ING Bank Śląski is leaning harder into Poland’s savings battle, extending its flagship deposit promotion and keeping a headline 5.50% annual rate on up to 400,000 zł for another month.
ING Bank Śląski extends 5.50% savings offer
That matters because the offer is not just a marketing gimmick: it is a direct bid to lock in sticky retail balances at a time when banks are competing more aggressively for household cash. For investors, the key question is whether these promotions are a manageable customer-acquisition cost or the start of a broader margin squeeze if banks have to keep paying up to defend deposits.

Under the new terms, ING’s Otwarte Konto Oszczędnościowe offers 5.50% for three months, provided customers open or already hold a current account, log in to the mobile app at least three times and make at least 15 card or BLIK transactions. The promotion, which began Sept. 17, now runs through Oct. 14, giving the bank extra time to convert rate seekers into active clients.
The scale is notable. ING is offering the top rate on as much as 400,000 zł, a ceiling that is unusually high for a retail savings campaign and makes the product especially attractive to affluent households parking larger sums. For existing clients bringing in fresh money from outside banks, the lender is offering 4.50% on up to 300,000 zł, also for three months, under nearly identical activity requirements.
The structure tells the story of the bank’s strategy: use deposits as an entry point, then monetize engagement through checking accounts, card usage and app adoption. That is a classic universal-banking play, and one investors should watch closely because it can support fee income and customer retention even if it puts pressure on near-term funding costs.
ING’s shares have held up well in recent trading, but the stock is already reflecting a strong run, leaving less room for the market to ignore deposit competition if it starts to spread across the sector. Deutsche Bank’s stock has also been firm, underscoring how investors are still willing to pay for European banks with durable earnings power, but retail funding pressure remains one of the clearest risks to that thesis.
The bigger narrative is that banks are being forced to defend cheap funding with more expensive, more targeted offers as savers become more mobile and more rate-sensitive. If this pattern persists into the autumn, the winners will be banks that can turn promotional deposits into broader customer relationships; the losers will be lenders relying on inertia and low-beta deposit bases.
For investors, the takeaway is straightforward: the deposit war is not a side story. It is a test of pricing power, customer loyalty and funding discipline — and ING is showing that the fight for household cash is still very much on.
