With the 2022 midterm elections less than two weeks away, a rapidly changing campaign season has analysts, investors, and citizens asking the same question: Who will control the House and Senate come November? General outlooks have been changing from month to month, but the potential for Democrats to maintain their majorities in both the House and Senate is growing increasingly difficult by the day, and history is certainly not on their side. Since World War II, the president’s party has lost House seats in 17 and Senate seats in 13 midterm elections, with an average of 27 seats lost in the House and three to four seats lost in the Senate. Going into this election, significant headwinds and substantial pre-election moves over the summer leave this race too close to call.

The state of the race

Early in the election cycle, redistricting as a result of the 2020 Census was viewed as providing a clear path for Republicans to gain a substantial majority in at least the House—especially when combined with a high number of Democrats retiring, low approval ratings for President Biden, and a perception that Democrats had failed to advance their legislative agenda.

Ultimately, however, redistricting provided Republicans with only a handful of pickup opportunities— enough to flip control of a narrowly divided House, but short of expectations. Over the summer, Democrats produced a string of legislative wins—including the CHIPS Act, bipartisan gun control legislation, and the Inflation Reduction Act. Paired with White House action on student loan forgiveness, these legislative wins appeared to energize the party’s base to vote this cycle—particularly younger voters who are less reliable in their resolve to show up to the polls. The Supreme Court ruling overturning Roe vs. Wade and subsequent trigger laws that went into effect in numerous states across the country further mobilized the Democrats’ base and female suburban voters. Overall, while President Biden’s approval rate remains at a historically challenging level, polling data shows a meaningful increase over recent months, moving from mid/high-30s to low/mid-40s—softening Democratic candidates’ need to outperform Biden’s numbers in various congressional districts and key states.

Going into this election, 35 seats are up for grabs in the Senate—21 held by Republicans and 14 by Democrats. All 435 House seats are up for reelection including the almost 30 Democrats not seeking reelection this year (Exhibit 1). Despite claims by Democrats that they see a path to retaining their majority in the House, forecasts suggest the House will flip to Republican control. A more pressing question regarding the House seems to be whether Republicans emerge with a governing majority or a fractured conference. The Senate, however, remains a virtual coin toss at this point with missed opportunities present on both sides. According to data from FiveThirtyEight as of October 26, Republicans have an 81% chance of gaining control of the House, and Democrats have a 54% chance of controlling the Senate. Although most see a divided government as the most likely outcome, nothing is guaranteed until the polls close.

Potential market impacts

So, what does this all mean for the markets? If history tells us anything, midterm elections have very little impact on market performance.

The correlation between stock market performance and midterm elections is well-documented. In 17 of the 19 midterms since 1946, the market performed better in the six months following an election than it did in the six months leading up to it—up on average 6% at three months and 11% at six months. However, this positive market reaction is most often a result of resolved uncertainty rather than a response to any specific policy agenda or election outcome. In short, the new makeup of the government does not have a statistically significant impact on market returns.

Bloomberg, Principal Asset Management. Assumes being wholly in or out of the market based on political control. Data as of October 13, 2022. Note: A Republican controlled government had a lower average return over the analysis period, but this was skewed significantly lower by the Great Depression period. The median return, on the other hand, was meaningfully higher.

Both unified and divided governments typically don’t have strong impacts on S&P 500 returns. Republican-controlled governments have a lower average return due to the great depression periods, but it’s not statistically significant (Exhibit 3). Ultimately, there are bigger market issues to consider going into 2023.

Structural policy decisions to watch in 2023

Rather than allowing political uncertainty to dictate investment decisions, investors should focus on the economics that will be responsible for market returns in the periods ahead. We have identified three key structural policy decisions to watch in 2023:

  • Unites States/China relationship: It would be a mistake for investors to view the CHIPS Act as the end of the legislative process on Capitol Hill regarding China as a strategic competitor. Bipartisan political pressure continues to mount in Washington for the creation of a national security review mechanism for U.S. outbound investment to China. Debate in Congress has focused on attaching a proposal to the annual National Defense Authorization Act or pursuing standalone legislation in 2023. The Biden Administration has even established an interagency working group contemplating an executive order to establish a review process. The outbound investment provisions seem largely focused on the tech industry, however an impact to additional industries cannot be ruled out.
  • The debt ceiling: Should Republicans win back control of either congressional chamber, a vote to raise the debt ceiling will likely be leveraged to extract spending cuts (potentially around entitlement programs) during negotiations with the White House. President Biden has publicly stated he would not support any effort to eliminate the debt ceiling entirely, calling it “irresponsible.” Debt ceiling discussions likely won’t materialize until the third quarter of 2023.
  • Fiscal stimulus: Despite the election’s outcome, Congressional leaders’ hands will be tied by the economic background given ever-present inflation and growth fears. As recently witnessed in the United Kingdom, where the government temporarily announced unfunded tax cuts, any additional fiscal stimulus announced in the U.S. would add to inflationary concerns and potentially result in significant market upheaval. Conversely, fiscal tightening would add to recession concerns. As such, a status quo in policy is the most likely result of the midterm election.

Tune out the political noise

For the past decade, easy financial conditions driven by historically accommodative monetary policy and ample liquidity have significantly supported markets. The 2022 midterm elections, however, are coming at a time in which American citizens are facing an onslaught of struggles including rising interest rates, elevated inflation, and the looming potential of recession. While there may be elevated volatility around the election, the outcome is unlikely to have a meaningful bearing on investment portfolios over the long term. Investors should focus on the economics that will be responsible for market returns in the periods ahead and tune out the political noise.
