We investigate the dramatic 2008-2009 trade collapse using microdata from a small open economy, Belgium. Belgian trade essentially fell because of reduced quantities and unit prices, rather than fewer firms involved in international transactions, fewer trading partners per firm, or fewer products traded. Our difference-in-difference results point to a fall in the demand or tradables – especially durables and capital goods – as the main driver of the recent collapse. Finance and involvement in global value chains player only minor roles. Firm-level exports-to-turnover and imports-to-intermediates – as well as exports-to-production and imports-to-production – ratios reveal a comparable collapse of domestic and cross-border operations. Access to credit affected both types of activities to the same extent. Overall, our results point to a general fall in demand and not a crisis of Belgian cross-border trade per se.
