Morgan Stanley believes equity financing pressure could trigger quarter-end deleveraging and maintains the SFRZ6M7 flattener trade

Overview

This is a Morgan Stanley U.S. rates strategy report. Its core judgment is that equity financing conditions deteriorated ahead of quarter-end, especially after semiconductor sector earnings, intensifying the imbalance between leveraged longs and prime broker balance sheets and potentially triggering deleveraging in risk assets. In contrast, quarter-end pressure in the U.S. Treasury repo market appears relatively mild, shifting market focus from traditional repo stress to equity financing stress.

Core views

The report argues that an abnormal rise in equity financing costs raises the hurdle for leveraged long positions and may force some investors to reduce exposure. If this micro financing pressure further tightens macro financial conditions, the market will lower its confidence in the overheating economy and further Fed hikes, reducing the pricing of hawkish tail risk. The report also presents two pathways supporting SOFR curve flattening: first, if the Fed hikes in line with the dot plot, the market may see it as a policy mistake; second, lower Brent oil prices and declining inflation swaps reduce the probability of a persistent oil price risk premium.

Analysis framework

By comparing quarter-end stress in Treasury financing versus equity financing, observing extreme AXW equity financing costs, analyzing the leverage fragility of the S&P 500 and crowded semiconductor/AI trades, and combining Fed policy communication, proxy policy rates for financial conditions, core PCE forecasts, CPI inflation swaps, and Brent oil price moves, the report derives its strategy conclusion to maintain the SFRZ6M7 curve flattener.

Methodology notes

• Financing pressure analysisAXW equity financing costs and Z-score extremes

  AXW futures are used to measure the spread of the implied equity financing rate in S&P 500 total return futures relative to SOFR or the federal funds rate.

  The report treats AXW rising above 2 standard deviations of its rolling range as an abnormal signal of equity financing stress, and argues that historically such extremes are often followed by mean reversion in S&P 500 performance.

• Money market comparisonQuarter-end divergence between Treasury repo and equity financing

  By comparing UST GC repo, the SOFR-IORB relationship, reserve adequacy, and AXW equity financing costs, the report distinguishes the sources of stress across funding markets.

  The report argues that the Treasury repo market remains in an environment of relatively ample reserves, so SOFR should stay within the target range; by contrast, the equity financing side is more vulnerable because of leverage demand and balance sheet constraints.

• Monetary policy analysisProxy effective federal funds rate

  Morgan Stanley uses a method similar to that of the San Francisco Fed, incorporating 12 financial variables including Treasury yields, mortgage rates, and borrowing spreads into an index to measure the degree of policy tightening implied by financial conditions.

  The report says that since the Iran conflict, financial conditions have tightened by an amount equivalent to nearly four 25bp hikes, and are about 75bp tighter than the policy stance the June FOMC had just deemed appropriate.

• Fed reaction functionDot plot, forward inflation, and policy mistake risk

  The report compares the FOMC dot plot, core PCE forecasts, CPI inflation swaps, and Fed communication to judge whether the market is overpricing hike risk.

  The report argues that forward-looking inflation is weakening, and if the Fed still hikes according to the dot plot, the market may view it as a policy mistake, supporting repricing in front-end rates and curve flattening.

Asset mapping & comparison

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

• SFRZ6M7 SOFR curve flattener

  Core trade recommendation

  Strengths

  Benefits from the market reducing Fed hawkish tail risk, stronger relative performance of M7 versus Z6, and repricing of policy expectations after tighter financial conditions.

  Weaknesses

  If equity financing pressure eases quickly, growth data remains strong, or the Fed maintains hawkish communication, the flattener may lack a catalyst.

  Comparison

  The report sees this trade as an attractive way to express the market's overpricing of Fed hawkish tail risk.

  Risks

  Strong employment or inflation data, actual Fed hikes, a rebound in the oil risk premium, or continued gains in risk assets after quarter-end could all hurt the trade.

• Long 2-year (Sep '27) UST SOFR swap spreads

  Companion trade recommendation

  Strengths

  The report maintains the long, targeting a move from -10.4bp toward -9bp.

  Weaknesses

  This trade is relatively sensitive to front-end rates, the financing environment, and technical factors in swap spreads.

  Comparison

  Compared with the SFRZ6M7 flattener, this trade has more direct exposure to spread normalization in 2-year UST SOFR swap spreads.

  Risks

  The stop-loss is -15bp; if spreads continue to widen negatively or financing pressure transmits differently, the trade could lose money.

• Crowded longs in the S&P 500, semiconductors, memory, and global AI-related names

  Assets transmitting financing pressure

  Strengths

  Previously supported by rising risk assets, leverage expansion, and concentrated long demand.

