Central banks have been labelled exotic beasts: rarely seen in public, much less understood. Realisation of what central bankers do has been seeping in slowly. Over the past few decades, as bond and currency trading acquired gargantuan proportions, the arcane world of dealers kept a close watch on every statement coming out of central banks, parsing each phrase and analysing each nuance. Any action, or the faintest hint of a future one, had the potential to affect currency prices, bond rates and individual fortunes. This need for analysis and interpretation also produced a large tribe of writers called ‘central bank watchers’.
