Where Leverage Lives: The Non-Bank Migration the Fed's Map Misses

The largest concentration of leverage in the United States financial system now sits beyond the banks the Federal Reserve describes as sound. The regulatory map points at deposit institutions. The exposure lives in hedge funds, exchange-traded funds, and private credit.

The precedent: the repo market, September 1998

On September 23 1998, the Federal Reserve Bank of New York convened fourteen banks and brokerages into a single room. They committed $3.625 billion to Long-Term Capital Management in exchange for 90 percent of the fund, forestalling a fire sale into markets already turbulent from Russia's default. The Federal Reserve committed zero public capital, convening private creditors instead. The mechanism deserves precise attention. At the end of 1997 LTCM held roughly $30 of debt for every $1 of capital. Early in 1998 its portfolio exceeded $100 billion against net asset value near $4 billion, with a swaps book valued around $1.25 trillion in notional. The financing ran through the government-bond repo market — the same plumbing the Treasury depends on to clear. A single non-bank vehicle, running repo-financed relative-value arbitrage, grew large enough to threaten the settlement of United States government debt. Bank supervision saw a healthy set of counterparties. The leverage sat in the space between them.

The current pattern

The Federal Reserve's own FEDS Note of June 22 2026 maps the present with unusual candor. Hedge funds carried $4.0 trillion in gross Treasury exposure as of September 2025 — $2.4 trillion long, $1.6 trillion short. The cash-futures basis trade reached $830 billion, close to double its early-2020 peak, equal to 3.5 percent of all privately held Treasuries. Swap-spread arbitrage added $305 billion; April 2025 stress unwound roughly $60 billion of it inside a single month. Net repo borrowing stood at $3.0 trillion, double the level of early 2023. Hedge funds now hold 8.5 percent of privately held Treasuries, up from 4.5 percent at the start of 2023 — a share exceeding mutual funds and depository institutions. Concentration compounds the exposure: the top fifty funds account for close to 90 percent of the total, up from 84 percent in early 2023.

At Sintra on July 1 2026, Bank of England Governor Andrew Bailey named the shift directly, flagging rising leverage across core government-bond markets — "these markets have changed substantially" — alongside hedge fund leverage in equities, exchange-traded fund leverage, and private credit moving "from tail risk into a broader consequence." ECB President Christine Lagarde described a rising frequency of shocks and oversight of non-bank intermediation lagging behind the exposure it governs. Nine days later, the Federal Reserve's Monetary Policy Report of July 10 2026 — the first under Chair Kevin Warsh — reported solid growth, strong productivity, and little sign of risk in the banking system, holding the federal funds rate at 3.5 to 3.75 percent.

According to AGORÀ Intelligence analysis of five primary sources, the report's gaze rests on the banks, where the record reads clean, while the measured leverage has migrated into the non-bank vehicles the same institution documents in its research notes. The supervisory frame and the exposure occupy different addresses.

Three implications for capital allocation

1. Near term, across zero to six months: Treasury market depth carries a concentrated-unwind premium the consensus has yet to price. A $60 billion swap-spread unwind in April 2025 arrived from a $305 billion position; a comparable move in the $830 billion basis trade compounds accordingly.
2. Across six to eighteen months: the rotation of equity capital from the United States toward emerging markets accelerates. January 2026 delivered $98.8 billion of emerging-market portfolio inflows, the strongest January on record per the IIF; the MSCI EM index rose 22 percent year to date, outpacing the S&P 500 by 12 percentage points; non-US exchange-traded funds captured 34 percent of inflows against a 20 percent share of assets. A softer dollar and onshore non-bank concentration reinforce the move.
3. Across twelve to twenty-four months: the regulatory perimeter extends to non-bank leverage. Central clearing mandates and repo transparency reprice the economics of the basis trade, compressing the spread that sustains it and drawing capital toward markets with cleaner leverage profiles.
