A look back at the performance of the USDollar index over the past two days has exposed an interesting trend. The index has classically been known to fall with a rise in risk trends, because the US Dollar performs as a safe haven in most of its pairs. However, over the past two weeks, the USD/JPY pair’s positive correlation to risk trends has caused the greenback index to often rise on risk positive news.

The USDollar index is based evenly on the trading of the Dollar against the Yen, Pound, Euro, and Aussie. GBP/USD, AUD/USD, and EUR/USD will all usually rise on respective local positive economic releases or headlines, which will therefore often drive the USDollar index lower. This can be seen in the decline following today’s UK employment data during the European session, or during yesterday’s release of stronger Australian business confidence. The Pound and Aussie rose against USD after each respective release, sending the USDollar index lower.

However, the USDollar index has risen following stories that relate to the entire global economy and are not specific to one of the four economies in the USDollar index. President Obama’s announcement last night that the US will put military action against Syria on hold, as the world pursues diplomatic efforts, sent the US Dollar higher. A similar occurrence happened after a report of stronger Chinese industrial production.

The change in USDollar reaction to global risk trends is due to the Japanese Yen’s strengthening as a safe haven currency against the greenback. For the past two weeks, USD/JPY has surpassed AUD/USD in the level of sensitivity to global risk trends. The correlation between the USD/JPY pair and the S&P index rose from 0.27 for the past year to 0.76 for the past two weeks. While the correlation between AUD/USD and the S&P has only rise from 0.40 for the past year to 0.57 for the past two weeks.
