The Credibility of a Promise

Inflation-protected bonds provide protection against inflation; the government will be able to partly fight inflation by issuing these types of bonds. 
This was stated by Mehdi Nosrati, an economic analyst, in a write-up for the Persian daily Donya-e-Eqtesad. A translation of the text follows:
“Next Iranian year [2022-23] will see a much lower inflation rate,” Minister of Economic Affairs and Finance Ehsan Khandouzi made this old, undelivered promise last week.
