I'm Michael Zezas, Global Head of Fixed Income Research and Public Policy Strategy.Ariana Salvatore: And I'm Ariana Salvatore, U.S. Public Policy Strategist.Michael Zezas: Today we'll be talking about the outlook for U.S. public policy and its interaction with markets into 2026.It's Wednesday, December 17th at 10:30am in New York.So, Ariana, we published our year ahead outlook last month. And since then, you've been out there talking to clients about U.S. public policy, its interaction with markets, and how that plays into 2026. What sorts of topics are on investors' minds around this theme?Ariana Salvatore: So, the first thing I'd say is clients are definitely interested in our more bullish outlook, in particular for the U.S. equity market. And normally we would start these conversations by talking through the policy variables, right? Immigration, deregulation, fiscal, and trade policy. But I think now we're actually post peak uncertainty for those variables, and we're talking through how the policy choices that have been made interact with the outlook.So, in particular for the equity market, we do think that some of the upside actually is pretty isolated from the fact that we're post peak uncertainty on tariffs, for example. Consumer discretionary – the double upgrade that our strategists made in the outlook has very little to do with the policy backdrop, and more to do with fundamentals, and things like AI and the dollar tailwind and all of all those factors.So, I think that that's a key difference. I would say it's more about the implementation of these policy decisions rather than which direction is the policy going to go in.Michael Zezas: Picking up on that point about policy uncertainty, when we were having this conversation a year ago, right after the election, looking into 2025, the key policy variables that we were going to care about – trade, fiscal policy regulation – there was a really wide range of plausible outcomes there.With tariffs, for example, you could make a credible argument that they weren't going to increase at all. But you could also make a credible argument that the average effective tariff rate was going to go up to 50 or 60 percent. While the tariff story certainly isn't over going into 2026, it certainly feels like we've landed in a place that's more range bound. It's an average effective tariff rate that's four to five times higher than where we started the year, but not nearly as high as some of the projections would have. There's still some negotiation that's going on between the U.S. and China and ways in which that could temporarily escalate; and with some other geographies as well. But we think the equilibrium rate is roughly around where we're at right now.Fiscal policy is another area where the projections were that we were going to have anything from a very substantial deficit expansion. Tax cuts that wouldn't be offset in any meaningful way by spending cuts; to a fiscal contraction, which was going to be more focused on heavier spending cuts that would've more than offset any tax cuts. We landed somewhere in between. It seems like there's some modest stimulus in the pipe for next year. But again, that is baked. We don't expect Congress to do much more there.And in terms of regulation, listen, this is a little bit more difficult, but regulatory policy tends to move slowly. It's a bureaucratic process. We thought that some of it would start last year, but it would be in process and potentially hit next year and the year after. And that's kind of where we are.So, we more or less know how these variables have become something closer to constants, and to your point, Ariana now it's about observing how economic actors, companies, consumers react to those policy choices. And what that means for the economy next year.All that said, there's always the possibility that we could be wrong. So, going back to tariffs for a minute, what are you looking at that could change or influence trade policy in a way that investors either might not expect or just have to account for in a new way?Ariana Salvatore: So, I would say the clearest catalyst is the impending decision from the Supreme Court on the legality of the IEEPA tariffs. I think on that front, there are really two things to watch. The first is what President Trump does in response. Right now, there's an expectation that he will just replace the tariffs with other existing authorities, which I think probably should still be our base case. There's obviously a growing possibility, we think, that he actually takes a lighter touch on tariffs, given the concerns around affordability. And then the second thing I would say is on the refunds ...
