The dollar eased against the safe-haven yen and the low-yielding euro on Monday as investors around the world knocked down equities and trimmed bets against currencies popularly used to fund risky carry trades. Under carry trades, investors sell a low-yielding currency to buy riskier, higher-yielding ones for better returns. When volatility rises in global financial markets and stocks fall, they tend to take these positions off the table.
Most emerging Asian currencies slid on Monday and were set to post steep monthly losses as top U.S. Federal Reserve officials left the door open for an interest rate hike in September and Chinese stocks tumbled again.
Oil futures soared on Monday for a third consecutive day, rising more than 8 percent, as a downward revision of U.S. crude production data and OPEC's readiness to talk with other producers helped extend the biggest three-day price surge in 25 years. U.S. crude oil prices have skyrocketed more than $10 a barrel in three days, erasing the month's declines as a series of relatively small-scale supply disruptions and output risks prompted bearish traders to take profits on short positions, which had been near a record a week ago. On Monday, prices fell initially but reversed course mid-morning. The three-day gains were more than the 20 percent mark that often signals a bull market. Even so, few were prepared to call a definitive end to the slump.
