The newly resurgent dollar pressured Asian currencies as markets revived bets that the U.S. Federal Reserve could possibly raise interest rates as soon as next month.
The advances in regional currencies were substantial. The dollar was fetching 102.03 yen at 9:51 a.m. HK/SIN, after flirting with levels around 100 yen just before the Fed's conclave in Jackson Hole, Wyoming.
The Australian dollar also felt the sting, fetching $0.7534 Monday morning, down from nearly $0.77 on Friday. The Singapore dollar was also lower, with the greenback fetching S$1.3614 Monday morning, up from as little as S$1.3469 on Friday.
The Malaysian ringgit also fell, with the dollar fetching 4.0425 ringgit on Monday morning, compared with as little as 4.0100 ringgit on Friday.
The dollar index, which measures the greenback's performance against a basket of currencies, jumped to 95.525 on Monday morning, from as low as 94.246 on Friday.
Analysts pointed to Fed Chair Janet Yellen's speech at the conclave on Friday as the reason for the newly resurgent dollar.
While markets still saw December as the most likely timing for a Fed rate hike, Yellen opened the door to a September hike when she said the case for a rate hike strengthened in recent months.
Fed Vice Chair Stanley Fischer further pushed the Fed's September meeting into play when he said in a CNBC interview that Yellen's comments were consistent with a Fed that could hike rates in September, as well as a second time this year.
