Equity financing pressure remains high, but the risk of spillover into UST funding markets is limited

Overview

This report focuses on the U.S. funding market "Super Tuesday" and centers on how major banks' earnings guidance affects capital accumulation, debt issuance, and equity-funding capacity. The authors argue that while short-end implied equity funding rates after quarter-end have normalized, financing costs remain elevated across year-end, indicating leveraged positions still face funding-cost risk. At the same time, current U.S. reserves are still ample, and the behavior of SOFR and TGCR relative to IORB does not indicate UST repo cash scarcity, while Fed RMPs and sponsored repo provide an important cushion.

Core views

The core view is that equity-funding pressure is real and linked to broker-dealer balance-sheet capacity, bank capital allocation, narrow market leadership, and leverage demand in semiconductor and AI-related sectors; however, the probability of significant spillover into UST funding markets is relatively low. The report expects that if banks add CET1 through retained earnings, issue senior debt, and allocate more balance-sheet capacity to prime brokerage, AXW futures may underperform, thereby easing equity-funding tightness. Strategically, the authors remain constructive on the SFRM7M8 curve steepener and believe softer labor-market and core CPI data support a reduction in recent Fed hike-risk premium.

Analysis framework

The report uses AXW futures to measure implied S&P 500 total return futures equity-funding rates versus floating-rate pressure and combines this with MMF AUM and commercial bank deposits relative to S&P 500 free-float market cap, primary dealer equity repo exposure relative to market cap, SOFR/TGCR versus IORB spread, commercial bank reserve-to-asset ratios, and sponsored repo scale to gauge equity-funding pressure, dealer balance-sheet constraints, and spillover risk to UST repo.

Methodology notes

• Funding Market Stress MonitoringAXW futures year-end turn analysis

  Use January AXW contracts to observe year-end equity-funding pressure

  The January AXW contract covers the year-end transition period; the report compares the 2027 January contract with 2024, 2025, and 2026 contracts to assess how market prices year-end 2026 equity-funding pressure.

• Reserve AbundanceSOFR/TGCR versus IORB and Reserve Demand Elasticity

  Judge whether the UST funding market is cash scarce by using money-market rates and bank reserves-to-assets as gauges

  SOFR and TGCR remain below IORB recently, and the reserve-to-commercial-bank-assets ratio is in a comfortable/ample range, indicating limited sensitivity of FFR and repo rates to changes in reserves.

• Leverage DependenceDealer equity repo exposure / S&P 500 free float market cap

  Measure equity-market dependence on dealer financing using primary dealer equity repo exposure relative to S&P 500 free-float market cap

  This proxy has risen sharply over the past year and is at record highs, indicating that each dollar of index market cap is backed by increasingly larger dealer financing exposure.

• Market Structure BufferSponsored repo netting capacity

  Use sponsored repo to assess Treasury repo intermediation capacity when balance sheets are constrained

  Sponsored repo can convert bilateral repos into centrally-cleared, easier-to-net-settle transactions, reducing total balance-sheet usage and expanding MMF cash accessibility, thereby buffering the transmission of equity-funding squeezes to Treasury repo.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• AXW futures

  Core market price signal for measuring equity-funding pressure

  Strengths

  Can directly reflect year-end equity-funding costs and dealer balance-sheet scarcity pricing.

  Weaknesses

  Affected by year-end effects, market concentration, and dealer capital allocation, so it cannot by itself explain UST repo cash supply-demand.

  Comparison

  The 2027 January contract is above the same period in prior years, indicating persistent pricing of 2026 year-end pressure.

  Risks

  If bank capital replenishment and debt issuance meaningfully increase funding supply, AXW may trade lower; if leverage demand continues to expand and concentrate, it may rise again.

• UST repo / SOFR / TGCR

  Used to assess whether equity-funding pressure is spilling into the U.S. Treasury funding market

  Strengths

  SOFR and TGCR remain relatively below IORB, indicating the current state is not one of cash scarcity.

  Weaknesses

  Month-end, large Treasury net settlement flows, and dealer intermediation capacity constraints can still cause short-term volatility.

  Comparison

  Unlike the GSIB-related year-end pressure in December 2024, current pressure is more tied to concentrated stock-market leverage rather than broad macro deterioration.

  Risks

  Repo rates could still rise temporarily if reserves fall more than expected or if sponsored repo capacity is insufficient.

• SFRM7M8 curve steepener

  Primary SOFR futures curve trade recommended to maintain

  Strengths

  Benefits from a decline in recent Fed hike-risk premium and has good alignment with the UST 7s30s steepener view.

  Weaknesses

  Trade performance depends on continued core CPI and labor data supporting a non-tightening Fed posture.

