Nathan Shetty, Chief Investment Officer at SEI, discusses the evolving role of alternative investments, which have been de-emphasized by the media and financial planners due to the success of traditional equities. Shetty notes that sticky inflation and unpredictable interest rates are shifting the way alternatives can serve portfolios now, and says the focus should be on complementing equity strategies, mitigating risk and achieving true diversification. Shetty, who oversees the team that manages the SEI Alternative Income fund, says he is “not anti-A.I., but pro-productivity,” looking past the A.I. eco-system to the businesses that benefit from the evolving technology. He also foresees some challenges ahead for credit markets, but does not think they will be disruptive to markets in the near term.

NATHAN SHETTY
Chuck, nice to be here.
CHUCK JAFFE
Let’s first talk about these market conditions. I should point out you’re coming back on The Navigator. You were here because you used to work at Nuveen, where you were the former head of multi-asset, and you’ve taken the approach as Chief Investment Officer at SEI, where you guys are still alternative managers, et cetera. But that means you’re looking at all the conditions, and we’ve got really interesting conditions right now. So help us understand: this market, which has gotten us back to equities being at record highs, there seems to be less focus on alternatives right now than there was just a year or so ago in terms of what the media is doing. But you’re always focused on alternatives. So what is this market setting up for you right now, and what is it guiding you towards as sweet spots?
NATHAN SHETTY
I love the question, Chuck, largely because it helps differentiate in the past why, whether they’re institutional or wealth managers, why they were approaching the alternative space. And I would say a decade or two ago, it was because they were trying to enhance returns. This was the low return environment, financial repression, interest rates were incredibly low. Expected real returns across traditional asset classes were abysmal at best. I’ll say in today’s environment, real expected returns, nominal expected returns, all look a lot more attractive. So now the question is, why would we incorporate alternatives? And to your point, the mass media is probably not as focused on it because traditional markets are raging. And I’ll say it’s largely now in the realm of risk mitigation and diversification. It’s been clear since 2022 that bonds aren’t a ballast. Mainly, sovereign rates are not a ballast to multi-asset portfolios, which then begs the question: If I’m going to have and run a diversified, truly as opposed to pseudo-diversified, portfolio, where might I look? And that’s really where alternatives come in: ultimately, how do I complement my growth exposures, i.e. equities, with something that’s actually truly diversifying? And that’s really where our efforts in alts are focused these days.
CHUCK JAFFE
In terms of that focus, are you going to different instruments? Because if you take a look at this market and this economy, you’ve got sticky inflation, you’ve got higher interest rates, at least on the short term, but actually on the long term as well, if we’re looking at Treasuries and what’s been happening there. So is that pushing you in different directions?
NATHAN SHETTY
Absolutely, and we are believers that inflation is here to stay and is likely starting to resume moving upward. Now, I can come on to the rationale and where that inflation is coming from. There are some short-term drivers that are both supply side as well as demand side related. On the supply side, clearly commodities and the energy shock is a contributing factor. But on the demand side, real growth is looking really impressive, as is nominal growth, which incorporates inflation as well. The capex investment, AI, I mean, it’s really red hot, and the two coincide with one another. On the long term, you’ve got deglobalization, demographics, deficits. Those are all contributing factors to inflation. This is putting a lot of pressure on short-term and long-term interest rates, and we think, again, this is a return to normal. While the backup has been incredible, this isn’t out of the realm of normalcy. So now, with bonds backing up in this manner, we have to understand and recognize what sorts of alternative investments might be at risk from duration. I mean, alts is a pretty broad category. There’s a whole host of exposures and instruments that we’re digging into, because we care more not about the label, but about the economic exposure it’s bringing to a multi-asset portfolio, and we don’t want risk on rates duration. Let me give you an example: real estate, for example, by virtue of how it’s financed, tends to be a long-duration asset. Yeah, there’s a real component to it, but it tends to be a long-duration asset. It will succumb to a further backup in interest rates. Infrastructure, on the other hand, tends to be shorter duration and hedged to inflation. That seems like a very interesting and compelling place. Whether on the private side or public markets, infrastructure seems quite compelling with this backdrop and environment. And of course, aligning with this reflationary backdrop, commodities look quite interesting. Then we can go a level deeper and talk about alternative strategies, not just instruments and exposures, but how might we deploy strategies that align with this regime and this environment? And two come to mind. We run portfolios in both of these: discretionary global macro and trend-following strategies are both alternatives with long volatility profiles that can really complement a multi-asset portfolio and embed that diversification benefit. So there’s a lot to play with in the alt space, whether we’re talking about instruments or strategies, to incorporate them in a more meaningful way in multi-asset portfolios.
