In the final Convexity Pulse episode of 2025, Kirill Krylov and Steven Scheerer explore three themes shaping the 2026 MBS outlook: the quiet return of GSE buying, the growing policy debate around whether Fannie and Freddie should support construction lending, and the steady role of money managers as the market’s center of gravity. They discuss how recent FHFA actions have reopened retained portfolio capacity, why AD&C lending remains controversial despite supply shortages, and how passive and active fund flows continue to anchor MBS demand. The episode closes with a forward-looking assessment of where spreads may settle as banks, GSEs, and money managers each play distinct roles in next year’s market.

Kirill Krylov and Steven Scheerer break down one of the biggest structural developments in years: Freddie Mac’s new Loan Level Directed Collateral platform and how it reshapes the design of REMIC collateral from the ground up. They explain how LLDC allows dealers to deconstruct pools and rebuild pseudopools at the loan level to target specific credit, seasoning, geographic, and convexity features that had never been selectable before. The episode then turns to the outlook for bank demand in 2026, highlighting why deposit growth, a steeper curve, regulatory shifts, and relative value could draw banks back into MBS in meaningful size.

In this post-Thanksgiving special edition of the Convexity Pulse, Kirill Krylov is serving up the 2026 Agency MBS outlook that the team has been preparing alongside our holiday roasts. He breaks down the expected rise in gross mortgage supply, the restrained path for net supply, and the broadening demand picture across GSEs, banks, REITs, ETFs, and asset managers. Taken together, these forces point to an optimistic outlook for the mortgage basis next year. The episode wraps with a look at the 2026 housing market, highlighting modest home price gains, cooling rates, and a gradually improving but still affordability-constrained environment.

This week on the Convexity Pulse, Kirill Krylov and Steven Scheerer break down the shift from equity outflows into fixed-income inflows and what that means for MBS performance heading into year-end. They explore the “silver wave” of seniors carrying mortgage debt into retirement and how this creates welcome increases to prepayment speeds in discount cohorts. The episode closes with a look at assumable and portable mortgage proposals, examining how each idea could reshape prepay behavior, credit exposure, and pricing across the MBS market.

This week's Convexity Pulse finds Kirill Krylov and Steven Scheerer tackling three big mortgage market shifts: the rising talk of a 50-year mortgage, potential upcoming LLPA changes, and the debut of VantageScore 4.0 in agency MBS. They explore how credit scoring reforms and aging borrower demographics could reshape cash-out refi behavior, prepayment models, and MBS convexity. The conversation also highlights why extending loan terms might mask affordability problems rather than solve them.

Kirill and Steven break down the surge in October prepayments and what it means for November’s setup. They analyze the GSEs’ meaningful portfolio expansion, with Fannie and Freddie adding more than $33 billion in the third quarter and discuss how further GSE demand could help stabilize spreads and liquidity. The episode closes with a look at early signs of renewed bank demand for MBS heading into 2026, as capital rules, rate cuts, and deposit growth start aligning for a potential re-entry.

This week on the Convexity Pulse, Kirill Krylov flies solo for a recap that spans gold’s sharp reversal, shifting fund flows, and REITs’ growing influence in the mortgage market. He unpacks the divergence between active and passive inflows, and the renewed buying power of leveraged REITs. He ends with thoughts on Bloomberg’s proposal to reintroduce Ginnie Mae custom pools into the Aggregate Index and how that could reshape MBS weights and convexity risk.

This week on the Convexity Pulse, Kirill Krylov and Steven Scheerer recap a “pre-Halloween rally” in Treasuries as softer inflation and fresh Russia sanctions push yields below 4%. They discuss the approaching end of Quantitative Tightening, a growing call for GSEs to re-enter the MBS market, and how that could reshape spreads and affordability. The duo closes with a deep dive into relative-value trades across the belly and premium coupons, revealing where convexity still hides in plain sight from inefficient Loan Balance 4.5s to high-DTI Mission 5.5s. 

This week on the Convexity Pulse, Kirill Krylov and Steven Scheerer widen the lens, tackling how the government shutdown’s data blackout is distorting market visibility and mortgage valuations. They explore the global “gold rush” as central banks swap Treasuries for bullion, the potential long-term impact of the Senate’s ROAD to Housing Act on affordability and Ginnie supply, and finish with a technical dive into the paradoxical behavior of Quicken low-loan-balance pools, the MBS trade investors love to hate but can’t ignore.

This week’s Convexity Pulse finds Kirill Krylov flying solo as he navigates a data blackout caused by the government shutdown, renewed U.S. / China trade tensions, and a market rally built more on uncertainty than conviction. He explores how missing data clouds mortgage modeling, reviews Bloomberg’s new weighted loan count feature for Supers, and connects America’s falling birth rate to the long-term housing pipeline. Kirill also dives into Florida’s cooling housing market and rising prepayment activity driven by AI-assisted loan processing.
