ICE Municipal AAA Yield Curve

A transparent municipal benchmark with the proof to match.

The ICE Municipal AAA Yield Curve is a transparent, transaction-driven curve, supported by our evaluators and backed by 15+ years of history. Yields update continuously throughout the trading day in response to real trades, so issuers, investors and advisors can see the curve move and understand why it did. The result is a transparent, rules-based curve that brings institutional rigor to municipal benchmarking.

Key benefits

Rules-based and fully transparent

The curve uses observed trades that meet certain criteria to produce a rules-based transaction-driven curve supported by ICE’s evaluators. It is administered under evaluator oversight, with a dedicated evaluator monitoring and maintaining it throughout each trading day as their primary responsibility.

Continuous intraday updates

Updated continuously throughout the trading day, ICE’s curve offers deeper insight into a fragmented market that traditionally relies on an end-of-day approach. The curve applies intraday and EOD market moves across most of the investment-grade muni universe.

~850,000 bonds priced with precision

Approximately 850,000 tax-exempt bonds are attached to the curve, pricing off it either directly or indirectly. When the attached universe moves, the curve moves with it.

15+ years of history

The curve has been calculated off real transactions for more than 15 years and has been in production for seven years, providing the back-testing history needed for issuers, investors, advisors and more to benchmark with confidence.
