Belgian business investment took a hit during the economic crisis, but it wasn't as bad as it could have been considering the overall drop in GDP. The investment in Belgium follows the ups and downs of the economy, but it didn't decrease as much as in neighboring countries. Factors like low demand, reduced profits for companies, higher borrowing costs, and tighter credit conditions contributed to the decline. Despite these challenges, Belgian firms stayed relatively strong compared to others. However, there are still risks that could slow down the recovery of investment and economic growth in the future.
