Inflation Continues to Cool

Falling Oil Prices Create Deflationary Tailwind

SUMMARY

  • Falling oil prices are a moderating influence on inflation, reducing ‘Stagflation’ risk.
  • This is positive for US stocks. However, low oil prices are a negative for the energy sector, in our view.
  • Tariff uncertainty delays Fed action.

The April Consumer Price Index (‘CPI’) report was released last Wednesday and gave the Federal Reserve another positive data point in its inflation fight, as did Thursday’s negative Producer Price Index (‘PPI’). Headline CPI fell for the fourth consecutive month and is trending towards the Fed’s stated, long-term inflation target of 2% (see chart 1, below). While consumer prices are unlikely to have been affected much by tariff policy yet, it appears from parsing PPI that companies are trying to shield consumers from large price increases. Regardless, we still view this as a positive sign, given the concern surrounding those tariffs and their effects on inflation. We have spilled much ink over the last several weeks discussing tariffs and instead would like to focus on oil prices and their impact on inflation. Oil prices are particularly interesting since they tend to be both a direct and indirect driver of inflation… meaning they impact core CPI and other indicators that the Fed is watching, even when oil prices are explicitly removed.

Inflation and Oil Prices: Closely Correlated

One of the major reasons we believe we have seen a continued downward trend in CPI is lower oil prices. In fact, looking at Chart 1 (below) we can see the relationship between West Texas Intermediate (WTI) oil prices (left axis) and CPI (right axis).

This chart illustrates a strong relationship between the price of oil at the beginning of the month and the eventual CPI print for that month and shows the two data sets have a high correlation of roughly 0.8. As stated above, oil prices, as an input of CPI, directly drive inflation, but energy only makes up 7% of the CPI basket. Therefore, there must be second order effects present that cause the correlation between oil prices and CPI. Additionally, the correlation between CPI ex-Food and Energy (‘Core CPI’) is equally robust. As its name suggests, core CPI removes price changes in energy, so any correlation between oil prices and core CPI must come from second order effects.

Last month, the Organization of the Petroleum Exporting Countries (‘OPEC’) announced an increase in their output that, along with concerns about the global economy, sent WTI prices below $60 per barrel. While they have recovered to the low $60’s in the past couple of weeks, we believe the leading relationship between oil and CPI implies that May should provide further relief on the inflation front.

Conclusion: Falling Inflation Positive for Stocks…

Within the framework of our scenario analysis, which we discussed in last week’s Weekly View, relatively tame inflation moves our probabilities more towards positive scenarios for the US stock market and reduces the odds of ‘Stagflation’. Specifically, if inflation remains benign, it allows the Fed more room to support the economy with rate cuts, if necessary. Lower rates are also a key element of a ‘Value Rotation.’ For most value-centric sectors such as cyclical industrials, materials and smaller-capitalization companies, their debt and interest expenses are very close to market interest rates. As such, when the Fed reduces rates, these companies can get a reprieve from this debt burden and their ‘operating leverage’ (how much of a company’s top-line revenue can be converted into bottom-line earnings and cash flow) can be unlocked.

While falling oil prices give optimism for continued moderate inflation, the impact of tariffs still looms. If high tariffs come back on to the negotiating table, the moderating of inflation becomes much less certain. Even with lower blanket tariff rates of around 10%, the effect on CPI is likely to be a one-time increase of at least a percent, in our view. All of this is especially important given the Fed’s ‘data dependent’ stance. As demonstrated by their current pause, the Fed is willing to let economic data play out completely before they return to their cutting cycle; the Fed is not willing to over-extrapolate a single data point to justify cutting interest rates. Instead, we believe the Fed is going to wait for tariff negotiations to play out before they access their impact, especially while the job market remains resilient. As such, we currently are not expecting a cut this year, meaning any value rotation is placed on the back burner.

…But a Headwind for the Energy Sector

While we still believe ‘breakevens’ (the price of oil that makes drilling a certain well economically beneficial for an energy company) for the US energy sector are below current oil prices, the recent fall in price has made this margin tighter. Additionally, as we discussed above, we have recently reduced our probabilities of an entrenched ‘Stagflation’ scenario. In RiverFront’s asset allocation portfolios, we have utilized US energy allocations in the past to help hedge the portfolio against the risk of this particularly negative scenario. Taking both falling oil prices and the change in our scenario analysis, we have reduced our energy exposure and are now currently close to neutral energy weight relative to our benchmarks. The energy positions we do hold have a focus on US energy over international energy producers. In our longer-time horizon portfolios, we also emphasize individual energy companies with a strong management team and access to investment grade debt.
