Rebalancing When Cash Yields Remain Relevant

Introduction

As of early September 2024, cash yields remain a relevant consideration for portfolio construction and rebalancing. The Federal Reserve's interest rate trajectory, ongoing market volatility, and the shifting economic landscape have kept short-term yields elevated relative to the past decade. For investors, this environment presents both opportunities and challenges when rebalancing portfolios. The traditional logic of holding cash as a drag on returns may need revisiting, as cash now offers a competitive yield and a buffer against uncertainty. This note explores how to approach rebalancing when cash yields are still relevant, using only information available as of 2024-09-02.

Market Context

Markets in mid-2024 have been dominated by intense speculation about the timing and magnitude of Federal Reserve easing. After a prolonged tightening cycle, the Fed has held rates steady at elevated levels, but market participants are pricing in potential cuts later this year and into 2025. The uncertainty surrounding the pace of disinflation, labor market resilience, and global growth has kept bond yields volatile. Meanwhile, U.S. election uncertainty, shifting China policy expectations, and geopolitical risks add layers of complexity. Against this backdrop, cash yields—particularly on Treasury bills and money market funds—have remained attractive, often exceeding 5% annualized. This has led some investors to question the traditional equity and bond allocation and consider a larger cash position.

Rebalancing with Cash: A Tactical Approach

Rebalancing is a disciplined process of restoring a portfolio to its target asset allocation. Typically, it involves selling assets that have risen in value and buying those that have fallen. In the current environment, cash can play a dual role: as a safe haven and as a source of yield. When rebalancing, investors may consider the following:

1. Locking in Gains: Equities have had a strong run in certain sectors, particularly technology and AI-related names. Rebalancing by trimming overvalued positions and moving proceeds into cash can lock in gains and reduce portfolio risk. This is especially relevant if the investor's risk tolerance has not changed but market valuations have become stretched.

2. Building Optionality: Holding cash provides the flexibility to deploy capital when opportunities arise. Given the uncertain economic outlook, cash acts as a dry powder that can be used to buy assets at distressed prices if a downturn occurs. This is a key consideration for long-term investors who want to avoid being forced sellers during market declines.

3. Yield Enhancement: With cash yields still elevated, holding cash is not as punitive as in the low-rate environment of the 2010s. In fact, cash can be considered a tactical asset class that competes with bonds on a risk-adjusted basis. For example, short-term Treasury bills offer a yield that is comparable to or higher than many investment-grade bonds, with lower duration risk.

4. Reducing Correlation Risk: Cash has zero correlation with other asset classes, making it an effective diversifier. In a portfolio that is heavily weighted toward equities and bonds, adding cash can reduce overall volatility and protect against simultaneous declines in both stocks and bonds.

Implications for Investors

For institutional and individual investors alike, rebalancing into cash should be approached with a clear framework. The decision to hold cash as a tactical allocation should be based on the investor's time horizon, liquidity needs, and market outlook. As of September 2024, the following considerations are pertinent:

• Time Horizon: Short-term investors (under one year) may benefit from holding cash to avoid market timing risks. Longer-term investors should be cautious about deviating too far from their strategic asset allocation, as cash returns may not keep pace with inflation over extended periods.

• Liquidity Needs: Cash provides immediate liquidity, which is valuable in uncertain times. If an investor anticipates large expenses or margin calls, holding excess cash can prevent forced asset sales at inopportune moments.

• Market Outlook: The consensus view as of mid-2024 is that the Fed will begin cutting rates in late 2024 or early 2025. If this materializes, cash yields will decline, reducing the attractiveness of cash. Investors should be prepared to redeploy cash into longer-duration assets as yields fall. However, if inflation proves sticky or the economy remains strong, rates could stay higher for longer, making cash a more permanent fixture.

Risks to Watch

While cash offers benefits, there are risks to holding too much cash:

• Reinvestment Risk: When the Fed eventually cuts rates, cash yields will drop. Investors who lock in high yields now may face lower returns when they need to reinvest maturing instruments.

• Inflation Risk: Cash yields, while attractive, may still be below the inflation rate. Over time, holding cash can erode purchasing power. This is a particular concern for long-term investors.

• Opportunity Cost: By holding cash, investors miss out on potential capital appreciation in equities and bonds. If markets rally, cash underperforms. The key is to strike a balance between caution and participation.

• Behavioral Pitfalls: Rebalancing into cash can become a form of market timing if not done systematically. Investors may be tempted to increase cash holdings during market declines out of fear, or to reduce cash too early in anticipation of a rally. A disciplined rebalancing plan helps mitigate these biases.

Closing

As of September 2024, cash yields remain a relevant factor in portfolio rebalancing. The elevated rate environment, combined with economic and political uncertainty, makes cash a valuable tactical tool. However, investors should avoid viewing cash as a permanent solution. Instead, it should be used as part of a disciplined rebalancing strategy that adjusts to changing market conditions. By locking in gains, building optionality, and managing risk, investors can navigate the current landscape while staying focused on long-term objectives. The key is to remain flexible and ready to redeploy cash when the opportunity set improves, particularly as the Fed's policy path becomes clearer.
