What are BTPs and how do they work

When you buy a 10-year BTP, you're lending €1,000 to the state. The state pays you a coupon every year (say 3%) and returns the initial €1,000 at maturity. The coupons are the return you earn while you wait.

The actual yield depends on the price you pay for the bond. If you buy the BTP at €950, the yield will be higher than the nominal 3% because you still get €1,000 back at the end. If you buy it at €1,050, it will be lower.

A BTP's price moves in the opposite direction to interest rates. If rates rise, existing BTPs with low coupons become less attractive and their price falls. If rates fall, BTPs with higher coupons become more appealing and the price rises.

Confidence in Italy matters too: if investors fear the state might struggle to repay, they demand higher yields to buy BTPs and prices tend to fall. This is also reflected in the BTP-Bund spread.

BTPs suit those looking for stability and a predictable return over time. They don't offer big gains like stocks, but they tend to lose less during crises. They're often used to diversify a portfolio or for those with a long investment horizon.

One caveat: if you sell before maturity, the market price could differ from what you paid. So the longer you hold the BTP, the closer the actual return gets to what was promised at the start.
