The seasonally adjusted trade deficit widened to €8.92 billion in September, from a revised €8.33 billion in August (originally reported at €8.09 billion).

Imports declined by 1.4 percent to €58.05 billion, consistent with slowing domestic demand. But that was more than offset by a 2.8 percent drop in outward shipments to €49.13 billion. Both sides of the trade equation hit their lowest level in over a year. The annual export decline now stands at 2.3 percent, while the fall in imports has slumped by 13.1 percent.

The merchandise trade balance measures the difference between imports and exports of goods. The level of the international trade balance, as well as changes in exports and imports, indicate trends in foreign trade and can offer a guide to an economy's competitiveness.

Changes in the level of imports and exports, along with the difference between the two (the trade balance) are a valuable gauge of economic trends here and abroad. While these trade figures can directly impact all financial markets, they primarily affect currency values in foreign exchange markets. Given the size of the French economy, the euro can be sensitive to changes in the trade balance. The bond market is also sensitive to the risk of importing inflation. This report gives a breakdown of trade with major countries as well, so it can be instructive for investors who are interested in diversifying globally. For example, a trend of accelerating exports to a particular country might signal economic strength and investment opportunities in that country.