CHUCK JAFFE
Well, one of the things I believe SEI is known for is the Alternative Income Fund that I mentioned. That is, at least last time I looked, heavy on CLOs. And I’m curious, given the market conditions we have, where we’ve had this tremendous upside, and we’ve also seen rates changing, we haven’t seen interval issues where we’re looking at interval funds having too many problems of, you know, liquidity issues and people want to get their money out and all these other sorts of things. But we also haven’t seen all of the benefits of, like, hey, you’re locked in, you’re going to have to ride with this thing. Are we getting to a market environment where we’re going to be testing the mettle of interval funds, how they work, interval fund investors? Can they actually do this the right way? And also the instruments underlying it, because again, with that structure, you guys can take different risks, which CLOs and some of the things happening there would be.
NATHAN SHETTY
Yeah, that’s right. Chuck, appreciate the question. I think a few things here. One, the liquidity of an interval fund should be based on the liquidity of its least liquid asset that it holds, and I think sometimes that’s lost in translation. That’s an important aspect, and they do serve an important role. Second, I mean, we are long-standing. Fifteen years we’ve been running CLO, particularly CLO equity. We’re expert CLO investors. They serve an incredible role if thoughtfully built into multi-asset, multi-strategy portfolios. We don’t see credit risk really developing in a way that reflects some of the pressures that we have seen in the more wealth- or retail-oriented private structures, and the desire to redeem or exit, whether it’s concerns over valuations or wanting to retain additional liquidity, that’s not reflective of the fundamentals. We don’t think we’re entering some credit cycle where defaults are absolutely going to skyrocket. Now, what I will say is, it’s incredibly important for the active manager to understand the names and the quality that exist. There is no question that there are businesses, and there’s going to be CLO structures, that are going to succumb to, as we see it, this heightened and sustained level of higher interest rates. The reason being, if you financed your business with margins expecting all-in borrow costs of whatever, 5% or 6%, and now you’re at 10% or 12% or 15% in terms of your overall financing rate because your base rate has ratcheted up, less robust businesses with less robust balance sheets could come under significant pressure. So doing the work, doing the credit analysis, is going to be critical to avoiding some of the defaults. But we’re not seeing systemic risk embedded in the credit markets right now.
CHUCK JAFFE
OK, not much systemic risk, but we’ve got a market that is heightened in its sensitivities. And if what you described happens, we see some blowups in CLOs, that will have an industry impact, particularly in closed-end funds, where you start talking about discounts and what’s trading at what kind of sentiment. And because we haven’t had big default problems, even as we’ve watched interest rates rise and all the rest, it would be the first time in a while. So, when you’re calling for “we’re going to see some problems,” are we going to see problems that, even though you say it’s not systemic, it’s not going to take many to make the market freak out? Is a freakout coming?
NATHAN SHETTY
Obviously, I don’t know whether or not a freakout is coming. I don’t think anybody can actually forecast whether or not a freakout is coming, but the fundamentals point to an underpinning of growth that’s going to enable the music to continue to play, I would say. I think we saw an elevation in some default rates, and they’ve actually subsided again. We’ve actually gone through a bit of a blip in some credit concerns, and they have already abated. At some point in time, credit will face issues. At some point in time, risk assets will face issues. At some point in time, the capex cycle, which is absolutely on fire, will have to top off, and the growth that underpins all of this is going to subside. We just don’t see it in the near term.
CHUCK JAFFE
You know, you talk about the growth that’s underpinning everything. Obviously, as you are looking at some of the alternatives and some of the financing things, et cetera, you can pick industries, you can pick spaces that you want to be in. Right now, how close do you want to be to what’s happening in AI? Like, are you “let’s be doing the AI direct,” “let’s be AI-adjacent,” “let’s be AI infrastructure-supportive,” or all of it?
NATHAN SHETTY
Love the question, Chuck. I’ll say a key theme that we are looking toward is not anti-AI, but pro-productivity. And the way we’re thinking about this from a sectoral standpoint is that those companies, organizations, and sectors that have really built up the AI ecosystem, whether it’s the picks and shovels or the models, so the software, the hardware, are specifically geared to the AI ecosystem. They’ve had to spend the money in order to develop this technology and ensure the proliferation of this technology. What we would argue is that this is a global, sector-agnostic technology that can benefit margins and productivity, whether it’s in the healthcare space, even the energy space, services, goods space, you name it. There are potential benefits to the technology where many of those industries didn’t have to spend the capex. Of course, there’s an opex component to embedding the technology, but they didn’t have to spend the capex to get it going. They are likely to be beneficiaries of continued margin expansion vis-a-vis productivity enhancement, and prices should start to reflect that. So this is to say that it’s still an AI-themed trade. I mean, that is what is underpinning everything. But I think there are a multitude of sectors that aren’t directly in the ecosystem that stand to benefit, i.e. catch up, from a pricing standpoint.
CHUCK JAFFE
Nate, really interesting stuff. I wish we had a little more time to chat. We’ll just have to make time to have you back on The Navigator down the line. Thank you for joining me today.
