Prepayments (CK93)

Nykredit Realkredit published CK93 prepayment data for its Nykredit and Totalkredit mortgage bonds as of 18 September 2026. The notice contains no prepayment figures, change in outlook, or other material financial update; detailed data is available through Nasdaq Copenhagen and Nykredit's investor-relations website.

Analysis

This is a scheduled mortgage-market data release rather than a fundamental catalyst for NDAQ. The relevant information edge is confined to Danish callable mortgage-bond investors: realized prepayments can alter expected cash-flow duration, convexity hedging needs, and relative value across Nykredit/Totalkredit coupon stacks, but the release alone provides no directional signal without the underlying cohort-level prepayment speeds.

For the next several days, an upside surprise in prepayments would shorten effective duration in premium callable bonds and can create reinvestment pressure; a downside surprise extends duration and may require dealers and mortgage investors to add duration hedges. The broader transmission to Danish rates is likely modest unless speeds materially diverge from model assumptions while Danish yields are moving sharply, since hedging flows are most consequential near refinance windows and in high-convexity pools.

There is no credible read-through to Nasdaq Inc. earnings, exchange volumes, or valuation from this filing. The investable question is whether actual speeds differ enough from consensus to revise Nykredit mortgage-bond OAS and duration assumptions; absent that comparison, the correct stance is monitoring rather than deploying risk.

Key Decisions for Investors

• No directional position in NDAQ on this release; maintain exposures based on its U.S. market-data, index, and trading-volume catalysts rather than Danish mortgage prepayment disclosures.
• Request the attached CK93 file and compare realized speeds by ISIN, coupon, and loan vintage against dealer prepayment assumptions before trading Danish callable mortgages; flag a deviation greater than 10-15% versus expected CPR-equivalent speeds.
• If the data show broad-based slower-than-expected prepayments alongside rising Danish swap rates, evaluate a tactical duration-extension hedge in Danish swaps or Bund futures over a 1-4 week horizon; invalidate if rates retrace or subsequent refinancing data normalize.
• If speeds are materially faster than expected in premium cohorts, reduce exposure to premium callable Danish mortgage bonds and favor lower-premium/discount cohorts, subject to liquidity and OAS confirmation.
