GUS: Inflation Rebounds in July, Driven by Fuel
Poland's Central Statistical Office (GUS) published its flash estimate of July inflation on 1 August 2026 — consumer prices rose 3.0% year-on-year, a marked acceleration from the previous month. The main driver was fuel prices, which jumped 15.8% y/y and 13.9% compared to June alone. By contrast, food and non-alcoholic beverage prices actually fell 0.4% y/y — a reminder of how unevenly price pressure is spread across the Polish economy right now. GUS will publish the full, detailed breakdown on 13 August, but the flash estimate alone was enough to unsettle financial markets.
Why does this particular reading matter so much? Because 3% sits clearly above the National Bank of Poland's (NBP) inflation target of 2.5% (with a tolerance band of +/-1 percentage point). Just days earlier, at the end of July, NBP Governor Adam Glapiński had signalled that another interest rate cut could come as soon as September 2026. The fresh inflation data now puts that scenario in serious doubt — with direct consequences for your wallet, whether you are saving or repaying a loan.
Why Rising Fuel Prices Complicate the Central Bank's Decision
When the Monetary Policy Council (RPP) sets interest rates, it looks not just at the headline inflation figure but at what is driving it. A near-14% monthly jump in fuel prices is a signal that cannot be brushed aside, even though it partly reflects external factors — global oil prices, the zloty's exchange rate, base effects from a year ago — rather than overheating domestic demand. The trouble with fuel prices is that their swings feed quickly into transport costs, which in turn filter through, with a lag, into the prices of almost everything else.
This puts the RPP in a difficult spot. On one hand, the current NBP reference rate stands at 3.75% — its lowest level since March 2022, following March's cut. Continuing the easing cycle would support borrowers and the broader economy. On the other hand, cutting rates just as inflation rises and drifts further from target risks looking like a policy mistake, and could delay a return to target in the coming quarters. Financial markets are already recalibrating expectations: a September cut, until recently treated as close to certain, is now just one of several possible outcomes.
What This Means for Your Money — Three Concrete Consequences
Deposits and savings accounts: real returns are shrinking, but still working in your favour
The real return on your savings is, put simply, the difference between the interest rate a bank offers and the inflation rate. With the NBP reference rate at 3.75%, banks can still offer deposit and savings account rates in the region of 4-5% annually, especially on promotional offers for new funds. With inflation at 3%, your savings are still gaining real value — but the margin is thinner than it was a few months ago, when inflation was lower.
This raises a practical question: what happens to deposit rates if the RPP does eventually cut rates, just later than September? The answer is straightforward — banks trim rates on new deposits and savings accounts almost immediately after an RPP decision, often pre-empting it based on guidance alone. If you want to lock in today's rate for longer, it is worth considering a longer-term fixed deposit now, before any eventual cut (even a delayed one) has a chance to pull bank offers down. You can check current fixed-deposit offers and compare them against flexible savings accounts, which do not require locking your money away for a set term.
Loans and mortgages: a September rate cut — and cheaper instalments — is no longer a sure thing
If you were counting on a September RPP decision to lower your variable-rate loan instalment, today's inflation reading is a warning sign. The reference indices underlying variable rates on personal loans and mortgages respond not only to actual RPP decisions but to market expectations about future moves. The less certain a September cut becomes, the more slowly those indices will fall — meaning your instalment could stay at its current level for longer than expected just a week ago.
For anyone still planning to take out a loan, this is a good moment not to delay a decision while waiting for a "sure" cut that may well be pushed back. Rather than wait, it makes sense to calmly compare current personal loan offers and check whether the terms available today already fit your creditworthiness. The same applies to mortgages — if you are weighing a fixed rate against a variable one, it is worth reviewing current mortgage offers to see which option better shields you from uncertainty over the pace of future rate cuts.
How to Make Financial Decisions in Such an Uncertain Moment
The key rule: do not plan your household budget around announcements — plan it around actual decisions. A governor's remark from a few days ago is still just a remark, not an RPP decision. History shows that central bank communication can shift from month to month as new data comes in — and today's inflation reading is exactly that kind of new piece of the puzzle.
- If you have spare cash and are considering a deposit, think about splitting it between a fixed-term deposit (to lock in today's rate) and a flexible savings account (for quick access if you need it).
- If you are planning to take out a loan, do not delay your decision purely on the expectation of a September cut that is no longer guaranteed. Compare what is available today and check whether it meets your needs regardless of the RPP's next move.
- If you already have a variable-rate loan, budget for a scenario where your instalment does not fall for a few more months, rather than assuming automatic relief starting in October.
What Comes Next — The Calendar for the Coming Weeks
The next key date is 13 August 2026, when GUS will publish the full, detailed inflation data for July, broken down by spending category. That data — not the flash estimate — will form the basis for the Monetary Policy Council's final assessment ahead of its September meeting. If the detailed figures confirm that the price rise is mostly fuel-driven and temporary, and that core inflation (excluding food and energy) remains under control, the odds of a September cut could partially recover. If price pressure turns out to be broader, though, the RPP may choose to pause its easing cycle for longer.
Summary — What You Should Do
July's 3% inflation reading is a reminder that the road back to the NBP's inflation target is rarely a straight line. For your wallet, this means: your savings are still gaining real value, but it is worth considering locking in today's rate for a longer term before any future rate cuts have a chance to erode it. For borrowers, reduced certainty about a September cut means financial decisions should be based on today's conditions, not promises. Before deciding anything, take a moment to compare current offers — whether fixed deposits, savings accounts, personal loans, or mortgages — and keep an eye on GUS's publication calendar and RPP statements so the next twist does not catch you off guard.
