Questions about the South Korea score

What does a score of 61.0 mean for South Korea?

61.0/100, band 50–65: some of the discipline holds and some of it slips, which is what the middle looks like. That is 11.0 points above the 50 mid-point of the scale. Seven weighted dimensions produce the figure and no analyst adjusts it afterwards. Nothing in it is a forecast — it grades what South Korea's central bank has already done, said and delivered.

How often is South Korea's score updated?

Nightly, off that day's public releases; this page carries the 2026-09-08 run. There is no reading from seven days ago to set this one against. A 90-day trailing average damps single prints, so a weekly move past a couple of points is a real one. Tomorrow's run replaces the 2026-09-08 figure outright rather than revising it in place.

What is the 50–65 credibility band?

Five bands cut the scale — ≥ 80, 65–80, 50–65, 35–50, < 35 — and 50–65 is step 3. South Korea clears its 50 floor by 11.0 and stops 4.0 short of 65. The step above is 65–80 and the step below is 35–50. Bands grade monetary behaviour, not default risk, so none of this is a credit rating.
