The current economic, inflation, and interest rate cycle has been extremely unusual, driven by the worst global pandemic in over 100 years. Governments around the world reacted in a variety of ways. In the US, one of the governmental responses was to create negative real interest rates as well as issue record amounts of stimulus money into the economy. The US Federal Reserve, uncertain about the outlook for the economy and the affect Covid would have on the consumer and businesses, was fearful to raise interest rates and choke off any economic recovery. As a result, as inflation moved higher in the US, driven by the end of Covid lockdowns and aided by the previously mentioned government stimulus and negative real rates, the Federal Reserve did not react promptly. This resulted in a large gap between the Fed Discount rate and inflation. As seen in Figure 1, the gap reached record levels in 2022 and left the Federal Reserve greatly behind the current economic conditions.

History clearly shows worse performance for the US stock market while the curve is inverted. However, note that the sample size for inversion periods is fairly small at only 11% of all weeks since 1970. Figure 2 demonstrates that the further our from each week the curve is inverted, the greater the negative returns have been.
On a more granular basis, the worst forward equity market performance occurs when the yield curve is inverted between -51 to -100 basis points, which is the present situation. Historically, when this occurred, forward six-month returns were -4.2% to -5.7%. The table in Figure 3 details four- to 52-week returns based on the shape of the yield curve.
Since November 2022, returns have gone against historical averages. In just over nine months since the curve inverted, the S&P 500 is still up around 9%, despite having given back 5% recently. The year-to-date market continues to be an outlier, although continually going against history seems like an uphill battle.
Historically, the stock market has tended to have significant selloffs when the curve steepens from a low or inverted level (see 1970, 1980, 1982, 2003, 2007 in Figure 4). Normally the steepening during inversions occurs from the short end of the yield curve falling as opposed to the long end rising as has happened this year. Also, bear markets during a curve flattening and inverting are rarer but have occurred as well (1973, 2022).
As seen in Figure 5, there is not much difference between a steepening or flattening yield curve overall. However, in either case, an inverted yield curve has resulted in weak stock market averages. A yield curve that is both inverted AND steepening is essentially the worst scenario, although it also has the fewest occurrences. This is potentially the current situation. For calculation purposes, we used a curve change over a four-week period for this section.

As seen on the Datagraph™ in Figure 6, US 10-year yields have broken a multi-decade downtrend. It is possible that the Federal Reserve may raise interest rates again. If this occurs, US 10-year yields could approach 4.75%-5%, which would likely be a negative for stocks.

Figure 7 below demonstrates sector performance when the yield curve is positively sloped, and Figure 8 shows sector performance when inverted. If there is a positive takeaway from these tables, it is that the commodity sector has a history of positive returns (see Basic Material and Energy), when inverted. On the other hand, performance has been worst for the Consumer Cyclical, Technology, and Financial sectors with an inverted curve.

With this backdrop, we suggest at least part of a portfolio dedicated to stocks that may be a counterbalance. This includes companies with lower debt ratios, strong long-term earnings growth and stability, high return metrics (return on invested capital, return on equity). Figure 9 lists a handful of stocks that score highly on these metrics, and which are also acting very well amid the recent general market weakness.

In conclusion, if one uses history as a guide, the current inverted and steepening yield curve normally portends negative returns for equities over the coming three-to-twelve months. Given the strong performance year-to-date in US stocks, with the NASDAQ up roughly 30%, we believe investors should be cautious. The stock market appears to be at a particularly vulnerable point given the uncertainty concerning the economy, interest rates, and inflation. Until there is greater visibility on some or all of these factors, investors should proceed carefully.
