Overview
- The study, titled “Keep calm and carry cash,” draws on the Greek debt crisis, the Covid‑19 pandemic, Russia’s 2022 invasion of Ukraine, and the April 2025 Iberian blackout.
- The guidance suggests about €70–100 per person to cover essentials for roughly three days, echoing advice already used in the Netherlands, Austria, and Finland.
- During Covid‑19, euro banknote issuance rose by more than €140 billion, issuance jumped about 36% in countries near Ukraine in 2022, and the Iberian blackout briefly made cash the only workable payment method for many.
- The ECB urges central banks, commercial banks, and authorities to strengthen cash supply chains, maintain strategic reserves, and ensure ATM networks can handle sudden surges.
- The recommendation is precautionary rather than a mandate and is presented alongside ongoing work on a potential digital euro as everyday cash use declines.
