long-term bonds (chapter 2.9: Bonds and the Yield Curve — The Market That Rules Them All) that finance governments and infrastructure, the anchor investors in IPOs, and the largest clients of the custodians and asset managers of Part 11: The Post-Trade World.
Recap
Insurers and pension funds hold some of the largest pools of capital because their liabilities are long. In a defined benefit plan the employer carries the risk (1.5% × 30 years × $80,000 = $36,000 a year), while in a defined contribution plan the worker does; leveraged hedging by DB funds can still force fire sales, as in the UK in 2022.
3.16 The Repo Market — The Financial System’s Overnight Plumbing
The idea in plain words
A repo is an overnight loan secured by bonds, with a haircut and daily margin. The plumbing failed in September 2019 and again in March 2020, when even Treasuries were hard to sell until the Fed intervened.
Key points
■A $100 million trade at a 2% haircut lends $98 million, and a 3% fall in the bonds triggers a $2.94 million margin call.
■SOFR, calculated from actual Treasury repo transactions, replaced LIBOR in 2023 and printed 3.87% on October 1, 2026.
■India’s headline policy rate is literally called the repo rate: on October 1, 2026, it was 5.25%, with the Standing Deposit Facility rate at 5.00%.
A closer look
Everything this Part has described — deposits, loans, capital markets, shadow banks — is funded, hour to hour, through a market that never appears in headlines when it works. In a repurchase agreement, a borrower hands over high-quality collateral (almost always government bonds — chapter 2.9: Bonds and the Yield Curve — The Market That Rules Them All) and receives cash; the next morning the trade reverses, with the borrower paying a sliver more to reclaim its bonds. That sliver, annualized, is the repo rate. Because the loan is fully collateralized by the safest assets on Earth — and usually over-collateralized, with the extra margin called a haircut — repo is among the cheapest borrowing available.
A worked example
Trace the Chain — Part 3 Thought Experiments
1. A rating agency cuts a large Indian NBFC (Non-Banking Financial Company — a finance company that lends like a bank but holds no banking license) from BBB− to BB+. Trace the forced-selling chain and who feels it last. 2. Everyone in a city tries to withdraw deposits on the same morning. Which chapter explains why no bank survives this unaided — and which institutions exist to stop it? 3. Explain to a friend why your grandmother’s LIC policy makes her, indirectly, a part-owner of Reliance. 4.
Recap
A repo is an overnight loan secured by bonds, with a haircut and daily margin; a $100 million trade at a 2% haircut lends $98 million, and a 3% fall in the bonds triggers a $2.94 million margin call. The plumbing failed in September 2019 (SOFR 2.43% to 5.25% in a day) and in March 2020, when even Treasuries were hard to sell until the Fed intervened.
