In most countries, the price quotation method is usually used to quote the national debt futures, with the net price of national debt with face value of 100 yuan (excluding the holding period interest) as the benchmark, and decimal system is adopted after the decimal point. CICC treasury bond futures are quoted in this way. For example, the quotation "97.250" means that the future price of government bonds with a face value of 100 yuan is 97.250 yuan, which is the transaction price excluding the interest of the holding period.
