US deficit data fuel anxieties on dollar

The US current account deficit suffered its fastest quarterly deterioration in the final months of last year, ballooning to a record 7 per cent of national income.

The worse-than-expected deficit rekindled fears among economists that global imbalances would undermine the dollar.

The deficit hit $225bn (€187bn, £129bn) in the fourth quarter, up from $185.4bn in the third, which was 5.9 per cent of gross domestic product. For 2005 the deficit was $805bn, 6.4 per cent of national income.

“The bottom line is that a current account deficit of this unparalleled magnitude is unsustainable and there is no hope of it being painlessly resolved through higher exports alone,” said Paul Ashworth, an analyst at Capital Economics.

Total US exports are just 10.5 per cent of GDP. In order to eliminate the deficit, exports would need to increase by 70 per cent. “This is clearly not going to happen,” said Mr Ashworth. “Instead it will require a big dollar depreciation alongside much weaker domestic demand for imports.”

The US current account position has long benefited from a positive income balance, with US investors receiving more from overseas assets than the country paid to foreign investors. In 2005, however, this started to turn round. In the fourth quarter the income balance was $2.4bn in deficit. Economists believe that this deficit will become ever larger as the impact of years of net selling US assets is felt.

So far the US has had little trouble funding the current account deficit, with overseas investors willing to buy ever greater quantities of US assets and Asian central banks buying US bonds to prevent their currencies from rising.

Since the start of 2006, the dollar has appreciated by about 3.5 per cent in trade-weighted terms.

Economists suspect that support for the dollar may start to ebb in 2006. Funding the deficit in 2005 was helped by the American Job Creation Act, which included a provision temporarily allowing US multinational companies to repatriate foreign profits at a lower tax rate.

The US also benefited from a rising interest rate gap against the eurozone and Japan. Neither of these boosts are likely to be present in 2005.

Economists are also concerned that money borrowed from overseas is being used for current spending by consumers rather than being funnelled into corporate investment, which might enhance the ability of the US to pay back overseas money. US companies have become net savers while US consumers and the government are both borrowing heavily.

Aside from a fall in the dollar, the deficit could be narrowed if US consumers cut back over coming years.
