The one-way door.

Bottom line

The claim is one sentence. Credit unions are early in a shift from holding what they originate to distributing it, the shift is small in dollars and cyclical in its trigger, and it is one-directional in its structure, because every capability it has built outlives the conditions that built it.

Three things sit on the record. First, the deals: from GTE Financial's November 2019 debut through PenFed's fourth transaction in June 2026, the July 2025 Alloya multi-issuer trust, Corporate One's January 2026 multi-seller deal, and Lafayette Federal's February 2026 home-improvement transaction, the first credit union ABS on collateral other than autos. Second, the trigger: a liquidity swing that took the system loan-to-share ratio from a record-low 68.8% in early 2021 to above 81% by late 2022, on loan growth near 19%. Third, the fact that carries the forward argument: the trigger has eased and the behavior has not. By the first quarter of 2026, system net income was up 30.5% year over year and loan-to-share had fallen to 81.5%. Over the same stretch, the first half of 2026 produced roughly $1.4 billion, against $2.1 billion for all of 2025.

Read the shape rather than any single bar. One deal, then a year with none at all, then a slow build to a step change in 2023 that has held for three years and is already matched in the first half of 2026. The dollar row underneath is deliberately secondary. Sources disagree on annual dollars by as much as 25%, because they are counting different universes: KBRA and Dechert tally the market and land within a rounding error of each other, while S&P counts only what it rates and reports a smaller number for the same year. The deal count is where they converge, so the deal count carries the chart.

I · The first deal, and the roster since

GTE Financial is the right place to start, because GTE's own history contains the whole thesis in miniature.

Before it ever issued a bond, GTE distributed the old way. Its CFO, Brad Baker, has said the credit union sold roughly $202 million of auto loans through participations between 2014 and 2018, in individual pieces ranging from $1 million to $23 million. Participations were the ceiling of what a credit union could do with its own paper: private, bilateral sales to other depositories, funded by those depositories' deposits. Then in November 2019, GTE became the first credit union in the country to sponsor a securitization, pledging roughly 9,000 new- and used-car loans with a balance of $185.27 million as collateral for GTE Auto Receivables Trust 2019-1, a Rule 144A transaction through Stifel Nicolaus. Same institution, same collateral, a different instrument, and a different buyer base entirely.

Two different sizes circulate for that deal, and the capital structure settles it. The A classes were a $36.3 million money-market tranche, $58.19 million of A-2 and $52.94 million of A-3, which sum to $147.4 million. Add the $22.3 million single-A and $5.3 million BBB subordinates and total notes come to $175.0 million, against the $185.27 million pool. So $147.4 million is the senior classes, $175 million is total notes, and $185.27 million is collateral. Both circulating figures were right about different things. This brief uses $175 million, total notes.

Then nothing. GTE returned to market on April 24, 2023, with a $202.8 million deal, three and a half years after the first one, through the Stifel and BofA Securities program that ran four of that year's credit union transactions. The gap is the part worth sitting with. The pioneer did not become a habitual issuer on the strength of the experiment working. It waited out 2020, 2021 and 2022, and came back in the middle of the liquidity squeeze, in the same year six other credit unions priced deals. The tool had been legally available since the 2017 safe harbor, six years by then, and stayed largely unused until conditions made it necessary. Three and a half years is GTE's own gap between deals, not the industry's wait.

Baker's own account of what the first deal did is worth quoting, because it names three distinct motives rather than one. The securitization, he said, "increased our liquidity, leveled out our concentration of auto loans and provided transactional income, as well as providing a higher rate of servicing income throughout the life of the security." Liquidity is the cyclical reason. Concentration management and fee income are structural ones, and they do not go away when deposits return.

Nothing about that first deal was practically possible before 2017. The NCUA's securitization safe harbor, published in the Federal Register on June 30, 2017 and effective July 31, 2017, is what made it work: a rule at 12 CFR Part 709 defining how the NCUA Board, acting as liquidating agent or conservator, treats financial assets a credit union transfers in a securitization or participation. Without that clarity, capital markets buyers would not touch credit union paper, because they could not be certain they owned what they paid for. A separate 2017 NCUA legal opinion confirmed federal credit unions' authority to issue the securities at all, under Section 107(17) of the Federal Credit Union Act. The rule then sat unused for two and a half years. GTE used it first.

The shape of that timeline is itself an argument. One deal in November 2019, one more in March 2021, and then almost nothing until 2023, when seven priced at once and the pioneer finally came back. The rule landed in 2017 and sat unused for two and a half years. GTE proved it worked in 2019, and for three more years almost nobody followed. What changed was not the law or the technology. It was the liquidity, and the fit is close enough to test directly.

