One by one, the eurozone, the Swedes, the Swiss and now even the Japanese, are turning off the tap of ultra-cheap credit that has flushed the global system for the past year, keeping the ageing asset boom alive.
The "carry trade" - as it is known - is a near limitless cash machine for banks and hedge funds. They can borrow at near zero interest rates in Japan, or 1pc in Switzerland, to re-lend anywhere in the world that offers higher yields, whether Argentine notes or US mortgage securities.
The Bank of International Settlements last year estimated the turnover in exchange and interest rates derivatives markets at $2,400bn a day. "The carry trade has pervaded every single instrument imaginable, credit spreads, bond spreads: everything is poisoned," said David Bloom, currency analyst at HSBC. http://tinyurl.com/zondz
This week's turmoil involving the Icelandic krona was just a brief squall preceding the storm to come. I do not think there is any way all these financial positions can be unwound without a major crash in asset values. There is a cerain irony that the Bank of Japan governor who is likely to be our nemesis goes under the name of Mr Fukui. http://tinyurl.com/ff5k9
