Federal Reserve Study: For Every Dollar Increase in Treasury Issuance, Primary Dealer Balance Sheets Expand by an Average of 21 Cents

FEDS Notes released by Board of Governors staff members Glicoes, Petrasek, Saravay, and Tian quantify the mechanical impact of Treasury issuance on primary dealer balance sheets: dealer balance sheets expand by an average of 21 cents per dollar of issuance on issuance dates, with this effect tending to be larger during Federal Reserve balance sheet runoff periods. The study further traces how this balance sheet expansion translates into constraints on the Supplementary Leverage Ratio (SLR) and consumption of Value-at-Risk (VaR) risk budgets.

Jonathan Glicoes, Lubomir Petrasek, Zack Saravay, and Mary Tian, staff members of the Board of Governors of the Federal Reserve System, published FEDS Notes titled "Treasury Issuance and Dealer Balance Sheets" on October 30, 2026. The paper quantifies the mechanical impact of Treasury issuance on primary dealer balance sheets and its amplification during balance sheet runoff periods. The core finding is that on issuance dates, primary dealer balance sheets expand by an average of 21 cents for every dollar of Treasury securities issued; this effect tends to be larger during periods when the Federal Reserve is reducing its balance sheet.

The mechanism operates as follows. When Treasury auctions settle, winning dealers must finance the securities they acquire, while client purchases also increase dealers' financing needs. Consequently, dealer balance sheets exhibit observable expansion on issuance dates. Using data from the FR 2052a Liquidity Monitoring Report, the study regresses daily changes in dealer holdings and repo volumes against daily issuance amounts. It finds a coupon issuance coefficient of 0.08 (meaning each dollar of issuance leads to an 8-cent change in holdings) and a bill issuance coefficient of 0.05.

How does balance sheet runoff amplify this effect? When the Federal Reserve itself reduces its balance sheet, Treasuries previously held by the central bank must be absorbed by the market. As market-makers and intermediaries, primary dealers take on a larger share. The study finds that during QT1 (Quantitative Tightening phase 1), dealer sensitivity to each dollar of coupon issuance increased by an additional 3.3 cents compared to non-QT periods; during QT2, dealer sensitivity for both repo and reverse repo increased by approximately 13 cents each for every dollar of coupon issuance compared to non-QT periods. This indicates that balance sheet runoff not only reduces securities directly held by the central bank but also transforms supply pressure into balance sheet expansion through dealer channels.

How does this balance sheet expansion translate into actual constraints? Extrapolating the average 21-cent effect: if quarterly coupon issuance volume reaches $1 trillion, primary dealer balance sheets would collectively expand by approximately $210 billion on issuance dates. Assuming this effect unwinds within 5 days following auctions, the average quarterly impact on the denominator of the Supplementary Leverage Ratio (SLR) for dealers would be about $17.5 billion; considering the higher persistence of repo financing, calculated over 10 days, the impact would be approximately $35 billion. The SLR is a leverage constraint imposed on large banks under Basel III; an expanded denominator directly compresses the risk budget available for dealers to engage in market-making.

Evidence of risk budget consumption is equally clear. The study regresses average VaR usage on U.S. Treasury market-making desks against issuance volumes. In a model controlling only for interest rate volatility (the MOVE index), the issuance coefficient is 0.025 and statistically significant; after further adding buyback operations and long Treasury positions as control variables, the issuance coefficient drops to 0.012 but remains significant. The buyback coefficient is negative (-0.005 in the model including buybacks, and -0.013 in the model including both buybacks and long positions), indicating that buybacks partially release dealers' risk capacity.

The practical significance of this research framework lies in moving the discussion of how Treasury issuance consumes dealer market-making capacity from qualitative debate to quantifiable estimation. The study's introduction notes that recent increases in Treasury issuance have raised market concerns about whether dealers can meet intermediary demand; the coefficients derived above provide an empirical basis for assessing this constraint.

Boundaries to note: FEDS Notes explicitly state that they represent the personal views of staff members and do not constitute policy positions. The study relies on historical data regressions, and extrapolating coefficients depends on the assumption that future issuance structures (proportions of coupons vs. bills, buyback rhythms) resemble the sample period. Dealers may partially alleviate constraints by adjusting inventory strategies, seeking alternative financing channels, or altering market-making quote behaviors; static SLR denominator calculations may overestimate actual pressure. Furthermore, the QT phases covered in the sample period may differ from future balance sheet reduction or expansion paths.
