GDANSK/TOKYO, Feb 28 (Reuters) - World stocks fell to

their lowest levels in almost four weeks on Friday, while the

dollar hovered near multi-week highs, as the prospect of higher

U.S. tariffs sent jitters through markets and revived concerns

about an escalating global trade war.

Technology shares took an additional hit following a sharp

sell-off in AI darling Nvidia ( NVDA ) and other so-called

"Magnificent Seven" Wall Street mega-cap stocks, as investors

judged the chipmaker's earnings report harshly a day after its

release.

U.S. President Donald Trump said on Thursday that 25% duties

on imports from Canada and Mexico will come into effect on March

4 - not April 2 as he had suggested a day earlier - and said

goods from China will be subject to an additional 10% duty. This

week he also floated 25% tariffs on shipments from the European

Union.

"A market that had reduced its sensitivity to recent tariff

headlines has had to reconsider that reaction function," said

Chris Weston, head of research at Pepperstone.

"The skew for risk in the near term suggests the downside

has further to go here."

Tariff fears sent risk-sensitive currencies such as the

Australian dollar sliding, while the U.S. dollar was set for its

best week since late January.

Bitcoin dipped below $80,000 for the first time in more than

three months, following a towering rally late last year

on optimism that the Trump administration would boost the asset

class.

Europe's STOXX 600 was down 0.6%, after the index

fell about 0.5% on Thursday. The sub-index of technology stocks

slid 1.4%.

The pan-European index was roughly flat on the week,

after rising for nine consecutive weeks.

World stocks were on track for their worst

week since mid-December, slumping more than 2%. On Friday, the

index fell to its lowest in almost a month.

U.S. stock futures, however, were broadly higher

, suggesting Wall Street shares should recover some ground

after a selloff the previous day.

A broadly firmer dollar weighed on commodities including

gold.

EYES ON PCE

While the threat of escalating tariffs has spurred dollar

strength, it has also stoked worries about its impact on the

U.S. economy.

Recent U.S. data has been soft, and traders have reacted by

pricing in at least two quarter-point Federal Reserve interest

rate cuts this year, with the first as early as July.

Investors will keep a close watch on the Fed's preferred

inflation gauge - the PCE price index - set for release later in

the day. Monthly non-farm payrolls figures are due a week from

now.

In Asia, Japan's Nikkei tumbled 2.8%, buckling under

the weight of a stronger safe-haven yen.

Hong Kong's Hang Seng slid 3.3%, and mainland blue

chips declined by 1.9%.

Many analysts project that Trump's trade policies raise the

odds of additional stimulus from next week's meeting of China's

National People's Congress.

The dollar index - which gauges the greenback against

six major peers including the euro, yen and franc - touched

107.45 for the first time since February 13.

The euro languished around its lowest since

February 13, after the single currency fell 0.8% on Thursday. It

was last trading at around $1.03.

In the euro zone, preliminary data on Friday showed that

French inflation dropped below 1% for the first time in four

years in February. German and Italian data are released later.

"With the European Central Bank meeting coming next week,

it's interesting to see the inflation numbers," said Jan von

Gerich, chief analyst at Nordea.

"The market usually moves more to these numbers from the big

countries than the final euro area number that we get next

week."

Bitcoin last changed hands 6.3% weaker at $78,984,

hovering around its lowest since November 10.

Gold sagged 0.6% to $2,856 per ounce, the lowest

since February 10.
