About this episode

This episode explores the concept of money through the lens of Yap's giant Rai stones and discusses the origins of currency and the myth of barter theory.

What is money? And what can a small island in Micronesia teach us about how it works? On Yap, a remote island in the western Pacific, giant calcite “Rai” stones once functioned as currency, where ownership and collective trust — rather than physical possession — defined wealth and status. In this episode of The Story of Money , macroeconomist and author Felix Martin joins hosts Gillian Tett and Robin Wigglesworth to explore the stones of Yap, the origins of money and why the traditional “barter theory” may be a myth.