Loan-to-share stood at 84.1% in the fourth quarter of 2019, near a pre-pandemic high, when GTE went to market fully loaned up. Pandemic deposits then flooded in and the ratio collapsed to 75.6% by the third quarter of 2020 and to a record-low 68.8% by early 2021. Credit unions did not need funding, and 2020 produced no credit union securitization at all. As deposits drained back out and the ratio climbed above 81% by late 2022, seven deals priced in 2023 and the pioneer returned. Through 2023 the instrument behaved exactly as a liquidity valve should. Section IV is about what happened after that.

Read the table by its right-hand column and the pattern is hard to miss. First deal, a second issuer, the inflection year that also produced the first repeat issuances, the first cooperative structure, the first institution under $1 billion, the first collateral that was not a car loan, and the first stated commitment to keep going. Seven doors in under seven years, and the only year that produced nothing at all was 2020.

II · Why this instrument is different in kind

The trade press files securitization under loan sales, continued, as though it were a faster participation. The differences are the whole argument, and there are four of them.

The buyer is a different economy

A participation buyer is another credit union, funded by its own members' deposits. So the participation market's capacity is capped by the deposit health of the credit union industry itself. When deposits tighten system-wide, sellers multiply and buyers disappear in the same quarter, which is what happened in 2022 and 2023. A securitization buyer is an insurance company, an asset manager, a bond fund. Selling a participation redistributes paper within the industry's funding base. Issuing a bond brings new water into the pool.

The legal architecture is stronger, and the weak version is in court right now

A participation is a contract, and its central promise, that the buyer truly owns its share of the loans, has a known failure mode: recharacterization. If a court decides the sale was in substance a disguised loan, the buyer holds nothing but a claim against a bankrupt seller. That is a live dispute, not a law-school hypothetical. It sits at the center of the PrimaLend Chapter 11 covered in Issue 9, where participations sold to an affiliated entity are contested as true sales versus disguised financings.

The credit union industry has its own scar tissue on the same point. Taxi medallion participations spread the losses of a few New York originators across credit unions nationwide during the 2010s. Melrose Credit Union was placed in conservatorship on February 10, 2017 and liquidated on August 31, 2018, and the NCUA's Share Insurance Fund absorbed more than $750 million from medallion-related failures, a cost borne by credit unions that never originated or bought a medallion loan. The NCUA's own participation guidance is unusually blunt about the mechanism, warning that a seller "can create systemic underwriting and loan servicing risk to a large group of credit unions," and prescribing, in its words, caveat emptor and diversification. A securitization runs instead through a true sale into a bankruptcy-remote trust that the 2017 safe harbor addresses directly, with rated tranches, credit enhancement and a trustee. The structure is engineered against precisely the failure the participation market is litigating.

The disclosure regime is heavier, though still lighter than the public market's

Credit union ABS deals have come to market as Rule 144A private placements, so the loan-level Schedule AL disclosure that registered auto ABS files on Form ABS-EE does not apply. What does apply is rating-agency presale scrutiny and ongoing surveillance, investor reporting, and Rule 15Ga-2 findings filings on EDGAR. The Corporate One deal drew ratings from both S&P and KBRA. PenFed files ABS-15G through PenFed Auto Receivables Funding, LLC. That is far more third-party examination than any participation receives, where the buyer's entire visibility is the tape the seller hands over.

Baker also put a number on the thing that makes participations expensive in a way the dollar figures never show. Participations, he said, "take about as much time for each transaction regardless of size," because "it takes time to search for and connect with each participating financial institution." That is the operative constraint. A $1 million participation and a $23 million one cost roughly the same in effort, and GTE did both, so the average deal carried a fixed overhead the seller could not amortize away. A shelf inverts that: the setup cost is heavy once and near zero thereafter.

The machine runs again

A shelf, once built, is repeatable. PenFed has now used its four times and said on the record that it intends to keep using it. Corporate One closed its first multi-seller deal in January 2026 and has stated an ambition of two to four transactions a year. Nobody builds a machine to use it once.

III · What pushed them through the door

The trigger was cyclical and the record on it is clean.

Between early 2021 and late 2022, the system loan-to-share ratio moved from a record-low 68.8% to above 81%, as loan growth ran near 19% in 2022 while pandemic-era deposits drained away. Members moved cash to Treasuries and higher-yielding accounts, credit unions repriced certificates upward to slow the outflow, and cost of funds jumped. Underneath the funding squeeze sat the asset side of the trap: balance sheets full of 2021-vintage auto and mortgage paper written at the low rates of that year, performing perfectly and completely immobile. The loans were fine. They were also fuel that could not be burned twice. This brief does not attach a specific term structure to that vintage, because it has not sourced one.

The participation data from the peak shows both the surge and the strain. Credit unions sold $22.7 billion of non-real-estate loans in 2021, up 69% from $13.5 billion in 2020. But the top ten sellers accounted for $13.8 billion of that, and PenFed alone sold $6.4 billion, up nearly fourfold from $1.6 billion the year before. Oregon Community Credit Union, a $2.8 billion institution, sold $1.6 billion in 2021 against $143.3 million in 2020, an eleven-fold jump. Distribution was already concentrating in the hands of a small number of institutions, and several of them, PenFed and Oregon Community among them, went on to become securitizers. The capability was being built inside the old instrument before it moved to the new one.

