Episode Overview

In this episode, Ariana Salvatore delves into the latest U.S. trade policy headlines, unpacking what proposed tariffs and ongoing USMCA negotiations could mean for investors. She explains that, while these developments might seem like an escalation, they largely reflect a continuation of the current regime rather than a pivot to more severe trade restrictions. The discussion centers on Section 301 tariffs, the future of the USMCA, and the broader implications for markets and the economy—particularly in the lead-up to the midterm elections.

Key Discussion Points & Insights

1. Context: New Tariffs and Trade Policy Moves

• Section 301 Investigations:
  • The U.S. Administration is proposing new tariffs following Section 301 investigations into over 60 trading partners.
  • Ariana frames this not as a major escalation, but as a step to preserve the existing tariff regime, substituting expired authorities post-Supreme Court decision.
  • "We think these headlines are best understood as a continuation of the existing tariff regime rather than a new and more disruptive phase." (Ariana, 00:40)
• Transition from Section 122:
  • The IIPA tariffs were replaced by Section 122 under a temporary authority post-Supreme Court, which expires in July.
  • The administration is expected to seek new authority to preserve the current policy, with Section 301 being the mechanism.
  • "The conclusion of the Section 301 investigations is really a step in that direction, or said differently, a continuation of existing policy." (Ariana, 01:30)

2. USMCA Negotiations and Trade Alignment

• Regional Content Rules:
  • Active negotiations could see raised regional content requirements for vehicles and auto parts, potentially creating sector-level friction.
  • However, Ariana believes structural and procedural constraints—plus the value of North American supply chain integration—will limit downside risks.
  • "We still expect the USMCA carve out to remain in place even for Section 301 goods on a range of trading partners." (Ariana, 02:20)
• Potential for Escalation:
  • Some friction is possible ahead of the July deadline, but a wholesale withdrawal from the agreement is unlikely.

3. Tariff Policy Trends and Administrative Sensitivities

• Decreasing Trade Pressure:
  • Despite headline risks, the trend in recent months has been toward less trade pressure, with several carve outs, exemptions, and delays.
  • "That suggests that the administration is still sensitive to the downstream cost impact of tariffs. And of course, affordability matters politically heading into the midterm elections." (Ariana, 02:50)

4. Economic and Market Implications

• Macro Backdrop:
  • U.S. economic growth is expected to remain steady; consumer spending is slowing but not collapsing.
  • AI-driven capital expenditures and resilient corporate earnings are offsetting some drag from policy uncertainty and higher energy prices.
  • "Growth is expected to remain trend like with consumer spending slowing but not collapsing and strong AI led capex offsetting some of the drag from higher energy prices and policy uncertainty on inflation." (Ariana, 03:10)
• Investor Takeaway:
  • Tariff policy remains "noisy" and will continue to generate headline risk, but the base case is stability, with no major market disruption expected.
  • "The key message for investors is this: tariff policy is still noisy and it will remain a source of headline risk. But... the administration is moving toward a more durable version of the current tariff regime, not a materially more disruptive or restrictive one." (Ariana, 03:40)

Summary

This episode offers a measured perspective on the latest tariff developments and their macro and market implications. Ariana Salvatore argues that while tariffs remain a risk, current headlines reflect mostly a continuation of existing policy, not a turn toward disruption. Sector-specific frictions and politicized trade moves may cause volatility, but the outlook for the U.S. economy and markets is supported by structural growth trends, especially in AI and corporate earnings. Investors should be alert to headlines but not overreact to apparent escalation in tariffs or trade disputes.

Transcript

[A]

Welcome to Thoughts on the Market. I'm Ariana Salvatore, head of Public Policy research for Morgan Stanley. Today I'll be talking about how investors should be digesting the latest tariff headlines and what they could mean for the broader economic and market outlook. It's Friday, June 5th at 10:00am in New York. Tariffs are back in focus as the US administration has proposed new levies following Section 301 investigations into more than 60 of our trading partners. At the same time, USMCA negotiations appear to have begun in earnest with recent headlines focused on autos, including the possibility of raising regional content requirements for vehicles and auto parts. Now, at first glance, these developments sound like a meaningful escalation in trade policy, but we think these headlines are best understood as a continuation of the existing tariff regime rather than a new and more disruptive phase. Let's start with section 301. Listeners may recall that the Administration replaced the IIPA tariffs with section 122 following the Supreme Court's decision back in February. However, that was done under a temporary authority that expires in the end of July. It's been our view that as we approach that deadline, the Administration would seek to replace the existing regime under a new authority. The conclusion of the Section 301 investigations is really a step in that direction, or said differently, a continuation of existing policy. We see the administration preserving the current tariff regime come July, but without a larger inflation or growth shock. The second issue is the usmca. Raising regional content rules may be part of the negotiation now, and those changes could create sector level friction. Similarly, we think it's possible we see escalation ahead of the July deadline as all three countries work to improve the existing trade deal. Now, that being said, we're still constructive on the longer term trade alignment between the U.S. mexico and Canada, and we see structural and procedural constraints that are going to limit the downside risk to something like a potential withdrawal from the agreement. We still expect the USMCA carve out to remain in place even for Section 301 goods on a range of trading partners. That's because we think the administration sees value in maintaining supply chain integration within North America across a number of sectors. In general, we actually think the recent pattern on tariffs has been toward less, not more, trade pressure at the margin. Recent months have come with several carve outs, exemptions and delays on broad based and sectoral tariffs. That suggests that the administration is still sensitive to the downstream cost impact of tariffs. And of course, affordability matters politically heading into the midterm elections in November that view also fits with our broader US economics outlook. Our economists continue to see a relatively benign macro backdrop. Growth is expected to remain trend like with consumer spending slowing but not collapsing and strong AI led capex offsetting some of the drag from higher energy prices and policy uncertainty on inflation. Tariffs remain part of the story, but much of the pass through appears to be already in the data. That pairs with a more constructive outlook for equity markets as well. As our strategists there see a strong earnings story supported by things like positive operating leverage, AI adoption, improving pricing power and a broadening out in earnings growth. So the key message for investors is this tariff policy is still noisy and it will remain a source of headline risk. But in our base case, the administration is moving toward a more durable version of the current tariff regime, not a materially more disruptive or restrictive one. Section 301 replaces Section 122. The USMCA carve out stays in place and selective exemptions continue where the affordability or supply chain costs are too high. Thanks for listening.
