Index spread is live (FRED · ICE BofA US HY OAS). Cohort-level spread and issuer counts have no wired source and are withheld rather than estimated. Window is a declared analysis parameter, not a measurement.

CohortIssuersLendersSpreadState
Cohort A · maturity inside 18 monthsIssuers share a refinancing window but not a sector or rating, making time the common pressure.———Structural
Cohort B · single-lender dependenceEach facility depends on one lending relationship whose withdrawal can force a private repricing.———Watch
Cohort C · covenant reset pendingTerms must be renegotiated before maturity, so lender consent matters before cash is due.———Monitored
Rest of indexMaturities and lenders are more dispersed, leaving no shared refinancing date visible in the average.———Unchanged
Why the index hides it
An index average blends issuers by weight, sector and rating, but it does not show who must refinance at the same time or who relies on the same lender. A small cohort can therefore carry a shared maturity and funding problem while the broader index remains calm.
What would falsify it
The structural reading would fail if the affected issuers refinanced on ordinary terms, added lenders without difficulty and showed no common maturity or covenant pressure. If the same instruments moved together without those constraints, sentiment would explain the move better than the cohort's financing arrangement.

The cohort's facilities sit toward the concentrated end of the lenders-per-facility distribution. A broad book can absorb one lender's refusal; a narrow book turns that refusal into the central financing event.

IssuerMaturityLendersSpreadStructural note
Issuer A———Refinancing depends on the lender that arranged the existing bilateral facility.
Issuer B———Its maturity falls inside the shared window without a demonstrated syndication route.
Issuer C———A covenant reset gives the incumbent lender influence before refinancing begins.
Issuer D———The facility has several participants, but decision-making remains concentrated.
Issuer E———Its lender base is less concentrated, making it the cohort's cleaner comparison.
Issuer F———The lender relationship and refinancing date overlap, leaving little room for delay.
The last comparable windowWhat happened the previous time a cohort defined this way reached its date
T−6 months
The affected facilities began to trade or quote wider while the index and ratings remained broadly steady.
T−2 months
Issuers sought extensions, added security or opened talks with new lenders before a full refinancing was available.
T
The narrowest lender relationships set terms privately, and the public market offered little evidence of the final clearing level.
T+6 months (outcome)
The cohort refinanced unevenly: issuers with broader lender access reset terms, while dependent issuers carried forward the original concentration.
The precedent shows how a shared maturity can expose lender concentration; it does not establish that every issuer will need an extension or that the same terms will recur.