Then there is the slower force underneath the cycle, and it is the one that does not reverse. The count of federally insured credit unions fell from 4,411 to 4,250 in the year to the first quarter of 2026, roughly 160 institutions in twelve months, with essentially nothing chartered to replace them. New charter formation collapsed to near zero across the 2000 to 2020 period while closures continued at roughly 100 to 200 a year, and the net count has been negative since the mid-1980s.

The institutions disappearing are the small ones. NCUA treats a credit union under $100 million in assets as small, and 56% of 2026 mergers to date involved institutions under $50 million. That is the profile of the traditional participation buyer: more deposits than local loan demand, and no capacity to originate at scale.

Two things cut against the tidy version of this and both belong on the record. First, merger approvals have slowed rather than accelerated, from a peak of 263 in 2014 to 157 in 2025, with 27 in the first quarter of 2026 against 35 in Q1 2025 and 26 in Q1 2024. Second, and more importantly, these are mostly not failures. In the first quarter of 2026 the NCUA approved 22 mergers for expanded services, three for inability to find officials and two for poor financial condition, and the expanded-services share has risen from 69% in 2025 to 82%. Healthy institutions are choosing to combine.

IV · The divergence that carries the argument

Here is the frame this brief exists to put on the record, and it is labeled as interpretation throughout.

If issuance were purely a liquidity valve, it should be closing. The pressure that opened it has eased. Loan-to-share fell to 81.5% in the first quarter of 2026 from 81.8% a year earlier. System net income ran 30.5% above the prior year at $20.4 billion annualized. Total assets reached $2.48 trillion. By any ordinary reading, a well-capitalized, profitable, re-liquefying system does not need to distribute.

Instead the valve widened. The first half of 2026 produced roughly $1.4 billion, against $2.1 billion for the whole of 2025 and a $2.6 billion record for 2024. Two thirds of a full year's volume in half a year, and it came with two categories that had never existed: a multi-seller deal carrying an institution under $1 billion in assets, and a securitization backed by something other than car loans. Continue that pace and 2026 clears the record. This brief does not annualize it, because the second half has not happened.

The 2026 bar is half a year and is drawn as such. What it establishes is that the valve stayed open, and widened, after the pressure dropped. That is what a ratchet looks like in its early years.

The pattern this cycle keeps producing

Subprime auto has been generating series that rise under stress and settle above their old floor rather than round-tripping. Extension usage is the cleanest example, and Issue 8 documented it: the tool spread under COVID, servicers built the capability, and usage never returned to its pre-pandemic level even after the emergency passed. America's Car-Mart ran a modification program across 28.9% of its receivables before disclosing it. In each case a behavior adopted under pressure became the baseline once the pressure passed, because the institutions had built the capability, normalized it internally, and had no incentive to unbuild it.

The scale objection answered itself

The multi-seller structure deserves its own paragraph, because it dissolves the objection that used to be the whole case against this thesis. In June 2014, then-NCUA Chairman Debbie Matz put the constraint plainly: "Most credit unions do not yet originate enough loans to sponsor securitizations, but for those that do, it is prudent to propose specific safety and soundness provisions." True then, and still true now, and now beside the point. The Alloya trust pooled $50 million each from three credit unions, none of which could have issued alone at scale. Six months later, Corporate One's $335 million transaction carried Day Air, a credit union under $1 billion in assets, into the ABS market alongside Wright-Patt and Everwise, with Stifel and Bank of America as joint leads and ratings from both S&P and KBRA. What was a structural barrier in 2014 became a pooling problem in 2025, and the corporate credit unions solved it the way aggregators always do.

The supervisor has noticed. The NCUA told attendees at its Capital Markets Symposium that securitization "is essential for larger credit unions to manage their balance sheets and tap into a broader investor base." An infrastructure layer has formed around the flow: corporate credit unions running the trusts, underwriters from Stifel to J.P. Morgan to Bank of America, and two law firms with assembly-line deal practices. Infrastructure is the most durable form of institutionalization there is. It does not dismantle itself when a ratio improves.

V · The counter-case, taken seriously

Four objections deserve a straight answer, because the honest version of this thesis is narrower than the trade press version.

The academic counterweight exists and it cuts cautionary. A 2026 study in Risks, using US credit union call report data from 1994 to 2024, finds that credit unions with heavier non-core lending exposure grow faster in loans and membership but carry weaker financial buffers, including lower net worth ratios, alongside higher delinquency. The sharpest finding in it is directly on point for this brief: of the non-core categories the authors test, loans held for sale show the strongest association with adverse buffer and asset-quality patterns, more so than purchased loans or lease receivables. Distribution is a capability, not a virtue. An originate-to-distribute credit union is a different risk animal from an originate-and-hold one, and the call report data already says so.
