In 2011, he set up Greenmantle LLC, an advisory business specializing in macroeconomics and geopolitics.
Ferguson's television series The Ascent of Money won the 2009 International Emmy award for Best Documentary. In 2011 his film company Chimerica Media released its first feature-length documentary, Kissinger, which won the New York Film Festival's prize for Best Documentary.
Published in 2011, Civilization: The West and the Rest examines what Ferguson calls the most "interesting question" of our day: "Why, beginning around 1500, did a few small polities on the western end of the Eurasian landmass come to dominate the rest of the world?"
Ferguson sometimes champions counterfactual history, also known as "speculative" or "hypothetical" history, and edited a collection of essays, titled Virtual History: Alternatives and Counterfactuals (1997), exploring the subject. Ferguson likes to imagine alternative outcomes as a way of stressing the contingent aspects of history. For Ferguson, great forces don't make history; individuals do, and nothing is predetermined. Thus, for Ferguson, there are no paths in history that will determine how things will work out. The world is neither progressing nor regressing; only the actions of individuals determine whether we will live in a better or worse world. His championing of the method has been controversial within the field. In a 2011 review of Ferguson's book Civilization: The West and the Rest, Noel Malcolm (Senior Research Fellow in History at All Souls College at Oxford University) stated that: "Students may find this an intriguing introduction to a wide range of human history; but they will get an odd idea of how historical argument is to be conducted, if they learn it from this book."
Historians and commentators have considered his views on this issue and expressed their critical evaluation in various terms, from "audacious" yet "wrong", "informative", "ambitious" and "troubling", to "false and dangerous" apologia.. Richard Drayton, Rhodes Professor of Imperial History at King's College London, has stated that it was correct of Seumas Milne to associate "Ferguson with an attempt to "rehabilitate empire" in the service of contemporary great power interests". In November 2011 Pankaj Mishra reviewed Civilisation: The West and the Rest unfavourably in the London Review of Books. Ferguson demanded an apology and threatened to sue Mishra on charges of libel due to allegations of racism.
In 2011, Ferguson predicted that Grexit (the notion of Greece leaving the Euro currency) was unlikely to happen, but that Britain would leave the European Union in the near future as it would be easier for Britain to leave the EU owing to the fact it was not part of the Eurozone and that returning to a national currency would be harder for countries who had signed up to a single currency. In 2012, he described the Eurozone as a "disaster waiting to happen."
