(Sept 5): Malaysia’s ringgit headed for its biggest weekly decline in more than a month on speculation a strengthening U.S. economy will prompt the Federal Reserve to bring forward its timetable for raising borrowing costs.

Growth in U.S. manufacturing and services industries topped economists’ estimates in August, data showed this week before today’s jobs figures. Malaysia may report its trade surplus narrowed to 3.3 billion ringgit ($1 billion) in July from a year earlier, the smallest gap in 12 months, according to a Bloomberg survey. The numbers are due at 12:01 p.m. local time.

“The strengthening U.S. economy is creating expectations that U.S. rates will rise sooner rather than later,” said Jonathan Cavenagh, a Singapore-based currency strategist at Westpac Banking Corp. “Malaysian trade data are due but are unlikely to move market sentiment.”

The ringgit fell 0.2 percent today and 1.1 percent for the week to 3.1860 per dollar as of 10:17 a.m. in Kuala Lumpur, according to data compiled by Bloomberg. One-month implied volatility, a measure of expected moves in the exchange rate used to price options, rose 63 basis points from Aug. 29 and 15 basis points today to 6.24 percent.

The Bloomberg Dollar Spot Index climbed to a 13-month high after the European Central Bank unexpectedly cut its benchmark interest rates yesterday. The ringgit weakened as the stimulus measures boosted sentiment in the greenback, Cavenagh said.

Fed Chair Janet Yellen told central bankers in Jackson Hole, Wyoming, last month that U.S. policy makers may raise interest rates sooner than investors anticipate amid labor- market gains.

U.S. employers probably created 230,000 new jobs last month after taking on 209,000 workers in July, according to a Bloomberg survey.

Malaysian government bonds fell this week, with the yield on the 3.654 percent sovereign notes due October 2019 climbing four basis points, or 0.04 percentage point, to 3.73 percent, data compiled by Bloomberg show. The yield advanced one basis point today.
