Japan Government Bond (JGB) 30-Year Yield (Daily)

## What this measures

The 30-year yield on Japanese government bonds (JGBs), in percent per year, daily, as published by Japan's Ministry of Finance in its JGB interest rate table (constant-maturity yields by term).

## Why it matters

The 30-year JGB yield is where Japanese life insurers and pension funds buy. It is the part of the curve most exposed to Japan's debt load and to the Bank of Japan stepping back from buying bonds.

## How to read it

Higher means dearer government borrowing at that term. Yields rise when markets expect higher policy rates or inflation, or ask more to hold the debt. Compare with the series' own history, with the other tenors (the curve slope) and with the US Treasury yield of the same term.

## What it does not say

It is the MOF's constant-maturity reading from market quotations, so it can differ slightly from a single benchmark issue. Nominal, not inflation-adjusted. Days the market is closed have no point.
