U.S. interest rates moved markedly higher following the election of Donald Trump as President. Some attribute this to better growth prospects, some attribute it to less foreign demand for U.S. assets, and others point to the possibility of higher inflation. After years of sub-2% inflation, higher inflation may be welcomed by the Federal Reserve (Fed). However, if inflation rises above 2%, how much inflation overshooting would the Fed tolerate before taking action? The Fed’s United Kingdom (U.K.) counterpart the Bank of England (BoE) may provide a good model to look at, as investors seek answers to this question

Inflation actions in the wake of Brexit

The BoE came out quickly post-Brexit with an aggressive stimulus program, cutting its bank rate, re-launching a government bond-buying program, and purchasing corporate debt. Lately, the U.K.’s economic data hasn’t been as bad as the BoE originally feared, which could stem from the fact that Brexit hasn’t happened, yet. For now, U.K. citizens can still travel freely throughout the E.U. and businesses can still sell into the E.U. market.

The pound’s decline has lifted inflation a bit, which has made British goods cheaper in the E.U.; it may also make it more profitable to sell British goods into the E.U. The converse is that goods sold by the E.U. into the U.K. have been either more expensive or less profitable for sellers. This has already caused a mini-crisis in the prices of some popular consumer goods. The BoE’s inflation forecasts have suggested that inflation could rise to 2.75%, which is well above the central bank’s 2% target. While the forecast indicates an inflation “overshoot,” the BoE said it will tolerate it. Anything above that reading and the BoE may need to tighten monetary policy.

A U.K. inflation overshoot should be temporary, if it’s only due to a weaker pound. Behind the scenes, prices would merely be adjusting to a new level—unless the pound continues to weaken. This is very different than a permanent increase in the rate of inflation; a one-time adjustment in the price level should only result in a temporary change in the inflation rate. Only if the price level keeps rising at a faster pace would it likely result in an actual increase in the rate of inflation—which is something the BoE would likely react to.

What can the U.S. learn from U.K. monetary policy?

Many central banks—especially the Fed—can learn from the BoE. The BoE’s innovation lies in how it communicates a limited tolerance for inflation overshooting. Energy and other commodity prices dropped in 2015 and early-2016. As we reach the anniversary of the depths of those price declines, year-over-year comparisons will make it look like inflation is picking up. Indeed, inflation may be picking up, but some of this is simply adjusting to a price level change and not necessarily a change in the trajectory of inflation. This will likely make it look like the U.S. is having an inflation overshooting issue, when it’s mostly just transitory.

By explicitly stating it was willing to tolerate inflation overshooting its target, the BoE gave the economy and investors room to handle these large year-over-year price adjustments without having to panic that inflation was running too hot. The central bank also provided a threshold for investors to watch as a guide to future changes in monetary policy. This helps brace people for higher inflation, but also sends a message that the BoE is on the watch and won’t let inflation rise too far.

What investors may want to keep in mind

Inflation is likely to be temporarily elevated, but should reset lower if commodity prices don’t keep moving higher.
Stocks may falter if concerns emerge based on this question: “What if inflation is more persistent than the Fed thinks?” That could mean less stimulus rather than more.
Bond yields could fall as the Fed would likely signal it has a watchful eye on inflation.
Commodity prices could fall and the dollar could strengthen as the Fed may decide to hike interest rates a bit more than currently anticipated.
