How should you invest in times of high inflation

One story has dominated the economic news in 2022 — inflation. Around the world, prices have risen far faster than forecasters were expecting, as a result of knock-on effects from the Covid-19 pandemic, the war in Ukraine and strong consumer demand. 


The inflation rate in Ireland hit a 38-year-high of 9.1% in June and July, though it did fall slightly, to 8.9%, in August, and again, to 8.2% in September. One crumb of comfort is that prices have risen more slowly in Ireland than in many other countries, including the UK. But it’s still a pretty grim picture, and it’s not surprising that investors are concerned about the impact of inflation on their portfolios.


As we explained in our last article, 2022 has been one of the toughest years on record for investors. That’s because, unusually, bonds have fallen in value as well as equities. As a result, all investors — cautious, balanced and adventurous ones — have been badly hit. 


The question is, what should investors do now, given the inflationary environment we find ourselves in?


The temptation at times of great economic uncertainty is either to flee the markets altogether or to succumb to the siren song of fund managers, as well as many advisers and consultants, and sign up for an expensive active investment strategy. 


But new research by Global Systematic Investors suggests that sticking with a broadly passive, evidence-based approach is a much more sensible. Here are four key takeaways from the GSI study.



1. It’s very unlikely that you won’t be negatively impacted


The bad news is that, whatever you invest in, it probably won’t insulate you from the effects of inflation. Cash is an obvious example. Bonds fall in value too as a direct result of increasing yields.


Normally, bonds and equities are negatively correlated; in other words when bonds fall, equities tend to rise. But inflationary periods are an exception. Rising prices increase economic uncertainty, and companies are often unable to pass on the increased cost of raw materials to their customers, which in turn reduces profits.


Because commodity prices usually rise when inflation accelerates, investing in commodities may provide portfolios with a hedge against inflation. The problem is, of course, that investing in commodities now is like closing the stable door after the horse has bolted. Prices have already shot up, and the possibility of further rises in inflation is effectively baked into them. 



2. Predicting movements in inflation is extremely hard


Of course, things would be so much simpler if we knew, in advance, how much further prices would rise or how long inflationary periods would last for. But it’s extremely difficult to tell. Some forecasters are very downbeat, others more optimistic, and they can’t all be right.


A US study in August 2021 showed that higher inflation (roughly rates of more than 5%) is sometimes temporary, lasting just a few months. But there are several examples of high-inflation periods lasting at least two-and-a-half years. On two occasions since the Second World War, they’ve lasted around four years. The most recent example came in the economic boom of the late 1980s.


It’s highly likely that the the worst of the current inflationary environment is already behind us. In Australia, the federal government and Reserve Bank have forecast that inflation will peak at 7.75% by the end of this year, and then fall over the next two years. But forecasts for other countries are more pessimistic.



3. Markets may rebound strongly as inflation falls


It’s almost always a bad idea to sell once prices have already fallen sharply. Why? Because eventually markets recover, often quite quickly, and it’s very hard to predict when prices will start rising again. As the chart below demonstrates, US equities in particular tend to rebound strongly after inflationary periods. For example, in the two years that followed the crisis caused by the OPEC oil embargo in the early 1970s, US stock markets rose almost 30%.


Of course, inflation could persist for longer than analysts anticipate. But, by the same token, it could ease off far sooner. If you switch into cash now, it might provide you with some emotional relief in the short term, but it could mean missing out when prices recover. 




4. A diversified, factor-based approach makes sense


As I’ve already explained, most major asset classes are negatively affected by inflation. But is there anything you can do to try to reduce the damage? GSI’s research suggests there is.


Bernd Hanke, the study’s author, says: “The best strategy in times of inflation is to stick with an asset allocation that gives you the highest expected risk-adjusted return overall. Global diversification can help protect returns. You can also use a factor approach as a potential cushion.”


Factor-based investing means increasing your exposure to different risk “factors” which, research has shown, tend to produce higher returns over time. These include small companies, value stocks and companies with high profitability. As the chart below shows, focussing on factors has been a successful strategy over time, regardless of inflation. 



 These are uncomfortable times for investors, and the sad fact is that fund managers and even many financial advisers will try to exploit that discomfort and sell you a strategy that appears to provide a solution.

 But, as we’ve said before, no one has a crystal ball — either about inflation and the economy, or the future direction of the financial markets. The best approach is to stay calm and disciplined, and to stick to a strategy that’s founded on data and evidence.

Warning: The above is general in nature and should not be taken as advice.
Warning: The value of your investment may go down as well as up.
