What is US 10-Year Breakeven Inflation Rate (US_BREAKEVEN_10Y)?

US 10-Year Breakeven Inflation Rate is a reference rate — a standardized benchmark published by an official body, used as the basis for pricing financial contracts, loans, and derivatives. Reference rates provide a transparent, manipulation-resistant alternative to panel-based rates.

Reference rates are embedded in loan agreements, bond indentures, and derivatives as the floating-rate component. Regulators and central banks have actively promoted official reference rates as replacements for rates that were subject to manipulation, improving the integrity of financial benchmarks globally.
