Generally speaking, a term investment or savings certificate earns a higher rate of interest than a conventional savings account. Unlike with a savings account, however, your funds cannot be accessed right away. You can only access them once the set term of the instrument comes to an end.
A term investment or savings certificate is also relatively safe, since the capital is paid back on the specific date on which the instrument matures (unless the bank where the account is managed goes bankrupt). For a number of term investments, capital of up to 100 000 euros (per person and per bank) that you have invested is also protected by the deposit guarantee scheme, subject to certain conditions.
