The text reports selected findings from World Protest 2006-2013 to show that the crisis of 2007-2008 generated an intense wave of protests and, in poorer countries, also riots. Most often protesters demanded "real" democracy and called for anti-austerity measures. They also fairly often had the IMF as their main protest target. The text criticizes social movement research for taking insufficient interest in creditor-debtor struggles, and thus missing the factors that generate protests. It then turns to Occupy Wall Street (OWS) and the Association for the Taxation and Financial Transactions for the Aid of Citizens (ATTAC) to show how their working groups and initiatives challenge financial capital. The text pinpoints that ATTAC and OWS share in common that they defy financial capital both relying on expertise and on popularizing anti-finance discourses. Taking up anti-G20 protests in London in 2009, and Jubilee and Jubilee South transnational anti-government debt campaigns, paves the way for the argument that social movements (have to) combine focused anti-finance expertise, popular discourses and open protest to challenge the rule of financial capital. Conclusion calls for a Weberian, creditor-debtor-focused, perspective on social mobilization.
