Transaction Growth & Acceleration of Development

The evolution of transaction volumes processed through the DIAS Payment System reflects a steady growth trajectory, which has significantly strengthened and accelerated over the past five years.

During the period 2015–2020, transaction volumes grew at an average annual rate (CAGR) of 7%, reflecting the gradual expansion of interbank payments and the systematic enhancement of the System’s core services.
In the period 2020–2025, growth accelerated substantially, reaching an average annual rate (CAGR) of 13%, driven by the evolution and scaling of DIAS’ infrastructures and services, the transition towards digital and instant payments, and the broader adoption of its services by banks, businesses and consumers.

This divergence clearly demonstrates that recent growth momentum is not merely a natural market evolution, but is directly linked to the active role of DIAS in shaping a modern and efficient payments environment.
