Fixed Income Leaders Summit 2026: Key Takeaways for SMA Managers

The Fixed Income Leaders Summit wrapped up in Boston this week, pulling more than a thousand buy-side professionals into the Westin Copley Place. The city had a second crowd in town too, with the Tartan Army descending on Boston for the World Cup, and when fixed income leaders and the Tartan Army collide, the energy in the city is hard to miss. The city had a second crowd in town too, with the Tartan Army descending on Boston for the World Cup, and when fixed income leaders and the Tartan Army collide, the energy in the city is hard to miss. Strip away the macro outlooks and the rate debates, and the conversations that mattered most were not really about markets in the abstract. They were about the machinery underneath the desk: how portfolios get built, how trades actually get done, and how teams keep up as the book grows.

If you run separately managed accounts as a portfolio manager or CIO, that framing should feel familiar. The pressures the agenda surfaced are the same ones that greet you every morning on a desk juggling hundreds of customized accounts. Here are three signals worth carrying into the rest of the year.

1. SMA growth has moved from a side business to the main event

The agenda put the rise of SMAs, private credit, and ETFs right at the center of the portfolio construction conversation, and the numbers explain why. Assets in separately managed accounts are projected to reach roughly $3.6 trillion in 2026, up from about $2.2 trillion in 2023, according to Cerulli Associates. Fixed income SMAs are now the fastest-growing vehicle in the asset class. Industry data puts their compound annual growth rate near 29 percent from 2020 to 2024, while the broader fixed income market grew at about 7 percent.

That kind of growth is good news and a stress test at the same time. Every new SMA carries its own client guidelines, restrictions, and strategy, and honoring all of them across a growing book is exactly where manual, spreadsheet-bound workflows start to crack. The firms that pull ahead will be the ones that can construct and customize portfolios at scale without adding a head for every new account. Growth in the book should not have to mean adding headcount anywhere.

2. Liquidity is fragmented, and connectivity is the way through

One challenge ran through the whole event: fragmented liquidity. Credit markets are still organized around a series of largely siloed ecosystems, and the long-promised electronification of less liquid corners remains uneven. Desks are working across more venues, more data feeds, and more protocols than ever. Stitching that picture together by hand is slow, and it is easy to get wrong.

This is where the real cost of disconnected systems shows up. When a manager has to export to a spreadsheet just to compare options or pull insight from another platform, the analysis ends up living away from the system of record, and the edge quietly erodes. So the move most desks are reaching for is consolidation: bring the inputs into one connected hub, and let the team spend its time deciding instead of reconciling. No single firm can fix fragmentation in the market. Fragmentation in your own stack is another story.

3. Compliance is the constraint that scales the fastest

For all the talk about growth and automation, the quietest theme on the floor was the one that keeps PMs up at night: proving every trade is clean, on every account, every time. Each SMA comes with its own guidelines, restrictions, and tax considerations, and the obligation does not soften as the book grows. It compounds. A desk running fifty accounts can reason its way through exceptions by hand. A desk running several hundred cannot, and the manual check that worked at the smaller number becomes the thing standing between the team and the next stage of growth.

The hidden cost is not only the trade that should have been blocked. It is the hours spent reconstructing what happened after the fact, the audit that takes a week instead of an afternoon, and the client conversation you never want to have. Compliance that is bolted on after the decision will always lag the book. Compliance that sits in front of the trade, configured to each account’s rules and checked before anything executes, is what lets a team add accounts without adding risk. A guideline you cannot enforce at scale is not a standard. It is a hope.

4. Everyone is talking about AI. Almost no one is using it properly

AI and machine learning were everywhere on the agenda, and that is precisely the problem. The talk has raced way out ahead of the doing. For all the panels and predictions, the number of desks actually getting real, repeatable value out of AI is a lot smaller than the volume of conversation would suggest. The interesting questions have already moved past whether AI matters and on to where it actually earns its keep: smarter execution that weighs liquidity and venue in real time, automated rebalancing, fewer repetitive manual steps across the trade lifecycle.

Here is the part that gets glossed over in the hype. AI bolted onto a broken or manual foundation does not deliver much, and no model fixes a workflow that still runs through a dozen spreadsheets. Automation pays off when it sits on clean, connected data and well-structured workflows, which is why the modernization conversation and the AI conversation turn out to be the same conversation. The winners will not be the firms talking about AI the most. They will be the ones who built the foundation that lets it work.

The through-line: customization at scale

Pull these four signals together and they all point the same way. The fixed income business is getting more customized, more connected, more automated, and more closely scrutinized, all at once, and the common requirement is the ability to do every bit of it across many accounts without the work multiplying account by account.

That is the gap worth sitting with. The growth a firm is planning for and the operating model meant to absorb it are rarely on the same trajectory, and the distance between them is where good desks quietly stall. IMTC delivers the operational infrastructure and intelligence fixed income managers need to optimize across accounts, execute with precision, and scale with confidence.

So the question to carry out of Boston is a simple one. Can your current operating model absorb the growth you are planning for, or will it quietly cap it? That is a better question to answer before the growth arrives than after.
