Podcast 145: Digital euro is not crypto. It is digital cash, with Rainer Olt

For more than a decade, payments innovation has been defined by convenience. Faster checkouts. Invisible wallets. Seamless cross-border flows. The market rewarded whoever reduced friction the most.

This episode of the Fintech Garden Podcast shifts the lens. In a conversation with Rainer Olt, Head of Payments and Settlement Systems at Eesti Pank, the focus moves from speed to sovereignty. The digital euro is not introduced as a product upgrade. It is presented as infrastructure designed for continuity.

The discussion reframes what progress in payments actually means.

Efficiency Built the System. Dependency Exposed It.

Europe’s retail payments ecosystem works smoothly under normal conditions. Global card schemes dominate in-store transactions. Big Tech wallets lead online and mobile payments. The experience is optimized.

But concentration creates vulnerability.

Many euro area countries rely almost entirely on non-European card networks. A significant portion of digital payments flows through external providers. If those rails fail, the disruption is immediate and systemic.

The digital euro responds to that exposure. Its purpose is to establish a sovereign payment rail that ensures Europe can continue processing transactions even during technical failures, cyber incidents, or geopolitical stress.

Payments are not just a service layer. They are economic infrastructure.

Digital Euro Is Digital Cash, Not Crypto

A recurring misconception addressed in the episode is whether the digital euro is a cryptocurrency or blockchain token.

It is neither.

The digital euro would be central bank money in digital form. A direct claim on the central bank, similar to physical cash. It is not a speculative asset and not privately issued. Stability, not volatility, defines its purpose.

This distinction is structural. Stablecoins depend on private reserve management. Commercial bank money depends on institutional solvency. The digital euro, like cash, represents sovereign money.

The design objective is to replicate the core characteristics of cash in a digital environment.

Offline Payments as the True Innovation

The most technically ambitious feature discussed is offline functionality.

Today’s digital payments require connectivity. Even offline card payments introduce credit risk because balances are verified later. The digital euro aims to enable peer-to-peer and merchant payments without internet access, with value stored securely on devices and synchronized once connectivity returns.

In practice, this creates a hybrid model. Digital value that behaves like physical cash.

This reduces systemic credit exposure and ensures payment continuity during outages. It also introduces trade-offs. If funds are stored locally and a device is lost, recovery may not be guaranteed.

Resilience requires design compromises.

Public Rails, Private Innovation

The episode also addresses concerns that the digital euro might compete with European payment initiatives.

The argument presented is the opposite. A public payment rail that connects all merchants across the euro area could reduce infrastructure costs and enable private European providers to build competitive front-end solutions on top.

Rather than replacing banks or fintechs, the digital euro provides a common backbone.

Public infrastructure does not eliminate competition. It reshapes it.

Built for Crisis, Validated by Daily Use

A core takeaway from the conversation is that resilience cannot be theoretical. A payment system designed for emergencies must be used daily to function when needed.

Legislation is still under negotiation, and pilot programs are expected before potential issuance around 2029. Holding limits are likely to prevent destabilizing flows from bank deposits into digital euro balances during periods of stress.

The objective is not to replace existing rails, but to introduce redundancy.

Speed defined the last phase of payments innovation.

Resilience may define the next one.