  Comparison

  The authors previously switched recommendations from SFRZ6M7 flatteners to SFRM7M8 steepeners.

  Risks

  If inflation data reignites a hawkish Fed tail risk, the curve may flatten again and the stop could be triggered.

• S&P 500 / Semiconductors and AI-adjacent equities

  Main source of equity-funding demand and leverage concentration

  Strengths

  Strong price performance attracts leveraged longs and drives financing demand.

  Weaknesses

  Market leadership has narrowed, and marginal buyers depend more on dealer funding, increasing deleveraging sensitivity.

  Comparison

  The report argues recent financing pressure is more driven by narrow market concentration than broad macro improvement.

  Risks

  If financing costs rise further or dealer balance-sheet capacity is insufficient, these sectors may face more pronounced deleveraging pressure.

Key data

• 2027 January AXW futures+90bpCovers the 2026 year-end transition, down from the quarter-end high but still elevated versus same period in prior years.
• MMF AUMabout $8.4trThe report stresses this is not equivalent to immediately investable "offshore cash" for equity buying, as a meaningful portion belongs to institutional, corporate, or lower-risk-preference household funds.
• SOFR and TGCR3.53% and 3.51% on 2026-07-09Roughly FF lower bound +3bp and +1bp, respectively; both 20-day averages remain around 2bp and 4bp below IORB.
• Ample/Comfy reserve thresholdReserves around 12%-13% of commercial banks' total assetsThe report cites the Fed RDE framework, which treats this range as the region where the reserve-demand curve is relatively flat.
• Equity-funding dependence proxyUp about 50% over the past yearThe proxy of primary dealer equity repo exposure relative to S&P 500 free-float market cap has increased significantly.
• OFR estimate on central clearingAverage daily Treasury repo central clearing share could rise from 45% to 77%, and add about $207bn in extra repo net-settlement capacity for six U.S. G-SIBsThis is roughly $34.5bn in additional capacity per G-SIB on average.
• SFRM7M8 steepener tradeMaintained at -17bp entry, -4bp target, -26bp initial stopUsed to reduce Fed hike-risk premium and aligned with the core UST 7s30s steepener view.
• 2-year UST SOFR swap spread tradeMaintain Sep '27 2-year UST SOFR swap spread long, around -10.5bp, target -9bp, trailing stop -15bpRisks include stronger-than-expected financing conditions or labor-market stabilization.
• UST 7s30s curve tradeMaintain DV01-neutral steepener, around 63bp, target 100bp, stop 50bpMain risk is renewed hawkish tail risk for the Fed if inflation data reignites concerns.

Impact & implications

For investors, the implication is that equity markets remain highly sensitive to financing costs, especially as leveraged longs are concentrated in semiconductors, storage, and global AI-related sectors, and bank balance-sheet allocation and capital guidance can directly affect financing costs and deleveraging risk. In the UST funding market, however, current evidence supports a "limited spillover risk" rather than "systemic cash scarcity": ample reserves, Fed purchase and repo facilities, and the sponsored repo net-settlement mechanism together reduce the probability of repo-market stress from equity-funding squeezes.

Risks

• If core CPI or other inflation data come in stronger than expected, this could again lift hawkish Fed tail risk and weaken the steepener trade.
• If the labor market stabilizes or re-strengthens, confidence in the Fed staying on hold may diminish.
• If bank earnings guidance shows insufficient capital build, debt issuance, or prime brokerage balance-sheet allocation, equity-funding costs may stay elevated.
• If narrow market leadership and semiconductor/AI-related leveraged trading continue to expand, financing-squeeze and correlation-driven deleveraging risks may increase.
• If reserves decline, Treasury settlement pressure, or dealer balance-sheet constraints exceed expectations, equity-funding pressure could still transmit to Treasury repo temporarily.

What to watch

• On July 14, capital accumulation, CET1 targets, debt issuance plans, and prime brokerage funding-capacity guidance in the earnings of five G-SIB banks.
• June CPI, especially core CPI month-over-month prints; Morgan Stanley economists expect the core print to remain soft at around 0.22% m/m, while MSCPIFIX points to about 0.26% m/m.
• The SOFR, TGCR, and IORB spread, and whether 20-day moving averages continue to indicate ample reserves.
• Whether the reserve ratio to total commercial bank assets stays near the 12%-13% ample/comfy threshold.
• AXW futures, especially the 2027 January contract covering the 2026 year-end transition.
• Sponsored repo volumes and repo-market behavior around month-end report days and large Treasury net-settlement dates.
• Performance of semiconductors, storage, and global AI-related equities, and whether it moves in sync with the equity-funding dependence proxy.
