Ermua’s economy has historically been rooted in agriculture and local crafts, but over the years, it has diversified to include industrial manufacturing, particularly in the metalworking sector. Small and medium-sized enterprises form the backbone of the town’s economy, contributing to its reputation as a hardworking and industrious community. The city’s strategic location near larger industrial hubs such as Bilbao has also enabled it to benefit from regional economic growth.
While not primarily a tourist town, Ermua’s local economy does enjoy a boost from visitors, especially during the festival season. Tourism-related services, such as hospitality, retail, and food, play a role in supporting the local economy, particularly in summer months when tourists and event attendees flock to the town.
Ermua’s artisans are well-known for their craftsmanship, with some local businesses specializing in handcrafted goods that reflect the region’s cultural heritage. Additionally, the Basque Country’s emphasis on innovation has led to a growing interest in technology and sustainable industry within the town, with modern business parks supporting these sectors.
