The euro zone's current account surplus grew to €21.5 billion in April, European Central Bank data showed today. 

The monthly figure is higher than a surplus of €19.6 billion in March, according to revised data. 

The current account on the balance of payments includes payments for imports and exports in both goods and services plus all other current transfers.

It is a closely tracked indicator of the ability of a country or area to pay its way. 

It is also crucial for the long-term confidence of investors and trading partners, and an important factor in the value of a currency, in this case the euro, on the foreign exchange market. 

Over the 12 months to April, the current account showed a surplus of €248.7 billion, compared to €177.7 billion a year earlier, the data showed.
