SINGAPORE, July 19 (Reuters) -Asian shares are set to end the week on a sour note, as uncertainty across major economies added to headwinds for investors even as the global rate easing cycle gets under way.

It has been a turbulent week in markets, with a tech sell-off sparked by deepening Sino-U.S. trade tensions, uncertainty over U.S. President Joe Biden's fate in the presidential race, disappointing Chinese economic data and a lacklustre third plenum outcome casting a shadow over the global mood.

In the foreign exchange market, Tokyo's recent bouts of intervention also kept traders on edge.

"We could just be getting a taste of things to come. And that is more turbulence," said Matt Simpson, senior market analyst at City Index.

MSCI's broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS slid 1.56% and was headed for its worst week in three months with a nearly 3% loss.

Japan's Nikkei .N225 fell to a more than two-week low and was last down 0.09%, extending its sharp 2.4% fall from the previous session.

The Nikkei was on track to lose 2.7% for the week, also its steepest weekly decline in three months.

European shares looked set for a mixed start, with EUROSTOXX 50 futures STXEc1 up 0.08%, while FTSE futures FFIc1 fell 0.4%.

S&P 500 futures ESc1 tacked on 0.16%, while Nasdaq futures NQc1 gained 0.3%.

Technology stocks continued to struggle, with South Korea's tech-heavy KOSPI index .KS11 and Taiwan stocks .TWII both falling 1.5% and 2%, respectively.

South Korean chipmaker SK Hynix 000660.KS slid more than 1%, though Japan's Tokyo Electron 8035.T, a chipmaking equipment manufacturer, rebounded some 2.5%, after an 8.75% tumble on Thursday.

Shares of Taiwan's TSMC 2330.TW, the world's largest contract chipmaker, fell 2.7%, even after the company posted better-than-expected earnings on Thursday and raised its full-year revenue forecast.

In China, investors were left disappointed over the lack of details provided on the implementation steps for achieving economic policy goals at the conclusion of its closely watched plenum on Thursday.

Chinese officials on Friday acknowledged that the sweeping list of economic goals contained "many complex contradictions", pointing to a bumpy road ahead for policy implementation.

Chinese blue-chips .CSI300 were last a touch higher, though the CSI300 Real Estate index .CSI000952 slid more than 2%, as an anaemic property sector continued to weigh on China's growth outlook.

The Shanghai Composite Index .SSEC edged 0.08% lower, while Hong Kong's Hang Seng index .HSI fell 2.1%.

"Apart from very broad-brush platitudes devoid of stimulus, economic policy references of quality over quantity may also imply willingness to stomach slower overall growth," said Vishnu Varathan, chief economist for Asia ex-Japan at Mizuho Bank.

The onshore yuan CNY=CFXS was weaker on the day at 7.2666 per dollar.

RATES VIEW

The euro EUR=EBS was last 0.08% lower at $1.0887, having fallen 0.4% in the previous session after the European Central Bank (ECB) kept rates on hold as expected but left the door open to a September cut as it downgraded its view of the euro zone's economic prospects.

"The policy statement gives little away, offering no meaningful changes from June - continuing to stress a data-dependent approach to policy setting," said Nick Rees, FX market analyst at MonFX.

"We still think that a September cut remains the base case."

The dollar was meanwhile on the front foot, distancing itself from a four-month low hit earlier in the week against a basket of currencies =USD.

Sterling dipped 0.05% to $1.2939, while the Australian dollar AUD=D3 fell 0.12% to $0.6698.

The dollar was partially underpinned by strong U.S. manufacturing data and jobless figures that did little to suggest a significant slowing in the labour market, though traders are still pricing in a September rate cut from the Federal Reserve. FEDWATCH

The yen JPY=EBS fell 0.1% to 157.55 per dollar, though was headed for a slight weekly gain, helped by suspected bouts of intervention from Japanese authorities to prop up the currency and as an acceleration in the core inflation last month kept alive expectations that the Bank of Japan could soon raise interest rates.

In commodities, oil prices fell. Brent crude futures LCOc1 eased 0.46% to $84.72 a barrel, while U.S. crude futures CLc1 slid 0.59% to $82.33 per barrel. O/R

Gold XAU= fell 0.8% to $2,424.93 an ounce, retreating from a record high hit earlier this week on the prospect of lower global interest rates. GOL/
