Summary of 2025. Negative market surprises
— The scale of uncertainty and volatility generated by American politics — this is one of the four main negative surprises mentioned by Michał Szymański. He specifies that he means, among others: customs war and war in Ukraine.
The US tariff policy had an impact on the increase in inflation through, among others, increasing costs in supply chains. Experts indicate that it will slow down overall GDP growth. UN forecasts also warned that the global trade war could prevent the creation of up to 7 million jobs in the world.
The president of VIG/C-QUADRAT TFI also draws attention to the Polish debt market and what has happened there in the last 12 months. — The yield on Polish 10-year treasury bonds (the long end of the interest rate curve) remains above 5%. despite the sharp decline in interest rates and inflation — this is another negative surprise indicated by the expert.

For the state, the lower the yield on 10-year bonds, the better, because it means a lower cost of servicing public debt. Yield, simply put, is the interest rate the government has to pay investors on borrowed money, so when it falls, the budget spends less on interest. The state benefits directly from this, saving billions of zlotys which, instead of going to lenders' pockets, can be used for other expenses, such as investments or public services. Additionally, low profitability proves investors' high confidence in the Polish economy and the country's financial stability, which attracts foreign capital.
“With a few exceptions, no net purchases into equity funds despite a spectacular boom on both domestic and foreign stock markets” – this is another surprise mentioned by our interlocutor.
In addition, he adds “dollar weakness despite the global AI boom dominated by American companies“. Over the following months of 2025, the value of the dollar in the Polish currency decreased. In January, it even reached PLN 4.15, and from March it permanently dropped below PLN 4. The last few months have seen exchange rate fluctuations in the range of PLN 3.60-3.70. Currently, it is closer to the lower limit.
Market surprises in 2025. Lesson for the future
The year 2025 showed that financial markets can also reward those who think independently of the dominant narratives. The Polish stock exchange without a more important AI component or falling rates amid solid economic growth have shown how unpredictable the financial market is. If this year has taught us anything, it is humility towards simple stories and openness to the fact that market reality is almost always more complex than it may seem at first glance.
