Stories the budget tells
Four arcs on the Office of Personnel Management's money, each assembled from public records. Every figure renders live from the same extracts the rest of the monitor uses, and every claim links its receipt.
Arc 01 · mandatory × discretionary
The budget that is mostly benefits
Quote “the OPM budget” and you have to say which one. The number that dominates is not a program at all — it is the federal retirement system.
The trust-fund outlays are benefits OPM disburses on behalf of employees and annuitants — not a thing OPM chooses to fund. At FY2027 they are roughly …× the entire discretionary operating budget, which is only about …% of all OPM budget authority. Folding them into “the budget” is how a ~$375 million operating budget disappears inside a ~$140 billion agency.
The full separation, drawn to scale, is on the overview.
Arc 02 · audit × traceability
Clean books, on records that are still paper
OPM runs some of the largest trust funds the U.S. government holds, and on the dollars its books are clean.
An independent auditor has issued a clean opinion on OPM's trust-fund statements for decades — covering the Retirement, Health Benefits, and Life Insurance program statements. Yet GAO has documented for more than two decades that the retirement processing behind those books is still largely paper-based and manually intensive, with repeatedly failed IT modernizations.
Same agency, two layers. The dollars reconcile because they are recorded and reconciled; the case files lag because they are paper, not data. Where information traces from a recorded transaction back to its source, even funds this large audit clean; where the records are manual, processing stays slow no matter how clean the ledger. That is precisely what an end-to-end data model would close. The full record is on the audit page.
Arc 03 · USAspending × the topline
Hundreds of billions obligated, almost none of it bought
In FY… OPM obligated … across the whole agency (USAspending toptier 024) — but most of that is annuity, health, and life-insurance benefit payments, not procurement.
Unlike the Department of War, OPM publishes award detail without a 90-day OPSEC delay, so the feed trails only by normal USAspending reporting lag. The full feed is on the spending page.
Arc 04 · OMB Historical Tables
A line that is the cost of the retirement system
OPM's budget-authority arc since the 1970s is not really an operating-budget story — it is a benefits story. Because the trust funds dominate, the line tracks the federal retiree population, health-benefit costs, and funding mechanics, not policy choices about OPM's own programs.
Which is exactly why the spine keeps this agency-wide budget authority separate from the discretionary operating budget — the operating side is a small, deliberate number this line would otherwise swallow. The series is nominal: OMB's Table 5.2 publishes no constant-dollar basis, and we do not synthesize one.
