During her 2015 campaign, Barcelona's mayor Ada Colau promoted the idea of launching a local currency in her city. Colau viewed a local currency as a way of defending independent businesses and residents from rapidly-rising rents and benefits that are disproportionately reaped by corporate chains instead of local stores. Though the community currency failed to materialize in Barcelona, the city immediately to its northeast, Santa Coloma de Gramanet, created a local currency this year.
