Hedging Equity Portfolios with Treasury Futures During Yield Curve Inversions

Why Hedge with Treasuries During an Inversion?

A yield curve inversion is one of the most reliable leading indicators of a recession, and recessions are typically accompanied by significant equity market drawdowns. During these periods, long-term Treasury bonds have historically exhibited a negative correlation with equities, making them an effective hedge. As fear grips the market, investors flock to the safety of government bonds, pushing their prices up and yields down. This flight-to-quality dynamic is the cornerstone of using Treasuries as an equity hedge. Treasury futures provide a liquid and capital-efficient way to gain this long-bond exposure.

Constructing the Hedge

The most common instruments for this hedge are the 10-Year Treasury Note futures (ZN) and the 30-Year Treasury Bond futures (ZB). To hedge an equity portfolio, a trader would take a long position in these futures contracts. The size of the hedge depends on the desired beta-adjusted hedge ratio. A simple approach is to calculate the dollar value of the equity portfolio and then buy an equivalent dollar value of Treasury futures, adjusted for their duration. For example, to hedge a $1 million equity portfolio with a beta of 1.0, a trader might buy approximately 10 ZN contracts (assuming a notional value of around $100,000 per contract). A more precise method involves calculating the portfolio's beta to the S&P 500 and then using the historical correlation between the S&P 500 and Treasury futures to determine the optimal hedge ratio.

Entry and Exit Signals

The signal to initiate the hedge is the inversion of a key part of the yield curve, such as the 2s/10s or 3m/10y spread. A common rule is to enter the hedge once the spread has been inverted for a full month to avoid false signals. The hedge should be maintained as long as the curve remains inverted and the economic data continues to deteriorate. The signal to exit the hedge is typically the steepening of the yield curve back into positive territory, which often coincides with the bottom of the equity market and the beginning of a new economic cycle. At this point, the negative correlation between stocks and bonds tends to break down, and the hedge is no longer effective.

Risks and Considerations

While historically effective, this hedge is not without its risks. The negative correlation between stocks and bonds can break down, particularly in an environment of high and rising inflation. If both stocks and bonds fall together, the hedge will fail. This was seen in 2022, when high inflation caused the Fed to hike rates aggressively, leading to losses in both asset classes. Therefore, it is important to monitor inflation expectations and Fed policy when implementing this strategy. Additionally, the cost of carry for the futures position must be considered. If the yield curve is steeply inverted, the negative carry on a long futures position can be a drag on performance.
