The Curious Mind Research Letter

The Research Letter is deep, original investment research written by one person and read by a small list. Each issue takes a single structural question — the kind that decides returns over years, not weeks — and works it through properly: the history, the mechanics, the numbers, and what would prove the argument wrong.

Every issue is timestamped. The date and the relevant prices are printed in the piece, so the calls can be checked against the tape rather than against my memory of them. The archive is the argument.

The Record So Far

Research Letter No. 1 — The Ledger War.

Published August 7 2026, with gold at $4,377. The case that the machinery of wartime finance — the 1942 playbook, where the state supports the price of its own debt rather than pay the market’s rate — is reassembling itself piece by piece, in language too boring to notice.

Two weeks later, with the 30-year yield at a near two-decade high, the U.S. Treasury announced — off-cycle — that it was at least doubling its buybacks of long-dated bonds, citing “liquidity support.” Long yields fell immediately.
