Americans must prepare themselves for a massive collapse in the dollar as investors around the world dump their US assets, a former Bank of England policymaker has warned.
The long-held assumption that US assets - particularly government bonds - are a safe haven will soon be overturned as investors lose their patience with the world's biggest economy, according to Willem Buiter.
Professor Buiter, a former Monetary Policy Committee member who is now at the London School of Economics, said this increasing disenchantment would result in an exodus of foreign cash from the US.
The warning comes despite the dollar having strengthened significantly against other major currencies, including sterling and the euro, after hitting historic lows last year. It will reignite fears about the currency's prospects, as well as sparking fears about the sustainability of President-Elect Barack Obama's mooted plans for a Keynesian-style increase in public spending to pull the US out of recession.
