Winner – Best Financial Services Loyalty Programme or Initiative
yellow, is a bank-wide loyalty program created for Small Businesses and professional people in Greece. It has been credited with making Piraeus Bank the leading loyalty bank in Greece and making it a “loved brand”. No mean achievement for a financial institution.

Piraeus Bank first launched its loyalty program in 2016, as a customer-oriented bank-wide initiative, but it rose to the challenge specifically to meet the needs of both small businesses and professionals with the launch of “yellow business” in 2020.
The figures are impressive. At the time of entering the International Loyalty Awards 2022, it had grown its membership base to more than 2.3 million and had enriched the product value proposition. At the same time, the program remained profitable for the Bank, and was credited with growing the Merchants’ network by 45%.
At the same time, yellow accelerated long-term goals faster than expected in order to benefit what Piraeus describes as the “wounded” backbone of the Greek Economy and created the “yellow business” which was the new pioneer scheme of daily reward for Small Businesses and Professionals.
Among the achievements during this two year period were digitisation of the programme so that yellow rewards could be earned and redeemed online, which was particularly important during covid lockdowns. This was followed quite quickly in 2021 with the yellow app.
Gains were significant and quickly felt. The Piraeus Bank organisation increased its market share of the Banking Loyalty industry to 49%.
This was the result of a sustained and well planned marketing program which included:
- 22 Above the Line corporate campaigns
- A significant number (confidential) of both Above and Below the Line campaigns
- A significant number (confidential) of Partners’ promotional campaigns
- More than 874 Facebook and 498 Instagram posts that emphasized yellow social media presence.
Yellow member benefits

Members enjoy exclusive offers and earn/ redeem yellows with business cards, loans and other business products & transactions such as e-banking payments.
A key element, which provided the yellow business with a competitive advantage, was the launch of “Shop in the Neighborhood”. It aims to provide incentives for consumers to choose small local businesses for their purchases, so that these retailers boost their sales and turnover. Yellow business provides the mechanism in order for the customers to be able to redeem yellows at the retailers’ POS.
Mission
yellow was tasked with one double mission: to create positive customer experiences for its members by rewarding most of their daily transactions and increasing cross-sell and rewarding behaviors. By so doing, it would increase “profitable loyalty” to the Piraeus Bank Organization.
Members enjoy exclusive offers and earn/ redeem yellows with business cards, loans and other business products & transactions such as e-banking payments.
