A dated, versioned record of the starting rates we publish for aircraft financing, alongside the macro interest-rate environment at the time.
The FLYING Finance Aircraft Loan Rate Index is a dated, versioned record of the starting rates we publish for aircraft financing, alongside the macro interest-rate environment at the time. Each entry in the Index is a numbered, dated “reading” — a snapshot you can look back on, compare over time, and cite. This page explains how the Index is built. The readings themselves live on the Historical Archive.
FLYING Finance has always published starting rates for the aircraft categories we finance on our Current Rates page. The Rate Index takes that same published data and adds a timestamp: on a weekly cadence, we log the currently-posted starting rate for each category, plus the live macro benchmark rates it sits alongside, as one numbered reading in a permanent, publicly viewable archive. It is a packaging and presentation layer on data we already publish — not a new or different rate.
Every reading captures two things as of that date:
A new reading is logged automatically on a weekly cycle. The Index never backdates or fabricates history: it started with Reading #1 on September 21, 2026, and each subsequent reading is added going forward, dated the day it was actually captured. At most one reading is kept per calendar day, so the archive stays a clean, chronological record rather than a noisy log.
The Rate Index is a historical record, not a pricing formula. The starting rate for each aircraft category reflects underwriting tier, aircraft type and age, loan structure, and the borrower’s credit profile — it is not mechanically derived from the benchmark rates shown alongside it. Those benchmarks are included for context and transparency, so you can see the broader rate environment each reading was captured in, not as an input to a public calculation.
