'The Great Inflation' is a momentous period in US economic history that lasted for 17 years between 1965 and 1982. During this time, the world's largest economy experienced high levels of inflation that even went into double digits.
History books tend to attribute the blame to the US Federal Reserve that was complacent about potential increases in inflation and instead, was too fixated on tackling unemployment. The painful memories of the 1930s and the Second World War had a role to play in this.
We live in a undoutedbly different world today, but certain parallels can still be drawn. The Fed's current stance is that inflation is likely to be transitory. The central bank is therefore in no real rush in pulling back its unprecedented monetary accommodation which it introduced during the Covid crisis.
Markets, it appears, do not share the view given inflation expectations are continuing to rise.
Why might markets be challenging the narrative the Fed is currently subscribing to? There are potentially four reasons.
First, the confidence markets have on the Fed's ability to control inflation without creating tectonic shifts in asset markets may be diminishing. This is evident from the short and sharp spikes in the CBOE Volatility Index (VIX) around the Federal Open Market Committee meetings this year.
While supporting financial markets may not be part of the Fed's mandate, the central bank has become increasingly conscious of market movements in recent times.
Second, realised levels of inflation have started rising more broadly. Most recently, the eurozone's annual inflation rate has accelerated to 2% in May, up from 1.6% in April, and above consensus forecasts of 1.9%.
While such readings are influenced by so-called base effects - i.e. the increase in the prices of inputs such as oil - inflation could be sustained at a higher rate if commodity prices continue to rise and a commodity supercycle is indeed underway.
Third, the pandemic has induced a renewed focus on fiscal stimulus from governments around the world to induce growth. This was not the case for many major economies after the Global Financial Crisis.
From US President Joe Biden's $2trn infrastructure pledge to the €2trn European Union stimulus, the focus from governments is clear: the world needs better infrastructure. If monetary accommodation alone does not prove inflationary, fiscal stimuli could end up tilting the scales.
The fourth factor is pent-up demand from consumers as well as businesses. Consumer spending in the US increased to pre-pandemic levels of around $13.4trn in Q1 2021 from $13trn in Q4 2020.
If the pandemic can be characterised as the economic engine being parked rather than broken, pent-up demand could quickly cause consumer spending to overshoot the trend from recent years.
So, what can investors do? There are numerous ways to hedge against the risk of inflation, but broad commodities appear to be in favour among investors right now.
Flows into broad based commodity exchange traded products have exceeded $11bn this year, with reflation among the key trends likely to be catalysing the trend.
Similarly, gold has been rejuvenated since the start of the second quarter this year staying true to its nature of responding more to actual increases in inflation rather than inflation expectations.
And if inflation is to surge to levels reminiscent of the 'The Great Inflation', gold's relevance could be here to stay.
How persistent inflation turns out to be is likely to remain an ongoing debate. How investors choose to tackle the risk in their portfolios will probably also be a key consideration going forward.
