Curated insights and technical field notes on Liquidity.

Current note

Instant rails broke the treasury day

The newest published argument and its visual artifact lead the page.

Editorial posture

The first note sets the editorial contract: one dated argument, explicit tradeoffs, and visual proof close to the section it explains. More lanes appear when enough published work gives them substance.

Decision frame

Recommendation, rejected paths, and the operating proof behind the call.

Visual proof

Diagrams and original artifacts stay near the argument they explain.

Source posture

Public claims stay tied to released work or cited material.

Payments

Instant rails broke the treasury day

ACH cleared overnight, wires ran on business hours, and float was predictable. FedNow and RTP ended that. With 42 percent of RTP payments landing nights, weekends, and holidays, treasury teams are positioning cash by the hour - and the Fed discount window still keeps bankers' hours.

Lead essay

The current Doric argument leads the index ahead of the chronological archive.

The archive starts narrow by design. New Field Notes enter only when they meet the same proof, source, and visual-artifact bar.
