The U.S. dollar hit more than a one-month high on Tuesday as investors sought a safe haven due to concerns about China's economy, and traders braced for possible Japanese government intervention after the yen hit its lowest level since November.

The dollar index , which tracks the currency against its major peers, was up 0.301% at 103.170, hitting its highest level in more than a month.

Analysts said investors bought the dollar as shelter from concerns about the health of the global economy, particularly China.

Japan's yen was trading at its lowest level since November at 145.50 per dollar, with the dollar up 0.36% against the currency.

The Australian dollar slid to its lowest level since May and was last down 0.28% versus the U.S. dollar at $0.648. The currency is often seen as a proxy for investor sentiment on China.

Sterling was last down 0.16% to $1.2676, while the euro was 0.38% lower at $1.09045.
