The rise and fall of governments, democracies, and tyrannies are all too often at the mercy of the ebb and flow of plain, hard cash. Currencies today are very much the defining feature of nations, individually and collectively. A flailing and fragmented Europe seeks to hang together—retain its global reach—on the strength of a single currency that has taken on a life or near-death of its own, its very existence becoming an end in itself. Across Africa and Asia, the Americas north and south, continents and peoples are all too often held hostage by forces unleashed in the name of money. It is this kaleidoscope of silver, gold, and paper, often in the magnitude of tsunamis, that we set out to explore in the Summer issue of World Policy Journal.We begin with The Big Question, a selection of global thinkers reflecting on how much confidence each has in his or her nation’s banking system—the fundamental conduit of value within countries and across borders.

From Argentina, Meredith Hoffman explores the perils of a currency that goes off the rails, while in Beijing, Donald Straszheim looks at the strength of what may be the world’s next global reserve currency—the renminbi. Finally, for our Conversation, we turn to London, where Xavier Rolet, a French banker who has taken the reins of the London Stock Exchange Group, seeks to bring intelligence and rationality to the jungle of trading money.In our Portfolio, photographer Ahmed Deeb and writer Max Siegbelbaum go underground in Gaza to profile a 12-year-old Palestinian and the illicit tunnels he and his mates are burrowing between Gaza and Egypt—circumventing the Israeli embargo to bring contraband to their countrymen. The Century Foundation’s Michael Wahid Hanna warns of the toxic confluence of religion and politics in fragile, contemporary Egypt. In Burundi, Rosalie Hughes is on hand for the arrival of Philippe Starck’s Idea Box, that holds new hope and promise for connecting the most isolated and forgotten refugees with the modern world.
