The European financial sector is experiencing an unprecedented crisis of assurance in its own safety systems. The largest banking institutions in the continent have spent to their customers alarming recommendations on the request to collect physical cash at home. This is simply a dramatic change in communication, due to the fact that even late banks have aggressively promoted a complete departure from cash for digital payments. Why is this phrase so important? It is about an expected wave of cyber attacks that can completely paralyze electronic financial infrastructure in the coming months of 2025.
This unexpected advice demonstrates the scale of cybersecurity threats that modern banking must now face. There is simply a real hazard that millions of Europeans, including Poles, can be cut off from their savings without the anticipation of carrying out basic financial transactions. It's not a hypothetical script anymore, but a real threat that requires immediate response from each of us. The preparation of a tiny cash reserve may be crucial to maintaining financial liquidity in the face of a possible crisis.
Why are the banks on alert? A increasing Cyber Threat
The reasons for this extremist change in the approach of European banks to financial safety are profoundly worrying. They are not about hypothetical threats to the future, but about real and intensified cyber attacks. They are conducted by advanced hacker groups, frequently acting on behalf of state intelligence agencies. They have unlimited financial and technological resources to penetrate the world's most protected information systems.
Dutch banking professionals, who were the first to publically admit the weaknesses of their cyber protection systems, urge to each household the maintenance of a cash reserve oscillating between 200 and 500 euro. In Polish economical realities this translates into an amount about a 1000 zlotys. According to the calculations, this sum should be adequate for the average citizen to cover the most crucial life expenses for at least 1 week erstwhile all electronic banking systems cease to function. This is simply a fundamental change in banking philosophy, which over the last 2 decades has systematically sought to completely destruct cash from everyday financial circulation.
Statistics that frost blood in the veins. Three-fold increase in attacks
Statistics on the emergence in cyber threats in the financial sector are indeed alarming. European banks reported only in the first 4th of 2025 three times the number of incidents related to attempts to breach the safety of their IT systems in comparison to the same period of the erstwhile year. This indicates a systematic and planned run to destabilise the European financial infrastructure.
Most of these attacks are characterised by unprecedented method complexity. They usage a combination of different penetration methods, including artificial intelligence, advanced algorithms and software gapswhich the bank strategy developers may not really know about. The consequences of a successful cyber attack on European banking infrastructure could be disastrous not only for the financial institutions themselves but, above all, for millions of average citizens. Paralysis of electronic banking systems would mean the impossibility of making transfers, blocking access to mobile applications, shutting down ATMs and completely immobilising card payments. In practice, this could lead to halting the average functioning of the full economy And make social panic on an unprecedented scale.
Estonian script: What awaits Poles?
The script of the temporary collapse of banking systems has ceased to be a theoretical anticipation and has become a real threat. This is best illustrated by the example of Estonia, where in 2022 a massive DDoS attack against the country's major financial institutions caused nearly forty-eight hours of paralysis electronic banking and non-cash payments. Citizens were forced to return to cash transactions and to long queues in front of bank branches. This incident, although yet mastered without lasting harm to the Estonian economy, showed how susceptible modern financial systems are to cyber attacks and how rapidly all payment infrastructure based solely on digital technologies can collapse.
The European Central Bank and the national financial supervisors in the associate States have started intensive work on strengthening the resilience of the banking sector to cyber attacks. They make fresh safety protocols, emergency procedures and backup systems to minimise the effects of possible cyber incidents. This includes not only technological modernisation but besides staff training, global cooperation on the exchange of information on threats and coordination of defence activities between different countries and financial institutions.
How to prepare? Recommendations and actions of banks
The reactions of bank customers to informing messages vary widely. They reflect deep social divisions in assurance in financial institutions and the perception of cyber threats. any citizens see banking warnings as a sign of work and concern for client safety, while others are afraid that specified communications can make unnecessary panic leading to the mass withdrawal of cash from banks and to destabilise the full financial system. These fears are not unfounded, as past knows examples of a situation erstwhile even groundless rumors of bank problems led to run into banks and to real financial crises.
The banks effort to calm their customers, stressing that the recommendations for cash collection does not imply a deficiency of assurance in the stableness of the financial system. They are only part of sound hazard management and preparation for possible short-term disruptions to access to electronic services. Financial institutions have repeatedly stressed that they do not encourage the full withdrawal of savings from banks, but only to safe a tiny part of the funds in the form of physical cash that could cover the most crucial expenses in an emergency. It is worth listening to these suggestions and securing your regular functioning.
