SYDNEY – Asian shares were mixed and the dollar stood tall on Friday ahead of a key US jobs report as investors braced for more aggressive rate hikes from the Federal Reserve.

MSCI's broadest index of Asia-Pacific shares outside Japan remained largely unchanged in early Asia trade, but was headed for its worst weekly performance in seven with a drop of 3 percent, as rising expectations of hawkish global rate hikes hit risky assets.

Japan's Nikkei was mostly unchanged, South Korea gained 0.5 percent.

All eyes are now on US August nonfarm payroll data due on Friday.

Analysts expect 285,000 jobs were added last month, while unemployment hovered at 3.5 percent. Investors may not like a strong number if it supports a continuation of aggressive rate hikes from the Fed, which could further boost the US dollar and spur a sell-off in bonds.

Futures markets have priced in as much as a 75 percent chance the Fed will hike by 75 basis points at its September policy meeting, compared with a 69 percent probability a day earlier.

The dollar index, which measures the greenback against a basket of six major currencies, stood near its 20-year high at 109.55 on Friday. It eased slightly against the Japanese yen after notching a 24-year peak against the rate-sensitive currency in the previous session. The dollar was up 0.7 percent for the week.

"Markets broadly continue to absorb that central banks’ 'whatever it takes' to lower inflation message means much slower global economic growth." said Tobin Gorey, agriculture strategy director at the Commonwealth Bank in a note. 

Oil prices tumbled 3 percent overnight before recovering some ground on Friday but were on track to post their worst weekly drop in four on fears weak global growth will hit demand.

Brent crude futures rose 1.3 percent to US$93.56 a barrel on Friday while US West Texas Intermediate crude futures were up by a similar margin.

Overnight, the US S&P 500 index climbed 0.3 percent, while the Nasdaq Composite finished down 0.3 percent.

In Europe, fears of a recession are on the rise, with a survey showing on Thursday that manufacturing activity across the euro zone declined again last month as consumers feeling the pinch from a deepening cost of living crisis cut spending. 

Treasury yields eased slightly ahead of potentially strong payrolls data.

The yield on benchmark two-year notes hovered at 3.5117 percent, a touch lower than its 15-year high of 3.5510 percent, while the yield on 10-year bonds stood at 3.2609 percent, compared with its previous close of 3.2650 percent.

Gold was slightly higher. Spot gold was traded at US$1697.59 per ounce.
