The rise in interest rates on the secondary markets represents a general trend and is linked to the forecast by the European Central Bank (ECB) of further rate hikes due to still too high inflation.
Higher long-term interest rates make borrowing more expensive, especially mortgages, and also represent bad news for state coffers if the government were to raise funds in financial markets.
At the beginning of December, the Belgian ten-year interest rate had fallen to 2.3%, the lowest point for months.
