Kinky economics - When must fiscal policy tighten to combat inflation?

The prevailing mood in global macro discussions seems to be as follows; inflation is past its peak, but it is set to remain a lot higher for a lot longer than initially anticipated, forcing central banks to continue hiking, keep rates higher for longer, or a combination of the two. The interest rate shock in the UK, as markets have adjusted their expectations for the BOE bank rate higher, and hawkish comments from the ECB are the two most obvious cases in point in developed markets. But a surprise hike by the Bank of Canada, and a larger-than-expected hike in Norway have added to the sentiment. We only really need the Fed to be forced into a hawkish turn to complete the narrative. This shift is important for investors. We are not just trying to calibrate when central banks will pause their hiking cycles—probably soon—but we’re also increasingly discussing, and pricing, how long rates will stay elevated, and whether central banks will have to resume hiking before they cut. Higher-for-longer, or #H4L, is already a trending hashtag on FinTwitter.

Can we pull off a soft landing?

Central bank hiking cycles in the developed world are slowly but surely coming to an end, raising the question of whether they have pulled off a soft landing, defined as a fall in inflation back towards target of around 2% without a meaningful decline in output and rising unemployment. On the face of it, the answer to this question is a resounding no. Interest rates in Europe, the UK and the US are up anywhere from 300 to 450bp in less than a year, driving up bond yields , and pushing yield curve inversions to near record levels. Anyone using these data points to predict what comes next, using historical relationships, will conclude that the wheels are about to come off in developed economies and their financials markets alike. The difficulties in the US regional banking sector is, in this case, simply a canary in the coal mine, warning of bigger shocks to come. The investment implications of such a view are simple; short equities and long short-term government bonds.

The latest front in the macro wars

The skirmishes in the macro wars are getting dirtier. More recently, the debate on inflation has pitted #TeamTransitory and its detractors—I’ve seen the other side described as #TeamPermanent and #TeamSustained—in a mud-slinging and, often emotionally charged, spat. I suspect that #TeamTransitory will win, eventually—whatever that means—though I also think this side of the debate has most to answer for in terms of the deteriorating debate. The rules seem to change as the consensus-beating inflation prints roll in. As I as explained here, it is unreasonable to term all versions of the world in which inflation is not making a new high on a monthly basis, as a transitory. More importantly, however, the checkmate-like rebuttal to anyone arguing that rates could and should go higher that they must be in favour of higher unemployment is particularly odd to me. The question we need to ask it seems is whether there are conditions under which policy tightening—both fiscal and monetary—to rein in demand are optimal or desirable, in an economic sense, even if it means, presumably, unemployment going up. The answer is; yes.

Wanted: A Theory of Inflation

The more I think about the current debate about inflation, the more I am inclined towards the following remarkable conclusion. We currently do not have a good framework to explain inflation, neither cyclically nor structurally. Perhaps more appropriately, the old consensus among economists and policymakers on what inflation is, how it arises, and what to do about it has been severely challenged, if not shattered entirely. In a post-pandemic world of a clear, and almost textbook, inflationary mismatch between demand and supply, this has created the odd situation in which everyone is talking about inflation, and more recently inflation expectations, concluding that it either doesn’t matter or that we don’t understand how inflation works in the first place. Nowhere is this clearer than in the debate about whether presently high inflation is transitory or not. The thrust of this discussion has as much to do with the main interlocutors convincing each other that high inflation doesn’t matter, as it is about agreeing on what, in fact, transitory means.
