When I first arrived in Spain, the banking system felt quite traditional. I was surprised to discover that they are not lagging in technological innovation at all, especially in the blockchain arena, where they’ve been making significant moves.
I was chatting with a friend about this over the weekend and decided to dig into what some of the major banks are doing. It turns out CaixaBank and Santander are leading the pack. They’ve moved beyond the ‘research’ phase and are actively implementing blockchain technology in their operations. For instance, CaixaBank is participating in the European Payments Council’s digital euro prototype testing, exploring how blockchain can handle our future daily payments. Santander started even earlier, issuing a bond on the blockchain several years ago, which greatly simplified the process and boosted efficiency. It seems these seemingly ‘old-school’ banks are actually tech wizards behind the scenes.
What Are the Banks Working On?
In short, they are primarily exploring a few key areas:
Cross-Border Payments and Trade Finance
Traditional international transfers are slow, expensive, and involve too many intermediaries. Blockchain enables fast, peer-to-peer settlement. Santander’s former One Pay FX service was an early example. For anyone involved in international trade, this is a game-changer, saving a lot of time and fees.
Securities and Asset Digitalization
This involves ‘moving’ traditional financial assets like stocks and bonds onto the blockchain, turning them into what are known as ‘security tokens.’ The benefits include more transparent and efficient trading. BBVA has already facilitated corporate loans on the blockchain, making the entire process days faster than traditional methods.

Digital Identity and Customer Verification
Every time you open an account or do business at a bank, you have to bring a stack of identification documents for repeated verification, which is quite a hassle. Blockchain’s immutable nature makes it perfect for digital identity. In the future, a single encrypted digital identity might be all you need to conduct business quickly at any bank, thanks to blockchain in Spanish banking, eliminating the worry of forgetting documents. The collaborative Dalion project, involving several banks, is a great initiative in this direction.
To make it easier to understand, I’ve created a simple comparison table to show the changes blockchain technology can bring:
| Traditional Banking Process | Blockchain-Based Solution |
| International wire transfers | Near real-time settlement |
| Paper contracts & manual review | Automated execution via smart contracts |
| Repeated submission of ID | One-time digital identity verification |
| Opaque transactions, many intermediaries | Traceable transactions, disintermediation |
These technologies are still in their early stages and a bit distant from our daily lives. For example, it’s still uncertain when the digital euro will be widely available. Regulation is also a major challenge because, in finance, security and stability are always the top priority. Nevertheless, seeing these positive developments is exciting.
