Previously I argued that the Reserve Bank's credibility is a critical defence against a repeat of the 1970s stagflation experience. That is true, but it is only half the story. The other half is the architecture around the central bank, which determines whether that credibility can do its work.
This post is about the broader architecture necessary to manage inflation, told through the question that the set of charts below forced me to confront: Why did Australia take so much longer than everyone else to get inflation back under control after the 1973 oil shock? The UK, Japan and Italy all had an inflation peak higher than Australia's in the wake of the oil shock. All were broadly back towards pre-shock inflation levels in three to eight years. Australia took 15+ years.
