A euro challenge?
For the euro to begin to challenge the reserve role of the US dollar, a virtual revolution in policy would have to take place in Euroland. First the European Central Bank (ECB), the institutionalized, undemocratic institution created by the Maastricht Treaty to maintain the power of creditor banks in collecting their debts, would have to surrender power to elected legislators. It would then have to turn on the printing presses and print euros like there was no tomorrow. That is because the size of the publicly traded Euroland government-bond market is still tiny in comparison with the huge US Treasury market.
