Treasury Yields

Overview

Treasury Yields sources daily constant-maturity market yields from the Federal Reserve (FRED), the same rates used to construct the Treasury yield curve. Nominal yields span 1-month to 30-year maturities and TIPS real yields span 5-year to 30-year. Historical month-end snapshots go back to January 2010. Paid plans also get the standard curve spreads (10yr-2yr, 10yr-3mo, 30yr-5yr, 5yr-2yr), inversion flags, the curve's shape, and breakeven inflation at each TIPS maturity (the nominal yield minus the real yield, the market's implied inflation rate).

Formula

One function covers the whole catalog: the first argument names the source, the next are its inputs, and the field after them says which single value lands in the cell. Formulas covers the grammar that applies to all of them.

=VERVE("treasuryyields", "bills")

=VERVE.CALL("treasuryyields", "bills")

Inputs

Required inputs are positional, in the order below, followed by the field. Everything else is passed as a "name", value pair after that — the same shape as SUMIFS. Premium inputs are accepted on every plan but only take effect on plans that include them.

Passing an option

=VERVE("treasuryyields", "bills", "date", "2025-06")

=VERVE.CALL("treasuryyields", "bills", "date", "2025-06")

What lands in your sheet

The field — the argument after the inputs — is what makes the formula resolve to one cell. Its value is a dot-path from the table below, so swapping it is how you pull a different value — one formula per column.

Seeing everything at once

Leave the field out and the formula returns the whole response instead: two columns, field name on the left and value on the right, spilling from the cell you typed in.

=VERVE("treasuryyields")

=VERVE.CALL("treasuryyields")

Response fields

Paths are relative to data. Each one is exactly what the field argument accepts, so swapping it is how you pull a different value into a cell. On a plan without a Premium field the cell reads #PREMIUM(field) rather than a value, so a locked field never looks like a real answer.

When a cell doesn't fill

A failed lookup returns readable text starting with #ERR rather than a spreadsheet error, because Excel cannot show a custom message on a real error — you would get a bare #VALUE! with no reason. The trade-off is that IFERROR() will not catch it; test with LEFT(cell, 4) = "#ERR" instead. Error handling covers the rest.

Before the formula works

The add-in reads the API key you saved once in the side panel — the key never goes in the formula, so a shared sheet does not leak it and a collaborator without access simply sees the last calculated values.

1. Install the add-in for Google Sheets or Excel.
2. Open the side panel and sign in, or paste a key from your dashboard.
3. Type the formula above into any cell.
