The 23 September note set a specific test. EUR/PLN's rise to a 20-day high was read as mostly a dollar-strength effect, not a złoty-specific repricing, and the reading was to stand as long as EUR/PLN kept tracking USD/PLN and EUR/USD rather than diverging from them. The retirement condition was explicit: EUR/PLN weakening against the euro even as EUR/USD stabilised or reversed.#
That precise condition has not been met. EUR/USD has not stabilised or reversed since 23 September; it has continued falling, down 1.14% over five sessions and 2.2% over the month, and it printed a fresh 20-day low on 29 September. USD/PLN, meanwhile, is up 1.91% over five sessions and 3.12% over the month, comfortably the largest of the three moves. EUR/PLN's own five-session change is a much smaller 0.74%. The dollar leg is still doing the heavy lifting, exactly as the 23 September reading described, so this is not the retirement scenario. It is closer to confirmation, but the desk should be precise about what kind.#
A dollar falling against the euro while still gaining against the złoty is not evidence the złoty has decoupled from the dollar story; it is evidence the dollar story has simply rotated legs.#
The asymmetry matters for anyone hedging PLN exposure through EUR crosses. A book that hedges złoty risk by assuming EUR/PLN and EUR/USD move together is being tested here: EUR/USD's slide should, on that assumption, have dragged EUR/PLN lower too. Instead EUR/PLN is essentially flat on the session and only modestly higher over the month, 0.83%, while USD/PLN absorbs the dollar move directly. A hedge built on the EUR/PLN leg alone is currently under-protected against dollar weakness expressed through USD/PLN, because the two crosses are not moving in lockstep on 29 September.#
One item on the wires on 29 September complicates any purely fiscal read of PLN: a prime ministerial announcement on PIT threshold changes reportedly set for 2027. There is no bond, swap or fiscal-gap figure in the data that ties that announcement to 29 September's currency move, and the złoty's near-flat session against the euro gives no support for treating it as market-moving. The honest read is that the currency tape shows no fiscal signal on 29 September; whatever this policy story means for the deficit path is a separate question the FX market has not yet priced.#
The limitation here is real: a 20-day low in EUR/USD is one data point, not a trend reversal, and a single wire item calling the dollar's appreciation potential exhausted is one source's view, not a house call. What would genuinely test the 23 September reading is a session where EUR/USD stabilises or turns higher while EUR/PLN keeps rising against the euro; that would be the złoty repricing on its own terms rather than riding the dollar's coattails. That has not happened as of 29 September. The desk keeps watching the same three crosses together, not EUR/PLN in isolation.#
