The repricing wall

The rate a stock carries is its interest bill divided by the debt it is paid on. Both are published as shares of GDP, so GDP cancels and what is left is a rate. The market rate is the ECB's long-term convergence yield, a monthly average — the latest published is September 2026. It trails the screen by a few weeks, and when yields have moved since, the wall has moved with them. Committed is debt multiplied by the difference.

The denominator is the average stock across the interest year, not the latest one. Interest is a flow across a year and a debt ratio is a level at a date; dividing one by the other mixes two different objects, and the error is signed. At 2026-Q1 Romania's stock stood 2.30 points above its 2025 average and Greece's stood 6.70 points below, so the end-of-period stock flatters a country whose debt is rising and penalises one whose debt is falling — backwards along the very axis this ranks, and enough to swap the top two places.

This is not a forecast of rates, a default probability, or a rating opinion. A government can refinance more cheaply if yields fall, lengthen its maturity profile, or run a surplus. The wall is what the arithmetic commits to if none of that happens — the baseline every one of those choices is measured against.
