Bank of England policymakers have been slammed by UK newspapers in recent days for 'being asleep at the wheel'. Spiralling inflation, a 'cost-of-living crisis', a borrowing binge and an overheating labour market are being specifically pinned on lax UK monetary policy. And last week's UK data flow showing a further big jump in inflation, a steeper than expected drop in the unemployment rate and a record high for job vacancies have added more grease to the media's wheels.
But are these criticisms really justified? Well the answer is not quite, and for a number of reasons. The most straightforward reason being that these criticisms are not just being levelled at the BoE. They're also directed at the Fed, the BoC, RBA, ECB, and at many other central banks besides. In other words, many of these issues are globally-rooted and don't have their origins in lax domestic monetary policy.
Global roots
On the other hand, perhaps all of these central banks have been similarly asleep at the wheel during this period? Global monetary policy settings may have been far too loose for too long, particularly during the pandemic period. This could have generated too much money, excessive private sector leverage, and soaring demand. This could have now yielded outsized price pressures, wage price spirals thanks to overheating labour markets and dislodged inflation expectations to boot. If this isn't a wake-up call for policymakers to tighten monetary policy swiftly and aggressively and squeeze these excesses out of the system, then what is?
However, this global narrative and policy prescription doesn't quite hit the nail on the head either. There's no evidence – at the global level – for rampant money supply growth, for excess private sector leverage, or for economic activity more generally that's overheating. Price pressures have been, and still are, emerging due to acute supply side shortages that can mostly be traced to the pandemic or, more recently, to the conflict in Ukraine and China's zero COVID policy. And while a recovery in global demand has admittedly amplified these pressures, it has been fiscal policy – not monetary policy – that's been playing the supporting role.
All things considered, if that analysis is accurate, shouldn't monetary policy now play a bigger role in ameliorating these price pressures and, at the very least, preventing a bad situation from getting worse? This scribe is dubious. If loose and unorthodox monetary policies throughout the post-financial-crisis era failed to generate any consumer price inflation, and isn't really responsible for high inflation levels at present, why on earth should we expect tighter monetary policy to play a restraining role now?
More appropriate policy tools
Fighting the current combination of weak growth and high inflation with higher interest rates will not restore the supply fabric of the world economy not least now that most governments are tightening their fiscal stance at the same time. Surely a far more apt policy response (which admittedly the UK government is leaning toward) would be to use the levers of fiscal policy to alleviate supply-side shortages (e.g. in energy markets), increase an economy's production capacity and shore up the purchasing power of households and companies. By raising the cost of borrowing, tighter monetary policy will impede a supply side investment drive and further derail private sector purchasing power. As such, central banks may well make a bad situation even worse if they were to more actively respond to the pressures facing them from so many opinion formers in the media.
In what follows, we take a look at a few charts accompanied with (mostly) brief commentary reinforcing these messages.
The first chart in figure 1 below shows the strong link between commodity prices and consumer price inflation in the advanced economies over recent years. In short, consumer prices have been rising because input cost pressures have been rising.
