The move is real and it is large relative to what came before it. WIG-BANKI's 2.93% session gain compares with a five-session change of just 0.44% since 29 September, which means most of the five-day gain happened in this single session. WIG20 rose 1.61% to 4,222.36 on the same day, WIG climbed 1.58% to 159,012.30, and mWIG40 added 1.82% to 10,713.47. sWIG80 lagged at 0.24%. Banks outran the broad market by roughly double, the same relationship this desk flagged on 1 October 2026, except in reverse: then WIG-BANKI fell nearly twice as fast as the index; now it rises nearly twice as fast.#
That symmetry matters for what the desk wrote on 2 October and again on 6 October. The 2 October note read the sector's sharper fall as banks re-examining the rate-cut assumption in their own valuations, with a flat złoty failing to corroborate a genuine Polish repricing. The 6 October morning note, filed after GUS lifted its 2025 growth estimate to 3.8%, argued that stronger growth strengthens the case for a Council hold, even as WIG-BANKI's continued underperformance against WIG20 still looked like a sector pricing cuts the growth data argued against. The session that followed does not settle either reading: a rally the size of this one is consistent with banks catching up to a hold the growth print favours, but it is just as consistent with a bounce in stocks that had simply fallen further and now look cheap against sector peers.#
The WIG-BANKI session cannot tell the desk, on its own, whether Warsaw's banks just repriced a rate decision or merely rebounded from being oversold.#
The valuation layer offers a partial check rather than a verdict. PKO Bank Polski trades at a price-to-earnings ratio of 14.2 and a price-to-book of 2.75 with a 5% dividend yield; Pekao trades cheaper, at 11.2 times earnings and 2.21 times book, with a 7.2% yield; PZU sits lowest of the three at 9.6 times earnings and 1.8 times book, yielding 6.7%. None of these multiples look stretched after a single strong session, which is consistent with a rotation into names the market had marked down on dividend yield grounds as much as with a genuine re-rating of the rate path. The currency leg, which the 2 October note treated as the independent check on a Polish-specific repricing, still is not confirming anything: EUR/PLN last traded at 4.3793, unchanged on the session and up just 0.29% over five sessions. A sector repricing a material change in the expected policy path would ordinarily be expected to show up somewhere in the złoty; so far it has not.#
That leaves the 2 October and 6 October morning readings only partially tested, not resolved, and the desk grades them as such rather than claiming vindication either way. The growth-versus-rates tension those notes identified is still live. What would resolve it is the decision itself, due at 10:00 UTC on 7 October 2026: a hold accompanied by language reaffirming the March 2026 projection's mid-2027 return-to-target framing would make this session's rally look like banks front-running a hold the growth data supported, consistent with the 6 October reading; a cut, or communication that signals openness to easing sooner despite the stronger growth print, would mean the prior readings on both the 2 October selloff and the 6 October underperformance were simply premature, and the rally itself becomes the piece that needs a fresh explanation.#
