Welcome to Thoughts on the Market. I'm Michael Zezas, Global Head of Fixed Income and Thematic Research for Morgan Stanley. Along with my colleagues, bringing you a variety of perspectives, I'll be talking about the impact of presidential debates on markets. It's Wednesday, August 23rd at 10 a.m. in New York. 

Several candidates seeking the Republican Party's nomination for president take the stage in the debate tonight. Coverage of the event in traditional and financial media has escalated in anticipation of the debate. And while it's a good idea for voters looking to understand the candidates better and make an informed choice to tune in to the debate, for those tuning in looking for something that might guide their perception of how the 2024 election might impact financial markets, our guidance is this: lower your expectations. 

This debate, the first among many, is likely to tell us a lot less about who the nominee will be than traditional polls. Those polls show former President Trump with solid support that surpasses his main rivals. And while, of course, there's plenty of time for that to change, debates this early in the process haven't historically been reliable indicators of changes in support that may follow. This may be even more true this time around, since President Trump is not attending this debate. And so it will be more difficult to get a read as to which candidates might be better suited than others to make a more persuasive argument to Republican voters than the former president. 

Additionally, debates this early in the process generally tell us little about potential policy changes that could result from any one of these candidates ultimately being elected in 2024. Stock and corporate bond investors, in theory, might be very interested in what these candidates have to say about a variety of pending corporate tax code changes starting in 2025. But one shouldn't expect candidates to get into that level of detail on the debate stage. General comments about making sure the tax code doesn't work against the economy are far more likely. Further, the ability of any candidate to execute on their policy vision is going to be a function of the makeup of Congress, which again, this debate is unlikely to give us much information about. 

Bottom line, the 2024 election will be consequential to the markets, but tune in to the debate to inform yourself as a voter. As we've said in previous podcasts, it's too early to expect to learn anything that will help you as an investor.
