Empirical research confirms that merger and acquisition strategies (M&A), as represented by M&A index returns, are positively related to the interest rate and the change in interest rate. This positive relationship between M&A index returns and interest rates is driven less by the economic cycle, but by the unique nature of M&A deal risk.
Furthermore, given M&A’s low correlation to the equity and fixed income markets, it could serve as a diversified source of return and help investors manage volatility in a rising rate market.
In 2015 the Federal Reserve (“the Fed”) began raising interest rates after lowering them to historic lows as a result of the economic fallout of the 2008 Great Financial Crisis. From 2015 to 2019, the Fed Fund Target Rate was raised nine times to as high as 2.5% until the onset of the COVID-19 Pandemic in 2020 forced a reverse in course. Although the Fed has committed to supportive monetary policies as we navigate the recovery from the pandemic, we have already seen inflation expectations picking up and investors questioning when interest rates will begin to go up again.
Historically, when interest rates have climbed, fixed-income returns have generally fallen. With rates unlikely to remain low indefinitely, how should investors respond? Is there anything they can do to mitigate the fixed-income losses that are likely to occur in this environment?
Capitalizing on deal risk
One possible strategy is merger arbitrage. This alternative investment seeks to profit from the price increase that often occurs in the stock of a company being acquired. When an acquisition is announced, that stock typically rallies but usually remains below the takeover bid. This “discount” represents “deal risk,” the possibility that the transaction will fail due to financing difficulties, regulatory issues, problems obtaining shareholder approval, or other factors. As the deal moves closer to consummation, this spread typically narrows as the risk dissipates.
One advantage of taking on this risk is its diversification benefit. That is, because deal risk is modestly to negatively correlated to conventional asset classes, adding a merger arbitrage strategy to a portfolio may provide added diversification of risk.
M&A and interest rates
How have merger arbitrage strategies performed historically? Chart 1 shows that merger arbitrage index returns have been better when interest rates have been higher. For example, when the “risk-free” interest rate was 3.5%-4.0%, the average 12-month index return on merger arb strategies was 6.84%. This is in line with the index returns these strategies have typically sought, that is, 3%-6% over the risk-free rate.
Chart 2 illustrates how merger arb index returns have, until recently, tracked closely with the risk-free rate. Two features are immediately evident: 1) Prior to late 2008, the correlation between a rising, risk-free rate and merger arbitrage index returns was very tight, and 2) after 2008, that correlation weakened.
For example, in late 2000, index returns began to decline and continued to do so as short-term interest rates plummeted over the next two years. On the other hand, merger arbitrage index returns improved as short-term interest rates rose sharply between 2004 and 2007.
It’s also noteworthy that the link between the risk-free rate and the merger arb index returns was broken beginning in 2008. No doubt, the extraordinarily low-interest rates maintained by the Fed over the past ten years have been a key driver behind lower merger arb index returns, suggesting that when rates trend toward normal levels, index returns will trend higher as well.
High and rising interest rates drive merger arb index returns
To better understand the performance of merger arb strategies, we examined index returns between December 1994 and December 2020, analyzing them in relation to three factors:
- the risk-free rate at the start of the year,
- the change in the risk-free rate over one year, and
- economic conditions at the start of the year, represented by the Conference Board’s Coincident Index
of Economic Indicators, which tracks non-farm payrolls, personal income, industrial production, and
sales by the manufacturing, wholesale, and retail sectors.
We found that both high rates and rising rates helped to account for a significant portion of the variability of index returns over this period. Broader macroeconomic conditions, on the other hand, did not.
To be more specific, a one-percentage-point increase in the starting risk-free rate was associated with a rise of 1.97 percentage points in merger arb index returns (see Table 2). Similarly, a one-percentage-point increase in the rate of change in the risk-free rate was associated with an improvement of 1.89 percentage points. On the other hand, general economic conditions had little effect on index returns. Although the effect of this factor was statistically significant, it was so small as to be meaningless.
Moreover, our analysis showed that, on average, merger arb strategies produced an alpha of 1.70% per year relative to these factors. One way to interpret this is that it represents the deal risk we noted earlier, or the index return captured when the target company’s stock rallies during the period between the deal announcement and the closing.
This finding, that merger arb performance tracks with short-term interest rates and changes in those rates, may seem counterintuitive. Low rates, in fact, are often cited as more conducive to merger and acquisition activity.
How interest rates account for merger arbitrage performance
So, why are high and rising rates associated with stronger merger arb index returns? We believe there are four reasons:
- Deal premium — With mergers and acquisitions, there is always a risk that a deal will fall through.
The expected return on merger arbitrage incorporates a premium above the risk-free rate that reflects
this risk. Therefore, adding this premium to the risk-free rate when that rate is rising results in a higher
- Opportunity cost — Merger arb strategies must offer attractive returns, or investors will opt for other
investments with comparable returns but less risk. With interest rates at high levels, investments
offering attractive returns with lower risk may be more plentiful. If merger arb returns fail to compensate
for deal risk sufficiently, investors will pull their money from arb funds and opt for these other investments.
- Borrowing cost — As interest rates rise, the acquiring company requires a bigger deal premium
because if it is financing the deal with debt, its borrowing costs will be higher. The acquiring company
will capture this premium via a lower purchase price, producing higher returns for merger-arb investors.
- Higher return on collateral — Most arbitrage strategies employ some type of a short position to
help manage downside risk. Whether the short is at the market or sector level or is a short on the
stock of the acquirer, the lender will require that cash be put aside as collateral on the short. As
rates rise, the cash return on the collateral will also rise, providing a positive return potential when
interest rates rise.
The bottom line for investors? As we recover from the pandemic, interest rates would not stay at these historic lows forever. And if history is any guide, higher rates could result in attractive return potential for merger arbitrage strategies, making this alternative investment a timely complement to a fixed-income portfolio. Moreover, because this strategy is uncorrelated with traditional asset classes, it may also provide additional diversification benefits.

Merger arbitrage risk is the principal risk associated with the Fund’s investments, in that certain of the proposed takeover transactions in which the Fund invests may be renegotiated, terminated, or involve a longer time frame than originally contemplated, for business reasons or due to regulatory oversight or for other reasons, which, in each case, may negatively impact the Fund’s returns.
Short positions, including short exposure to securities indexes, introduce more risk to the Fund than long positions (purchases) because the maximum sustainable loss on a security purchased (held long) is limited to the amount paid for the security plus the transaction costs, whereas there is no maximum attainable price of the shorted security. Therefore, in theory, securities sold short, have unlimited downside potential.
