The euro zone's current account surplus dropped to €4.6 billion in April from €10.3 billion the previous month, European Central Bank data showed.

The current account on the balance of payments, which includes imports and exports in goods and services plus all other current transfers, is a closely tracked indicator of the ability of an area to pay its way in the world.

It is crucial for the long-term confidence of investors and trading partners.

Over the 12 months to April, the current account showed a surplus of €18.8 billion, compared with a deficit of €18.6 billion the same time a year earlier, the data showed.
