While much scholarship has focused on how asymmetry accommodates minority regions and mitigates secessionist pressures, this study highlights the role of ‘standard regions’. Based on elite interviews in Andalusia, Extremadura, Murcia and the Valencian Community, contextualised with survey data, the findings indicate that asymmetry loses acceptance when it is seen as opaque, system-weakening or generating distributive grievances. Under these conditions, asymmetry risks fuelling renewed territorial tensions rather than fostering stability.
