What forced the Spain to adopt the laissez faire policy?

Spain adopted the laissez-faire policy in the late 18th and early 19th centuries primarily due to the pressures of economic modernization and the influence of Enlightenment ideas promoting free trade and limited government intervention. The need to stimulate economic growth and increase competitiveness in the face of rising industrial powers led to reforms that reduced state control over the economy. Additionally, the failures of mercantilist policies highlighted the inefficiencies of heavy regulation, prompting a shift towards a more liberal economic approach.
