The US dollar was closely correlated with the 30-year Treasury bond (commonly called the "long bond") two weeks ago as the crisis in the credit marets neared its apex. When investors become spooked by risky market conditions, they tend to move their capital from stocks and other higher-risk investments to long-term US government bonds. While these offer very little return, they are considered nearly risk-free. The assumption is that such an investment can only go meaningfully awry if the government itself collapses. Indeed, EURUSD was as much as -84% inversely correlated with 30-year Treasuries.
Conditions have changed significantly since the G7 summit in Washington, DC produced coordinated intervention from global governments to reboot lending. LIBOR, the interest rate banks charge each other for overnight loans, has now fallen to the lowest level in over 4 years. The Ted spread*, a common measure of default risk, is down a whopping 35.69% since peaking just 10 days ago. * The price spread between 3-month US Treasuries and equivalent term USD-denominated overseas deposits.

Meanwhile, the EURUSD has become increasingly correlated with the MSCI Index of global stock performance. Amazingly, that correlation now stands at an impressive 85%.

The technical outlookt is supportive, with an index of the greenback's value against six major currencies positioned squarely at resistance below the upper boundary of channel established in mid-June.
