— 1 · The Locked Call

Türkiye's October 2026 annual CPI lands ≤40% — P = 0.93.

We lock a binary: Türkiye's annual consumer price inflation rate for October 2026 prints at or below 40%, per TÜİK. Confidence 93%.

— 2 · Why it's nail-able

Disinflation is slow but consistent, and the ceiling allows eight points of reversal.

Turkish annual inflation eased to 31.75% in July from 32.11% in June, continuing a grinding disinflation from far higher levels, with monthly prints running near 1.8%. Reaching 40% within three months would require monthly inflation to roughly double and sustain. Our ceiling allows about eight points of reversal. Confidence 93%, and not higher, because Türkiye is the most policy-sensitive inflation series we lock: a lira slide or an abrupt shift in monetary stance has repeatedly reset this number, and administered price adjustments land in lumps. Scored on the official TÜİK headline annual CPI — we note that independent estimates of Turkish inflation run materially higher, and the official series is the published criterion.
