A what‑if from the future

What if quantitative tightening drains reserves too low and forces the Fed to reverse course?

Quantitative tightening drains reserves below the ample threshold, spiking funding rates and forcing the Fed to halt QT and resume reserve-management purchases.

The butterfly cascade

How this trigger trickles across markets, left → right — the root shock, its first‑order moves, then the ripple effects. Drag any node; tap a market for its real price history.

Resolution timeline — how this probability is moving

Our model's odds (gold) over time vs the crowd's (Polymarket, blue), from the past toward the 6–18 months horizon. Each dot is a real macro event that nudged the probability — green pushed it up, red pushed it down. Tap a dot for the source. The gold path is an illustrative reconstruction anchored to today's estimate — real dated events, not a live re-estimate history.

What it would mean

If this plays out, it is a mixed shock. Quantitative tightening drains reserves below the ample threshold, spiking funding rates and forcing the Fed to halt QT and resume reserve-management purchases. The trigger decomposes into signed root‑shocks — Fed policy path ▼ · Financial conditions ▲ · Real yields ▼ — which propagate through our causal graph to the markets below.

If it happens — the markets it would move

Biggest moves first. Projected moves are cascade-model priors; hist A–B% = what comparable past events actually did (measured abnormal returns), and model prior · unmeasured marks markets with no analogue backing yet. Tap any market for its price history.

Probable recommendation

If the scenario above plays out, the probable cross‑asset positioning → a scenario‑conditional read, not personalized investment advice
For a common-man portfolio: Mixed for a typical portfolio — the move is more about rotation than direction. Favour the winners over the losers below rather than net exposure.
Also moves (not yet on Hyperliquid): Tech sector +0.7% · 30y Treasury yield -5bp · 10y Treasury yield -5bp · Homebuilders +0.3% · 2y Treasury yield -2bp · Turkish lira +0.2%

Historical precedent — what analogous events actually did

Across 25 analogous events (overlap‑weighted), as abnormal returns — market beta stripped, so it's the event's own effect, not the market backdrop. Shown at 20 days (persistent) and 5 days (immediate); ↺ fades = the two horizons disagree. Confidence = consistency × sample × significance.
