I'm Andrew Sheets, Head of Corporate Credit Research at Morgan Stanley. Lisa Shalett: And I'm Lisa Shalett, Chief Investment Officer for Morgan Stanley Wealth Management. Andrew Sheets: Today, is inflation really transitory or are we entering a new era where higher prices are the norm? Andrew Sheets: It's Thursday, December 18th at 4pm in London. Lisa Shalett: And it's 11am in New York. Andrew Sheets: Lisa, it's great to talk to you again. And, you know, we're having this conversation in the aftermath of, kind of, an unusual dynamic in markets when it comes to inflation. Because inflation is still hovering around 3 percent. That's well above the Federal Reserve’s 2 percent target. And yet the Federal Reserve recently lowered interest rates again. Fiscal policy remains very stimulative, and I think there's this real question around whether inflation will moderate? Or whether we're going to see inflation be higher for longer. And you know, you are out with a new report touching on some of the issues behind this and why this might be a structural shift higher in inflation. So, we'd love to get your thoughts on that, and we'll drill down into the various drivers as this conversation goes on. Lisa Shalett: Thanks Andrew. And look, I think as we take a step back, and the reason we're calling this a regime change is because we see factors for inflation coming from both the demand side and the supply side. For example, on the demand side, the role of the infrastructure boom, the GenAI infrastructure boom, has become global. It has caused material appreciation of many commodities in 2025. We're seeing it obviously in some of the dynamics around precious metals. But we're also seeing it in industrial metals. Things like copper, things like nickel. We're also seeing demand factors that may stem from the K-shaped economy. And the K-shaped economy, as we know, is really about this idea that the wealthiest folks are increasingly dominating consumption. And they are getting wealthy through financial asset inflation. On the supply side, there are dynamics like immigration, dynamics around the housing market that we can talk about. But perhaps the wrapper around all of it is how policy is shifting – because increasingly policymakers are being constrained by very high levels of debt and deficits. And determining how to fund those debts and deficits actually removes some of the degrees of freedom that central bankers may have when it comes to actually using interest rates to constrain demand. Andrew Sheets: Well, Lisa, this is such a great point because we're financial analysts. We're not political analysts. But it seems safe to say that voters really don't like inflation. But they also don't like some of the policies that would traditionally be assigned to fight inflation – be they higher interest rates or tighter fiscal policy. And even some of the more recent political shifts that we've seen – I’m talking about the U.S. around, say, immigration policy could arguably be further tightening of that supply side of the economy – measures designed to raise wages, almost explicitly in their policy goals. So how do you see that dynamic? And, again, kind of where does that leave, you think, policy going forward? Lisa Shalett: Yeah. I think the very short answer – our best guess is that policy becomes constrained. So, on the monetary side, we're already seeing the Fed beginning to signal that perhaps they're going to rely on other tools in the toolkit. And what are those tools in the toolkit? Well, they're managing the size of their balance sheet, managing the duration or the mix of things that they hold in the balance sheet. And it's actual, you know, returns to how they think about reserve management in the banking system. All of those things, all of those constraints may enable the U.S. government to fund debts, right? By buying the Treasury bill issuance, which is, you know, swollen to almost [$]2 trillion a year in terms of U.S. deficits. But on the fiscal side, right, the interest payments on debt, begins to crowd out other government spending. So, policy itself in this era of fiscal dominance becomes constrained – both in, you know, Washington, D.C. and from Congress – what they can do, their degrees of freedom – and what the central bank can do to actually control inflation. Andrew Sheets: Another area that you touch on in your report is energy and technology, which are obviously related with this large boom that we're seeing – and continue to expect in AI data center construction. This is a lot of spending on the technology...
