A recent New York Times article called it floating traffic jams: huge container ships queuing to enter port[1]. They are manifestation of the supply/demand imbalances caused by the Covid-19 pandemic. To make matters worse, there is now concern that the grounded container ship might block the Suez Canal as long as a week, which would imply more supply disruption and temporarily higher prices, due to shortages and the longer, more expensive alternative route around Africa.

Analysing and forecasting inflation is a complex matter. It starts with the need to see the forest from the trees. One-off factors –e.g. extending the sales period- and base effects –such as a temporary reduction in the VAT rate in Germany last year- complicate the interpretation. Short-run dynamics may be quite different from longer-term trends. In recent months, purchasing managers in the euro area and the US have reported a significant increase in input prices as well as longer delivery lags. Almost inevitably, the disruptive impact of the pandemic on demand and supply is causing an imbalance when demand recovers and supply is struggling to follow. The shortage of semiconductors is a case in point. The supply side reaction to the pandemic is clearly an issue in the US. The Federal Reserve Bank of Atlanta recently analysed the swift, significant increase in its District’s business inflation expectations survey. More than 50 percent of companies surveyed report delayed deliveries whereas uncertain pandemic-related employee availability is weighing on production capacity. “Firms experiencing the most intense disruption tend to be those with the highest expectation of future inflation.”[2] It remains to be seen whether this will convince companies to raise their prices. This depends on factors such as competitive pressures, the price elasticity of demand as well as demand growth. In the US, the latter will get a boost from the USD 1.9  trillion American Rescue Plan. In this respect, the Atlanta Fed researchers finely note that their explanation of rising inflation expectations “tamps down the speculation that the potential inflationary impact of recent fiscal stimulus on demand is behind heightened year-ahead inflation expectations.” To put it differently: should the fiscal stimulus cause heightened inflation expectations, it still has to show up in the data.

Fed chairman Powell has acknowledged there could be bottlenecks, adding however that the increase in inflation should be relatively modest and transient because the supply side is very dynamic. “People start businesses, they reopen restaurants, you know, the airlines will be flying again, all of those things will happen. And so it’ll turn out to be a one-time sort of bulge in prices, but it won’t change inflation going forward. Because inflation expectations are strongly anchored around 2 percent.”[3] Until the pandemic, the longer-term expected change in unit costs per year –a factor which influences price-setting behaviour of companies- has fluctuated in a narrow band of about 40 basis points. Likewise, consumer 5 year inflation expectations –which could influence wage demands- and 10 year inflation expectations of professional forecasters –a measure of central bank credibility- exhibit very limit cyclical amplitude. There is some correlation between recently observed inflation and inflation expectations –which is suggestive of extrapolative behaviour- but the transmission from the former to the latter is small. Notwithstanding these observations, the second half of the year will see a lot of nail-biting as US inflation data are released in an economy that, on the back of a very successful vaccination campaign, accommodative monetary policy and massive fiscal stimulus should be able to close its output gap quickly.
