Wall Street Just Loaded Up on Treasuries to a Level Not Seen Since 2007

EBM Newsdesk Analysis

Wall Street’s primary dealers — the 25 banks and broker-dealers authorised to trade directly with the Federal Reserve — have lifted their US Treasury holdings to the highest level since 2007, according to data compiled by the New York Fed and reported by the Financial Times. The rise reflects the dual pressure of record US Treasury issuance to fund the federal deficit and continued Fed balance-sheet runoff, with dealers absorbing supply that no other buyer is prepared to take. The figure matters less for what it says about bank balance sheets than for what it reveals about the underlying capacity of the US Treasury market — the deepest and most strategically important fixed-income market on the planet, and the one European pension funds, insurers and central banks rely on as the structural backbone of global fixed income.

The deeper read is that primary dealers are holding more Treasuries than ever, but their capacity to intermediate the market is structurally smaller relative to its size than at any point in modern financial history. Since 2007 the volume of outstanding Treasury securities has grown nearly fourfold relative to total primary dealer balance sheets, a divergence that explains why almost every recent episode of bond market stress has been sharper, faster and harder to contain than past dislocations.

What the Number Actually Tells Us

The headline figure — primary dealer Treasury holdings at their highest level since 2007 — sounds like a return to pre-crisis normality. It is the opposite. In 2007, the Treasury market totalled roughly $5 trillion outstanding and dealers handled the vast majority of intermediation. In 2026, the Treasury market is approaching $30 trillion. Dealers absorbing record absolute amounts of paper while the market itself has multiplied in size means each dollar of dealer balance sheet is now stretched across a meaningfully larger pool of obligations.

The Federal Reserve’s own October 2024 staff analysis quantified it bluntly: the market value of Treasury securities held by the public has grown 176% over the past decade, while primary dealer gross Treasury positions have grown only 80% over the same period. Dealer secured financing for clients has grown just 43%. The intermediation gap is structural and widening. The post-2008 capital regime governing US bank balance sheets — particularly the Supplementary Leverage Ratio — was designed to make banks safer. The unintended consequence is that those same balance sheets are now too constrained to act as the elastic buffer the Treasury market historically depended on.

Why Dealers Are Holding More Anyway

The compression makes the current build-up more concerning, not less. Three forces are pushing Treasury holdings onto bank balance sheets simultaneously.

First, supply. The US Treasury is issuing debt at a pace driven by structural deficits north of 6% of GDP, with no political path toward narrowing. Every auction must clear, and dealers are the buyers of last resort.

Second, the Fed. Quantitative tightening continues to remove the central bank as a marginal Treasury buyer, transferring duration risk onto private balance sheets. Between June 2022 and late 2024, primary dealer gross positions grew 47% while the Treasury market itself grew only 31% — dealers absorbing an outsized share of the rebalancing.

Third, regulatory positioning. Large bank Treasury holdings have grown from 3% of total assets in 2013 to roughly 11% in 2024, partly because liquidity regulations actively reward them for holding Treasuries as high-quality liquid assets. Banks are simultaneously being told to hold more government debt for liquidity reasons and being prevented from intermediating it efficiently for capital reasons. The contradiction is now structural.

Why European Investors Should Care

For European institutional investors, the build-up has three direct implications. First, the basis trade — the highly leveraged hedge fund strategy of arbitraging Treasury cash and futures prices — is concentrated in Cayman Islands financial centres but counterparty-exposed to the same primary dealers now holding record positions. Bank for International Settlements estimates suggest the basis trade has grown to roughly $1 trillion in notional exposure, much of it sitting on the same balance sheets carrying these record Treasury positions. Any sharp dislocation in the basis trade now propagates faster and further into European fixed income than it would have a decade ago.

Second, ECB-Fed divergence. The ECB is still cutting rates while the Fed holds, leaving European fixed-income managers with structurally weaker yields than US Treasuries can offer. Euro Area holdings of US Treasuries have already risen to a record $2.0 trillion as of February 2026, according to Treasury Department data, with private foreign investors adding $461 billion over the past 12 months. European capital is flowing into the same paper Wall Street dealers are stockpiling — and that crowding into a single trade has historically preceded sharp reversals.

Third, market-functioning risk. The March 2020 Treasury market dislocation — when dealer balance sheets seized up under Covid stress — only resolved when the Fed launched emergency market-function purchases. The structural conditions that produced that dislocation have not improved. They have, by every available measure, worsened. A repeat episode would now hit a market with more outstanding paper, less proportional dealer capacity, and significantly larger basis trade exposure.

What to Watch Next

The key signals from here are three. First, whether the Fed signals any willingness to pause balance-sheet runoff to relieve dealer pressure — a quietly significant decision that would reverse the 2022 normalisation programme. Second, whether the Treasury alters its issuance mix to reduce the long-duration bills hitting dealer inventories most heavily. Third, whether US regulators move on Supplementary Leverage Ratio reform, which the Bank Policy Institute and major dealers have been quietly lobbying for since 2024.

For European pension funds and insurers managing duration exposure, the read is straightforward: the buyer of last resort in the world’s most important bond market is now structurally smaller than the market itself, holding more paper than at any point since the financial crisis. That is not a stable equilibrium. It is a system that requires either Fed intervention, regulatory reform, or eventually breaks.

Wall Street is loading up. Brussels and Frankfurt should be paying closer attention than they currently are.
