Post updated Feb, 2011.
The UK has had a persistent current account deficit for the past couple of decades. The deficit has never gained much concern from politicians or economists. However, with the recent increase in the size and significance of the deficit there are an increasing number of Economists warning that a current account deficit can pose a threat to long term growth
The data shows a sharp deterioration in the third quarter of 2003. This quarterly deficit is equivalent to 5.1% of GDP.
