Worries about global currency wars have resurfaced in recent weeks, mainly because of Japanese action on the yen. This is only the latest of several such flare-ups since the 2008 financial crash. It is hard to avoid the suspicion that the unconventional monetary policies of the US, UK and others are designed to drive down their exchange rates in order to indulge in “beggar thy neighbour” policies of the type which Samuel Brittan has condemned.

Currency wars strike dread into the hearts of most economists because they contributed greatly to the severity of the Great Depression in the 1930s, especially in the worst phase from 1931-33. The damage done to global trade in that period took several decades to repair, and a repeat of this nightmare cannot be entirely ruled out.
