This study divides the world into currency zones according to the co-movement of each currency with the key currencies. The dollar zone groups economies that produce well over half of global GDP. The euro zone now includes almost all of Europe and some commodity producers, but remains less than...

What would balance sheets look like if the borrowing through FX swaps and forwards were recorded on-balance sheet, as the functionally equivalent repo debt is? We combine various data sources to estimate the size, distribution and use of this "missing" debt and to begin to assess its...

Covered interest parity verges on a physical law in international finance. And yet it has been systematically violated since the Great Financial Crisis. Especially puzzling have been the violations since 2014, even once banks had strengthened their balance sheets and regained easy access to...

This paper studies the ongoing diffusion of renminbi trading across the globe, the first such research of an international currency.

Global turnover in non-deliverable forwards (NDFs) continues to rise in aggregate. But the paths of NDF markets have diverged across currencies: renminbi internationalisation has led to rapid displacement of NDFs by deliverable forwards, while the NDF market has retained or even gained in...

A long-standing puzzle in international finance is the durability of the dollar's share of foreign exchange reserves - which remains above 60%, while the weight of the US economy in global output has fallen to less than a quarter. We argue that the dollar's role may reflect instead the share of...
