Executive Summary

We have a relatively sanguine view on the likelihood of inflation becoming ingrained in the system (much as it pains us to agree with the Fed). However, the dark arts of macroeconomics are notoriously tricky, and we have often talked of the need to build robust (as opposed to optimal) portfolios – effectively, portfolios that can withstand multiple outcomes. As such, it behooves us to consider how to deal with inflation in the context of your portfolio. The first choice you must make is to determine whether you are interested in an inflation hedge (something that closely tracks inflation) or a store of value (something that will preserve purchasing power). For long-term investors, the latter is probably of more interest. A focus on the store of value naturally leads to a search for real assets. Despite conventional wisdom, commodities in general haven’t been a good store of value. The ‘best’ real asset we have found is equities. They make a terrible inflation hedge but over the long term they are the businesses that charge prices and pay wages, so their cash flows should be real if these two elements are roughly matched, and thus they act as a store of value in the longer term. Of course, you can do better than simply buying equities, you can buy cheap equities. This is like being offered inflation insurance at a discount.

Hedging Inflation Risk Today

We have a relatively sanguine outlook on inflation, as discussed in “Part 1: Inflation – Tall Tales and True Causes.” Perhaps you don’t share our view. Or perhaps like us you are always interested in how to build a robust portfolio (one which can survive a lot of different outcomes). Either way it is time to turn our attention to how to protect your portfolio from an inflationary outcome.

As with all ‘tail risk’ insurance you need to ask yourself the three questions that one of us laid out a long time ago.1

1.What are you trying to hedge?

In this case, we need to consider the sources of inflation. Unfortunately inflation seems to follow the Anna Karenina principle. As Tolstoy put it, “Happy families are all alike; every unhappy family is unhappy in its own way”. The ‘good’ news is that the labour market dynamic is truly key for an inflation to take hold so pondering this aspect may make it slightly easier to think about, rather than trying to find the proximate cause.

2. How will you hedge?

We will explore some of the options that you might choose to pursue in the next section of this paper.

3. How much will it cost to hedge?

As always, it is important to remember that insurance is as much a value-based proposition as anything else in investing. So you need to be sure to analyse the cost of the insurance that you are buying.

Before we look at the potential ways you might try to hedge inflation, we need to make a distinction between what we might call hedging and a store of value. We think this is a vital distinction. To us, the term hedge implies a tight correlation with inflation (and therefore takes you into the world of swaps and caps, etc.). The concept of store of value is probably more important to a long-term investor. We think of this as an asset that should outperform inflation but isn’t necessarily closely correlated with inflation (especially in the short term). Equities (assuming fair value for a second) are a real asset and we should expect their underlying cash flows to keep pace with inflation over the long term. As such, they meet the criteria for a store of value. However, due to behavioural issues, sometimes valuations get compressed in inflationary times, so they don’t correlate well with inflation as a hedge. Hence, they are a store of value but not an inflation hedge. Figuring out which of these two dimensions is important to you is vital when it comes to the choices you will make.

Let’s turn to the various instruments that might be thought to act as either a hedge or a store of value when it comes to inflation.

Treasury Inflation-Protected Securities

The single most obvious inflation protection is, of course, Treasury Inflation-Protected Securities (TIPS). These are truly indexed to the CPI and have the full faith of the US government behind them. The price you are paying is very clear: right now you are paying around 1% for the privilege of not having to worry about inflation. Obviously, one could also view the inflation breakeven (aka the market’s view of the likely rate of inflation). Currently this market is suggesting inflation of around 2.4% p.a. over the next decade as shown in Exhibit 1.

Inflation Caps

An instrument closely related to the above is an inflation cap. These derivative instruments pay out if inflation is higher than the chosen level. For instance, Exhibit 2 shows the price of a 10y 2% inflation cap. Once again, there is no doubt at all that these instruments will hedge inflation, but they do have greater counterparty risk than TIPS.
