The fall comes as no surprise and is part of a downward trend that started almost a year ago. Record low levels of interest have been set over the past few months.
A year ago, just before the new Federal Government took office, the rate of interest Belgium had to pay on long term loans had topped 6%. Since then the rate has consistently fallen and has been below 6% since the beginning of June.
Low interest rates are good news for the treasury as it means that the state can lend money more cheaply.
