US inflation is on the rise, but it is certainly not on the run by any stretch of the imagination. In fact, the core Consumer Price Index (CPI) rose 2.2% in September—less than economists expected, dragged lower by declining car and truck prices.1

But after years of accommodative monetary policy meant that inflation felt pretty much non-existent, it is now hovering persistently around the Federal Reserve’s 2% target. While September’s CPI reading missed expectations, core inflation remains above 2%.2 Steady consumer demand, late-cycle fiscal stimulus, accelerating wage growth and increasing import prices are fueling its return. The proposed 25% tariff on $200 billion of Chinese goods, which include a wide range of consumer products, may add more upside risk to inflation in 2019.3 With rising oil prices and a steady increase in input prices, more attention is being paid to managing inflation risk in portfolios.

Investors looking to implement inflation management strategies often turn to commodities, which are typically purchased using futures contracts. But this approach may not be as effective as many believe, and there is another solution investors can consider to efficiently add a commodities exposure: natural resources ETFs.

The imperfect nature of commodity futures contracts

Most commodity investments are linked to futures contracts, which are traded via spot instruments, because physical custody of commodities is nearly impossible for most market participants. Though futures contracts are the popular choice, they can have a downside.

With futures, investors must contend with roll yield. Roll yield describes the profit or loss that results from selling existing contracts and then purchasing, or rolling, into longer-dated contracts. If the longer-dated contracts are more expensive than the currently held contracts—the result of an upward sloping futures curve—the cost of rolling can eat away much of an investor’s total return.

As shown below, the return profile of a futures-based commodity index can diverge significantly from an index based on spot prices, primarily due to the impacts of roll yield. In the last 20 years, the Bloomberg Commodity Spot Index advanced more than 270%, while the Bloomberg Commodity Index declined 2%. In the past year through September 28th, the Bloomberg Commodity Spot Index advanced 5%, doubling the 2.5% gain of the Bloomberg Commodity Index.

Another commodity-driven solution to inflation: Natural resources ETFs

Outside of the spot and futures markets, there is another means of achieving inflation-fighting commodities exposure: the equities of natural resources firms. These businesses are primarily involved in metals and mining, agribusiness and energy. Exposure to these companies via ETFs can be an efficient—but often overlooked—way to harness commodities without the slippage of futures contracts.

Historically, shares of natural resources companies have performed well in inflationary environments because earnings are closely linked to the value of the underlying commodity produced by the firm. As such, when inflation erodes the value of the US dollar, the value of the underlying commodity and the firm’s shares both rise.

As shown below, shares of natural resources companies have historically moved along with inflation expectations.

In addition, natural resources ETFs provide investors with equity risk premium, a valuable benefit not afforded traditional commodity investments. Since early 2017, when inflation started to pick up, the S&P® Global Natural Resources Index has advanced 22%, besting the Bloomberg Commodity Spot Index’s 7.5% increase.4

What about valuations?

Overall global equity market valuations are near historical highs based on price-to-earnings, forward price-to-earnings and price-to-book ratios. However, the chart below shows natural resources stocks are trading near their 10-year medians, leading to below-average valuations relative to the broader market and presenting a value opportunity.

When taking into account the structural factors that could drive demand for natural resources and the value of the firms’ physical assets, natural resources stocks may represent a value opportunity with inflation-fighting power to boot.

Investors seeking exposure to natural resources can consider an allocation to the SPDR® S&P Global Natural Resources ETF (GNR) and the SPDR S&P North America Natural Resources ETF (NANR).

Financial contracts that obligate buyers and sellers to buy or sell an asset—often physical commodities or financial instruments—at a predetermined future date and price. Futures contracts also stipulate the quality and quantity of the underlying asset and are standardized to facilitate trading on a futures exchange. Some futures call for physical delivery; others are settled in cash.
