The U.S. Investment-Grade Universe Beyond Ten Years

Every USD-denominated investment-grade note with ten or more years to maturity (2036 and beyond), reconstructed at the individual-bond level from published fund constituent data and segmented by sector. Real issuers, coupons, maturities, and CUSIPs, not index summaries.

Fund-level yield and duration are the published VCLT figures; the note count, issuer count, and sector split are derived directly from the 2,838 corporate holdings maturing in 2036 or later (weighted-average coupon 4.82%, weighted-average 22.4 years to maturity, cross-checked against Vanguard’s stated 22.3-year average effective maturity).

Bid / Offer and Last Price

Two venues, side by side

A two-sided dealer market at the New York 5pm close is licensed data (Bloomberg, Tradeweb, MarketAxess) and is not public. So this shows the two public angles side by side for a sector-diverse set of the most liquid names. Left: real closing bid, ask, and spread from Börse Frankfurt, a regulated exchange, at its 17:30 CEST close, which is 11:30 in New York. Right: the US TRACE tape (via Moment) last traded price and yield through the US session, the closest public read on the New York close, though it is a last print, not a two-sided quote.

A separate, conservatively filtered set: 161 USD sovereign notes from 15 countries that carry firmly investment-grade ratings. Sub-investment-grade and split-rated issuers present in the parent fund (Turkey, Nigeria, Egypt, Colombia, Bahrain, Oman, South Africa, Argentina) were deliberately excluded so nothing in this list is mislabeled on credit quality.

Rating bands show Moody’s / S&P / Fitch broad buckets as of mid-2026. Ratings move; confirm live per issuer before use. Parent fund VWOB carries a 6.7-year duration across all maturities; this sleeve is filtered to the 2036-and-beyond long end only.

How this was built, and what it is not

  • Source. Full daily constituent files published by the fund issuer (Vanguard), pulled at the bond level: issuer, coupon, maturity, face, market value, CUSIP, ISIN, portfolio weight. 2,849 corporate lines and 921 sovereign lines as of 30 June 2026.
  • Filter. Corporates restricted to maturities in 2036 or later (2,838 notes), giving every line ten or more years to run. Effective portfolio duration is 12.1 years.
  • Sectors. Assigned by a transparent, rule-based classifier on issuer identity; 97.0% of weight is classified, the residual 2.97% sits in “Other / Diversified” (all sub-0.1% individual positions). The long universe carries a segment the short one does not: taxable university and nonprofit debt (MIT, Stanford, USC and peers), broken out as its own sector.
  • EM sleeve. Whitelisted to established investment-grade sovereigns only; junk and split-rated names removed.
  • What this is not. Not non-public data, no such data is legally obtainable by scraping, and not investment advice. Per-bond live yield and price are available on request via FINRA TRACE by CUSIP; the coupons shown are contractual, not current market yields.
Method: individual-bond reconstruction from public constituent files via Firecrawl / direct retrieval, classified and filtered programmatically. The value is the assembly, an issue-level, sector-tagged, quality-screened universe compiled in one place, not any secret source.
