Switzerland has a very stable economy due to its strong ties to neighboring European countries through foreign trade and exports. Over 50% of Switzerland's exports are purchased by countries in the Eurozone, mainly Germany. While agriculture and small manufacturing make small contributions to GDP, the dominant industries are banking, insurance, and tourism, which employ a large portion of the workforce and contribute significantly to economic growth. However, the removal of currency controls linking the Swiss franc to the euro in 2015 hurt export-reliant industries like manufacturing and tourism by strengthening the franc, though it avoided an economic recession.
