Please see a brief summary below of the major global currencies.
AUD: The weak US payrolls number hit every commodity-related currency hard because, as legend has it, if America sneezes the global economy catches a cold. That has not prevented the Aussie from hitting a record high against the pound and coming close to its all-time high against the dollar but it might be a sign that an end to the one-way street is in sight.
USD: If President Obama and the house of representatives cannot reach agreement on the budget and the debt ceiling the United states government will run out of money on 2 August. Few believe it will come to that but the possibility makes investors nervous about the dollar. Last week's horrendously soft payrolls number is another reason for their dislike.
NZD: New Zealand's products are mainly meat and dairy, exports which unlikely to be compromised in any major way by the possible fall in demand for minerals and metals. In the last week the Kiwi has scored record highs against the US dollar, the euro and the pound. It might have further to go.
CAD: Canada's economy is closely aligned to that of the United States and to global demand for oil, of which it is a major exporter. With the US economy stuttering and the risk of a financial crisis in Europe dampening global risk-appetite the Loonie is fighting on two fronts.
ZAR: While the rand is vulnerable to any reduction in demand for commodities, one of its products - gold - is as popular today as it ever has been. On top of that South Africa's 5.5% benchmark interest rate comfortably outweighs its 4.6% inflation rate, a situation that no European or North American currency can match.
EUR: The failure of EU ministers to come up with a comprehensive and permanent solution to the Greek debt crisis is turning into a disaster for the euro. The longer they fail to sort it out, the worse investors fear the problem will become. Italy has now joined Greece, Ireland, Portugal and Spain on the list of government bonds that investors least like to own. As a result the euro has lost ground and is likely to lose more.
GBP: A week ago it seemed that the notion of the pound as a safe-haven currency was a busted flush. After topping the league table in the last seven days the idea seems less crazy. With nothing in the economic data to drive it forward (higher unemployment, flat retail sales), no other argument springs to mind. A safe-haven pound still sounds like a crew-member for the ship of fools but it might just float, given the shortcomings of the opposition.
