Four business days after the July 4, 2026 begin-construction deadline, the specific market signal to watch has moved. The tax-credit insurance market has widened again, taking the total post-deadline widening on late-week cost-incurred EPAs to 65 to 110 basis points versus the early-June paid-at-execution cohort. The transferability primary desk started quoting a two-tier price on Tuesday afternoon, splitting between physical-work and cost-incurred paper for the first time in the post-deadline cycle. Tax-equity primary is still holding a single-price convention through Wednesday morning. The intra-pathway gradient the July 7 note flagged as absent from the primary market is starting to leak in from the transferability side rather than from tax-equity directly.
Where the insurance market is now
Monday afternoon quoted the first specialty-carrier move: two carriers priced late-week EPAs 45 to 70 basis points wider than the pathway average, with explicit carve-outs on related-party restructurings executed after June 20. Through Tuesday and into Wednesday morning, the widening extended to a third specialty carrier and the pricing window opened another 20 to 40 basis points on the same cohort.
The specific carrier movement matters because it is the first market that quotes cohort-level, not pathway-level, risk. A cost-incurred EPA signed on June 12 with a paid-at-execution deposit and an arms-length counterparty prices materially inside a cost-incurred EPA signed on July 2 with a 3.5-month payment deferral and a post-vacatur related-party restructuring. The tax-equity primary market has been treating both as cost-incurred paper. The tax-credit insurance market is now writing a distinction into premium.
Three carve-outs are recurring in the Tuesday and Wednesday quote sheets. First, related-party EPAs executed after June 20 are being priced with a specific pricing-standard rider that requires third-party fair-market-value support at closing. Second, 3.5-month payment-deferred deposit structures are being priced with a supplier-continuity representation that requires the developer to maintain an alternate-supplier standby for the deposit obligation. Third, EPAs where the deposit ratio sits within 5 to 20 basis points of the 5-percent floor are being priced with a facility-cost audit rider that opens the denominator for post-closing adjustment.
The three riders together move the insurance product from a pathway-neutral wrapper to a cohort-conditional wrapper. Two of the three riders open contract terms the developer had already treated as closed at execution. That is the specific reason the specialty carriers can widen 65 to 110 basis points on late-week paper while the tax-equity primary market is holding pathway pricing flat. The insurance carriers are quoting different risk. The tax-equity primary desk is quoting one risk.
The transferability desk started splitting on Tuesday afternoon
The transferability primary market has been holding a single-price convention on cost-incurred paper since the June 6 vacatur of Notice 2025-42. That convention broke on Tuesday afternoon at two of the three most active desks. The Tuesday afternoon quote sheets from those desks introduced a physical-work versus cost-incurred split at 25 to 35 basis points, applied to new-issue transferability paper covering post-July-4 solar credits.
The break matters more than the size. Twenty-five to 35 basis points is inside the range the insurance market has been quoting for two sessions. What is new is that the transferability desk started conceding a distinction it had been resisting since the vacatur. The desk-side rationale is straightforward on the two data points available: the specialty insurance quotes are now consistent enough across three carriers that the transferability desk can no longer place late-week paper without factoring in the insurance rate. The insurance rate is now inside the credit price rather than layered on top of it.
The third transferability desk is still quoting a single-price convention as of Wednesday morning. The pricing gap between the single-price and two-tier desks is roughly 25 basis points on late-week EPAs, which is exactly the size of the two-tier split. That is a clean arbitrage window for placement, and the buy side is already routing late-week paper to the two-tier desks and physical-work paper to the single-price desk.
Tax-equity primary is still holding a single price
The tax-equity primary market is materially slower to reprice than transferability. The Q3 2026 origination cycle on new-issue tax-equity paper is only just opening, and the first Q3 syndications will not price until the second half of July at the earliest. The single-price convention is holding through Wednesday because there is no new paper being placed to break it.
The lookback question on already-syndicated paper is different. Deals that priced in Q2 2026 on a single-price convention now sit in a market where the transferability desk is quoting a 25 to 35 basis point gradient and the insurance market is quoting a 65 to 110 basis point gradient. Secondary trading on already-syndicated tax-equity paper is thin enough that the mark-to-market question is a policy-choice question at the fund level, not a market-observable question. Two funds have marked their Q2 2026 syndicated cost-incurred paper down 15 to 25 basis points through Tuesday close. The rest of the syndicated book is still at par.
The specific number to watch is the first Q3 2026 tax-equity primary syndication that lands after mid-July. The pricing on that syndication will resolve whether the intra-cohort gradient prices in on the primary side or whether the tax-equity market continues to hold a pathway-neutral convention. If the first syndication prices on a two-tier convention consistent with the transferability desk, the gradient closes in one to two additional syndications and the market settles into the new pricing regime by August. If the first syndication prices on a single-price convention, the transferability-versus-tax-equity spread opens further and the Q3 origination cycle spends the quarter arbitraging between the two.
The dated Q3 watchpoints
Three specific dates now sit on the Q3 2026 calendar as pricing checkpoints.
The first is the earliest expected date of the first post-deadline Q3 tax-equity primary syndication, currently tracking to the third or fourth week of July. That syndication will resolve the pathway pricing question described above.
The second is the September Treasury guidance window on the post-vacatur cost-incurred pathway. Treasury has indicated informally through professional-services channels that it is targeting September for the next round of guidance on related-party pricing standards under the Notice 2018-59 framework, and on the 3.5-month payment mechanics for the specific case of deposit obligations executed under a post-vacatur EPA. Guidance in September compresses the interpretive-risk floor on the 73 GWdc cost-incurred pool by the end of Q3. Guidance slipping to Q4 widens the floor through year-end.
The third is the first supplier-side or developer-side stress event inside the 285-day payment-deferred window. That window opened July 5. Q3 will run 82 days of it. Any specific event in Q3, a module supplier bankruptcy filing, a tracker supplier receivership, a developer refinancing failure on a portfolio holding late-week EPAs, would put a specific cohort of 4 to 7 GWdc under simultaneous specific-performance review before the September Treasury window closes.
The transmission question the insurance market is answering
The reason the insurance carriers can widen 65 to 110 basis points on late-week paper without waiting for tax-equity is that the insurance carriers are pricing a different underwriting question. Tax-equity is pricing cash-flow risk on a project that will produce electricity for 20 to 30 years. Insurance is pricing audit-defensibility on a documentation stack that will sit under the 2029 to 2032 IRS examination cycle. The two questions have different time horizons, different failure modes, and different remedies. Audit-defensibility is what the July 3 note called out as the interpretive-risk layer sitting on top of the cost-incurred pool. That layer is now being priced by the insurance carriers and, as of Tuesday afternoon, by two of three transferability desks.
Whether tax-equity primary joins them on the first Q3 syndication is the specific empirical question the Q3 2026 origination cycle now has to answer. The insurance market has moved. The transferability desk has partially moved. The primary tax-equity desk is next.
