WIG-BANKI's decline on 14 October, the day Poland's September CPI print breached the NBP's 3.5% upper tolerance band, shows the equity market is not pricing the overshoot as a trigger for near-term policy tightening.
- What would prove it wrong
- This reading is overturned if the 19 October employment and wages release or the 20 October industrial production print shows wage or output acceleration that, combined with the CPI overshoot, prompts explicit RPP commentary treating the inflation path as newly policy-relevant.
- Review condition
- the 20 October 2026 Poland industrial production & PPI release (GUS): a reading showing output accelerating above September's pace would weaken this view; a reading in line with or below September's trend would sustain it

- Retired · 19 October 2026
- How it settled
- WIG-BANKI rose 1.09% on 16 Oct and is up over the trailing 5 sessions, directly contradicting the original premise that the index's decline on 14 Oct signaled markets were not pricing the CPI overshoot as policy-relevant; with the 19 Oct employment/wages data now landed within the stated window, the falsifier condition has had its data point arrive, so the reading can no longer be treated as an untested, sustained stance.
A dated research thesis and its assessment. This is not portfolio performance or an investment recommendation.
