Welcome to Thoughts on the Market. I'm Michael Zezas, Morgan Stanley's Global Head of Fixed Income and Thematic Research. Along with my colleagues bringing you a variety of perspectives, today I'll be talking about the US elections and its impact on markets.

It's Tuesday, July 2nd at 10:30am in New York. 

For months, investors have been asking us when markets will start paying attention to the US presidential election. Well, we think that time arrived with last week’s Presidential debate. 

The media coverage that followed revealed that many Democratic party officials became concerned about President Biden’s ability to win the November election. This understandably led many to ask if the race for the White House had meaningfully changed; If it was no longer a close one – and if so, what would that mean for markets that might have to start pricing in the impacts of a Trump Presidency. 

On the first question: While we think it's too early to conclude that the race is no longer a close one, we expect some data in the next week or two that could clarify this. The few polls that have been released following the debate show that voters are increasingly concerned about Biden’s ability to win; but they also show a level of support for Biden similar to what he enjoyed before the debates. 

What we haven’t seen yet is a set of high-quality polls gauging swing state voter preferences. And even modest deterioration in Biden’s support there could meaningfully boost Trump’s prospects. That’s because, going into the debate, polls showed former President Trump with a small but consistent lead in national and key swing state polls. 

Nothing outside the polling margin of error. But it still suggested that for President Biden to improve his odds of winning, he’d be served well by having a strong debate performance that moved the polls more in his favor.  

It doesn’t appear that this has happened, and if polls show movement in the other direction for Biden, it would be fair to think of Trump as something of a favorite. But only for the time being. There’d still be time and catalysts for the race to change – including another scheduled debate in September. 

If we do end up with a race where Former President Trump is a more clear favorite, even if just for a short time, there could be reflections in the market. As we’ve previously discussed, a Trump win increases the chances of more of the expiring tax cuts being extended. The benefits of those cuts most clearly accrue to key sectors like energy and telecom, so there’s potential outperformance there.  

In fixed-income – a steeper US Treasury yield curve is an outcome our macro strategy team is particularly attuned to. That’s because a Trump presidency brings greater uncertainty about future fiscal policy, which could be reflected in relatively higher yields for longer maturity bonds. But it also increases the chances of policy choices that create near term pressure on economic growth that could push shorter maturity yields lower. This includes higher tariffs and tighter immigration policies. 

So bottom line, the markets are paying attention. And the race is sure to have many more twists and turns. We’ll keep you updated on how we’re navigating it.
