SPX -1.7%, CTAs to sell Another $35BLN

From the TightSpreads Substack.

Market Open Note

The market is selling off hard today with the SPX about -1.6% intraday. This is a meaningful selloff, but feels like it should be down more given three big negative catalysts stacking up:

1. Reduction in oil supply — Geopolitical escalation (US/Israel-Iran conflict entering its fifth day or so) has disrupted tanker traffic through the Strait of Hormuz, halted some production (e.g., Qatar LNG facilities hit), and created stranded tankers. Oil prices are surging (WTI likely well above recent levels), which is inflationary and growth-negative.

2. Limiting of private credit withdrawals — Major private credit funds (BlackRock’s $26B HPS Corporate Lending Fund, Blackstone’s BCRED) are imposing redemption gates/limits (e.g., capping at 5-7% quarterly) after massive outflows ($1.2B+ requests at BlackRock, $1.7B net at Blackstone). This signals stress in the $1.8T private credit market — retail/investor anxiety spilling over, forcing liquidity restrictions and potential forced selling or asset sales in credit-sensitive areas.

3. Negative NFP miss — February jobs data released this morning came in at -92K (down from prior +130K revised), way below expectations (~59K consensus). Unemployment likely ticked up, signaling labor-market softening after earlier resilience. This is a classic “bad news” print that questions soft-landing hopes and could push Fed cut pricing.

Bonds initially cushioned (yields dipped early) but have reversed (yields up 5 straight days), hurting risk-parity funds (which short bonds to buy equities). This cushion is now gone. Macro systematic strategies (Quant , CTA funds that are automatically buy or sell given market parameters) will have an incremental $10bn for sale from this morning’s selloff, bringing the total supply for the next week to $35bn (an overhang at a 1.2 z-score), which will grow in a down market.

Hedge funds are extremely well-hedged in SPX options — short put delta balance at all-time extremes (meaning lots of protective puts bought, dealers short those puts). But MTM losses on existing positions haven’t been fully monetized (closed out), so dealers are getting squeezed on their short vega positions (they are net short volatility exposure and have to buy vol as realized vol rises).

Result:

• VIX is spiking 3x as much as SPX is down — biggest vol outperformance on a -1%+ day since April 2025 (normal beta ~1.5x).

• Street is flat gamma overall but very long gamma on the upside (dealers buy strength aggressively near ~7020 peak long gamma, but short gamma downside at lower levels like 6675). This caps big rallies but risks acceleration lower if we break.

US equity L/S HF nets at 52% — not stretched (moderate bullish tilt), but not yet down to the 49-50% area where markets have historically bounced over the last year (when nets get that low, funds are defensive enough for a reversal).

The market is absorbing bad news without total panic (breadth may still be decent, rotation into defensives/HALO possible), but the $35bn systematic overhang + vol squeeze + private credit gates create downside fragility. If yields keep rising or oil spikes more, it could feed on itself.
