1. Investing in BTPs

BTPs are issued with maturities1from 18 months to 3, 5, 7, 10, 15, 20, 30 and 50 years. They are medium/long-term securities with fixed coupons that are particularly useful for those investors requiring constant payments2 every 6 months. The different maturities existing on the market allow investors to schedule regular cash flows during the whole year. Moreover, BTPs are particularly appreciated for their liquidity: before maturity, wholesale investors can buy or sell BTPs both on the regulated secondary markets (MTS) for trades of at least 2.5 million euros and on the over-the-counter market; while private citizens can perform these transactions on the regulated secondary market MOT (Government Bond and securities electronic market), where operations must be of at least 1,000 euros.
Among the dealers allowed to participate in the auctions, these securities are placed mainly with “Specialists in Italian Government Bonds” (that have a special section dedicated to them in the Public Debt website) who, on average, are awarded more than 90% of the total nominal amount issued at each auction


1To increase liquidity the Treasury issues 5½ year, 10½ year, 15½ year and 31 year BTPs, so that when the series of reopenings ends, residual maturity is near 5, 10, 15, 30 years.


2 To satisfy those investors who prefer securities offering a single payment at maturity (zero coupon bonds), in 1998 the Treasury initiated a program called Separated Trading of Registered Interest and Principal of Securities (STRIP), that allows them to split the capital and the coupons. The reconstitution of the “stripped” security by matching the coupons and the principal is possible at a later date. The Government Bonds that are subject to stripping are 10, 15 and 30 year BTPs.

3. Type of auction

BTPs are offered through a marginal auction with discretional determination of price and quantity issued. There is a mechanism of speculative bid exclusion which is described in detail in every issuance decree. The same decree sets supplementary placement terms, reserved to specialists in Government Bonds, technically treated as a subsequent tranche. The quota reserved to Specialist is equal to 30% of the amount allocated in the ordinary auction for the first tranche and 15% for further tranches. Only specialists who took part in the last auction, have access to this supplementary placement.
The amount of each of the five bids that every intermediary can place cannot be less than 500,000 euros.
Bidders can submit prices with a minimum tick of one euro cent or multiples thereof. For each security to be issued auction fees will be applied based on residual maturity, which will be set according to the number of days between the auction settlement date and the maturity date, according to the table below:


Residual maturity
