Why choose an 18-month term?

An 18-month term is a useful middle ground when you believe rates are near their peak and want to lock them in for longer than a year without committing to a full 2-year term.

Rates at 18 months are sometimes higher than 12-month terms, particularly when banks are competing for longer-term deposits. Worth comparing directly before choosing.
