Securitization in Focus — March 2026

Douglas Gimple

Headlines

Negative equity hits record levels

  • More trade-ins are coming in underwater — borrowers owe more on their auto loan than the vehicle is worth (negative equity).
  • J.D. Power estimates 30.5% of buyers with a trade-in are underwater, up 4.2% year over year and rising since 2022. A partial offset: the level remains below the 2019 pre-pandemic high of 33.6%.
  • The average negative-equity balance is about $7,200, a record high. Edmunds reports 27% of underwater trade-ins carry $10,000+ in negative equity — also a record.
  • The key impact is payment pressure: negative equity is often rolled into the new loan, increasing the financed balance. Edmunds estimates buyers who rolled negative equity paid an average of $916 per month in Q4 2025, a record and $144 above the average payment on all new-car purchases.
  • Higher vehicle prices reinforce the cycle. With the average new-vehicle price near $50,000 (about 30% higher than February 2020), borrowers are extending loan terms — raising the likelihood that depreciation outpaces amortization.

Government-sponsored enterprise purchases rise, but 30Y mortgage rates move higher (%)

mortgage rates
  • Fannie Mae and Freddie Mac increased their mortgage holdings by $10.6B in February, up from $7.0B in January. Relative to the administration’s early-January request for roughly $200B of purchases, the pickup from January to February was modest.
  • Mortgage rates initially drifted lower after the purchase announcement, bottoming near 6.10% in early March (Bankrate 30Y index). As Middle East conflict-related inflation concerns intensified, rates rose to about 6.50% late-month before easing slightly to 6.48% by March-end.

Geopolitical risk pushes spreads wider (bps)

spreads

Geopolitical uncertainty has contributed to wider spreads — the additional yield investors demand over Treasurys — amid concerns about commodity pricing, inflation and broader risk sentiment. Bloomberg index spreads across sectors illustrate the move since the conflict began.

Asset-backed securities

Geopolitical uncertainty and concerns about a prolonged Middle East conflict — particularly its implications for commodity prices and inflation — cooled issuance after the strong start to the year. March Asset-backed securities (ABS) issuance totaled $24.9B, the lowest monthly volume since the April 2025 “Liberation Day”-driven slowdown ($11.5B), excluding the seasonally slow December period. Credit-card ABS returned after a two-month pause tied to volatility around the proposed 10% APR cap, with Synchrony bringing a $500MM deal in mid-March. Auto ABS remained the largest contributor, representing 40.3% of March issuance.

Commercial mortgage-backed securities

Market uncertainty weighed on new issuance in non-agency commercial mortgage-backed securities (CMBS), mirroring the ABS slowdown. March issuance totaled just under $7.0B, down from January ($15.4B) and February (now updated to $17.4 B1). For Q1 2026, non-agency CMBS issuance reached $39.6B, below Q1 2025 ($45.8B) but more than double Q1 2024 ($19.4B).

1Month-to-month issuance totals can shift as transactions are reported and priced, contributing to differences vs previously reported figures (e.g., last month’s $9.2B estimate vs the updated $17.4B).

CMBS trends in March

New delinquencies concentrated: Of $5.1B in newly delinquent loans, five deals account for $2.0+B, pushing delinquency rates higher. Roughly 40% of newly delinquent loans were categorized as “performing matured balloon payment” last month — highlighting the ongoing cycle of loans maturing, turning delinquent, curing and then re-defaulting.

  • By property type: Four of five sectors moved higher.
    • Lodging: +137 basis points (bps) to 7.31%, rising above 7% for the first time since April last year.
    • Office: +51 bps to 11.71%, still elevated but below January’s 12.34% peak.
    • Retail: 6.30%6.62%, rebounding from February’s recent low.
    • Multifamily: up to 7.15%, above the prior peak of 7.12% (Oct 2025).
    • Industrial: 0.67%0.65%, the lone decline.
  • Overall: Delinquencies rose 41 bps to 7.55%, continuing the recent month-to-month back-and-forth pattern.

30+ Day CMBS Delinquencies (%)

Delinquencies
  • Year over year: Delinquencies increased 90 bps (6.65% → 7.55%).
  • Serious delinquency: Loans 60+ days delinquent, in foreclosure, real estate owned (REO) or non-performing rose to 7.29% (from 6.89%).

Residential mortgage-backed securities

Non-agency residential mortgage-backed securities (RMBS) issuance buckled neither to the ABS/CMBS slowdown nor to broader risk sentiment, totaling $18.5B in March — above February ($15.4B) and in line with January ($18.6B). Non-qualified mortgage (Non-QM) RMBS remained the largest segment, representing roughly 42% of issuance. Non-QM RMBS do not meet Consumer Financial Protection Bureau guidelines and allow more flexible eligibility and documentation. The “other” category — home-equity loans/lines and reverse mortgages — totaled $4.2B, up from February ($2.9B) and back near January’s pace ($5.0B).
