What would prove it wrong
This reading is overturned on the rate-path leg if the Poland CPI final print on 15 October 2026 shows inflation accelerating away from the March NBP projection's path; it says nothing about the fiscal leg, which would instead need evidence such as weak POLGB auction demand or explicit RPP commentary tying the deficit to policy risk.
Review condition
the Poland CPI final print (GUS) on 15 October 2026: a reading that decelerates back toward the March NBP projection's path supports the rate-path premise; a print that accelerates away from it would unwind that specific leg

How it settled
The 4.1% CPI print breaching the 3.5% NBP upper band constitutes inflation accelerating away from the projected path, which is precisely the stated falsifier condition for the rate-path leg; the break-condition fired as specified, so the reading must be retired rather than sustained via rationalization.