  Weaknesses

  Higher financing costs raise the hurdle for maintaining leveraged longs, and tighter prime broker balance sheets may force position reductions.

  Comparison

  The report argues that equity financing pressure has a historical association with local highs in the S&P 500, and after AXW extremes the index is more prone to reverting toward a normal distribution.

  Risks

  If financing costs remain elevated, crowded trades such as semiconductors and AI could become concentrated zones of deleveraging stress.

• UST GC repo and SOFR

  Reference funding market

  Strengths

  Quarter-end GC repo pricing is relatively mild, and an environment of ample reserves helps keep SOFR within the target range.

  Weaknesses

  Quarter-end pricing may contain excess premium, and the repo market is still affected by quarter-end balance sheet management.

  Comparison

  Compared with equity financing pressure, the report sees the Treasury repo side as more benign.

  Risks

  If repo stress unexpectedly widens and pushes SOFR higher, it could alter the report's view of divergence across funding markets.

• Brent crude oil and the inflation risk premium

  Macro variables affecting Fed hawkish tail risk

  Strengths

  Lower Brent prices and falling CPI inflation swaps support the view that upside inflation risk is declining.

  Weaknesses

  Oil prices remain affected by geopolitics and supply disruptions.

  Comparison

  The report argues that the market may be underestimating the impact of lower oil prices on inflation expectations while overestimating optimism about U.S. growth.

  Risks

  If the oil price risk premium becomes persistent again, inflation expectations could rise and weaken the curve-flattening thesis.

Key data

• Quarter-end UST GC repo pricing3.75/3.72The report sees this pricing as implying relatively mild quarter-end stress in the Treasury repo market.
• 1-month AXW futuresAbout +200bpThe July 2026 contract rose to this level before the June 30 quarter-end, close to the year-end financing squeeze highs of December 2024.
• AXW extreme thresholdAbove 2 standard deviationsThe report says AXW-related indicators are already above the abnormal range of the past 12 months or 252-day rolling window.
• Equivalent tightening in financial conditionsNearly four 25bp hikes; about 75bp tighterThe report says financial conditions since the Iran conflict have tightened materially and are tighter than the policy stance the June FOMC had just judged appropriate.
• Core PCE forecast0.17% m/m; about 2.0% annualized in 2HMorgan Stanley economists expect average monthly core PCE growth of 0.17% for the remaining months of this year, below the 0.21% implied by the SEP.
• U.S. CPI inflation swapsBoth 1y and 1y1y below 2.5%; 1y near 2.00%The report argues that market-implied inflation has fallen rapidly, indicating lower upside inflation risk.
• SFRZ6M7 curve flattenerEntry about -0.5bp; target -10bp; trailing stop 10bpThe report explicitly recommends maintaining this trade.

Impact & implications

If equity financing pressure continues to intensify, leveraged longs could shift from being a force that previously drove risk assets higher to becoming an amplifier of declines. For the rates market, deleveraging and tighter financial conditions would weaken optimism on growth and pricing of tail risk for hikes, benefiting the SFRZ6M7 flattener. For U.S. equities, crowded trades in semiconductors, memory, and global AI-related names are more vulnerable to higher financing costs and tighter prime broker balance sheets.

Risks

• If equity financing costs do not decline after the June 30 quarter-end, this may signal that a larger deleveraging event is still unfinished.
• Prime brokers tightening financing supply because of GSIB surcharge capital constraints and internal risk budgets could amplify volatility in risk assets.
• If the Fed hikes in line with the dot plot, it may further push up front-end rates in the near term and hurt the flattener trade.
• If U.S. employment, consumption, or inflation data come in stronger than expected, the market may reinforce the overheating-economy and hawkish-Fed narrative.
• If Brent oil prices or Middle East geopolitical risks rise again, the inflation risk premium could return.
• If stress in the Treasury repo market unexpectedly intensifies and pushes SOFR higher, the report's divergence view of 'stable Treasury financing, tight equity financing' would be challenged.

What to watch

• Whether longer-dated equity financing costs such as 1-month AXW and AXW3 normalize after the June 30 quarter-end.
• Market breadth, position concentration, and signs of leveraged deleveraging in the S&P 500, semiconductors, memory, and global AI-related assets.
• Whether UST GC repo, the SOFR-IORB spread, and reserve adequacy continue to show benign conditions on the Treasury financing side.
• Whether next week's June employment data shows the payback after the strong May print described in the report.
• Whether monthly core PCE growth comes in close to Morgan Stanley's forecast of 0.17% m/m rather than the 0.21% implied by the SEP.
• Whether 1y and 1y1y U.S. CPI inflation swaps and Brent oil prices continue to decline.
• Whether FOMC officials' remarks on the dot plot, forward guidance, and policy flexibility reduce the tail risk of further hikes.
