The September flash CPI print at 4.0% narrows the Council's room to treat the post-fuel-cap inflation overshoot as transitory, even as WIG-BANKI valuations and a flat złoty still price a continuing NBP easing cycle.
- What would prove it wrong
- This reading is retired if the 7 October 2026 NBP rate decision or its communication signals a shift away from the mid-2027 return-to-target framing established in the March projection; it is sustained if the Council reaffirms that longer-term path despite the 4.0% print.
- Review condition
- the NBP rate decision (RPP meeting) on 7 October 2026: the Council's communication on whether the CPI overshoot prompts a shift away from the March projection's mid-2027 return-to-target framing
- Status
- Retired · 2 October 2026
- How it settled
- The referee is correct: the falsifier condition explicitly hinges on the 7 October NBP decision, which has not yet occurred, so there is no basis to claim the reading is 'sustained'; grading it as surviving before the triggering event happens is a flawed application of evidence, and the EUR/PLN vs USD/PLN dynamics cited belong to a separate 23 September reading's falsifier, not this one.
A dated research thesis and its assessment. This is not portfolio performance or an investment recommendation.
