The RRP Drain Is Not Symmetric — Why It Matters for Gold
The Reverse Repo Facility has drawn down from $2.4 trillion to <strong>$481 billion</strong>. Standard reads treat this as outright liquidity tightening. The institutional read is more nuanced — RRP money moving into T-bills re-enters the system as active demand. The net liquidity effect depends entirely on where Treasury is absorbing the issuance.
Our <strong>USD Liquidity Score</strong> — SOMA holdings, RRP balances, and TGA levels — shows a net 4-week change of −$340B. Elevated but not extreme. Currently reading at −0.8σ from the 52-week mean. COT managed-money net z-score and COMEX delivery intentions are read in the same packet before any GC bias is set.

4-week rolling
The key variable is the Treasury General Account. When the TGA draws down, excess reserves flood the banking system regardless of QT pace — a divergent signal the regime engine flags before we size GC. Full packet includes dealer gamma above $3,100, GLD flow confirmation, walk-forward context from Sentinel, and execution bands across GC / MGC / XAU.

Market Codex — Separate product · excerpt in weekly briefing
What Matters This Week — Sun Through Friday
Market Codex is a separate product from The Quant Ledger. It may draw from some of the same sources, but it owns the <strong>current-week map</strong> — what matters now, day by day — while the Ledger publishes the validated research behind it.
Each week’s Quant Ledger briefing includes the Codex title run so members see how the live map and the gold research packet align. Below: this week’s Sun–Fri issue titles (sample format).
MonOpening Map — Fed Speak, Auction Supply, GC Gap Risk
TuePositioning Day — COT Print & ETF Flow Confirmation
WedMidweek Process — Vol Surface & Dealer Gamma Check
ThuMacro Cross-Check — Rates, DXY, Real Yields vs. Gold
FriWeek Close — Delivery Notices, Gamma Into Expiry, Next Week
Full Codex issues include the day’s primary map, invalidation levels, and what would change the read — written for speed, not for the long-form evidence bar the Ledger requires. Subscribers to The Quant Ledger receive the weekly title run and opening excerpt here; full Codex access is its own product.

Technical Analyst Market Report — GC anchor
Gamma Wall at $3,100 — Structure Into Friday Expiry
The weekly technical report anchors on <strong>GC</strong> and cross-checks MGC, XAU/USD, GLD, and GDXU for implementation. This week: price holding above the 2,980 value area with dealer net short gamma above <strong>$3,100</strong> — any sustained push into that zone accelerates mechanically unless vol expands enough to flip the book.
Session structure from Parallax: US overlap shows the cleanest CVD alignment; Asia gaps are flagged but not trusted for live bias until London confirms. Footprint absorption at 3,040–3,055 is the line between continuation and mean-reversion back to 2,980.

Full report includes TPO profile for the week, footprint levels, charm decay into Friday expiry, stacked imbalance zones, and explicit if-then execution framing — when to lean, when to wait, and what invalidates the structure. Nothing publishes without clearing the Sentinel evidence checklist attached to the same weekly briefing.

Market Codex
Market Codex is a separate product. It may pull from some of the same sources and share some of the same meaningful information, but the two are not coupled. The Quant Ledger is the multi-asset quant research publication and translation layer for the desk — gold-led, not gold-only. The Codex runs Sun–Fri as a free live Telegram signal room —join it here.
