Oil toiled at a more than one-year low after its worst month in a decade on Friday, while most major markets were keeping moves tight ahead of a weekend meeting between the U.S. and Chinese presidents Donald Trump and Xi Jinping.
Europe's main share indexes in London, Frankfurt and Paris all started their day lower after the latest batch of disappointing Chinese data had made for another twitchy Asian session overnight.
Frankfurt's export-heavy DAX and Britain's mainly domestic-focused FTSE 250 were both staring at their four consecutive months of falls. For the DAX it is its worst run since the back end of 2008.
The real humdingers though have been oil and Apple which have plunged 21 per cent and 18 per cent respectively, making it also their most wretched months since the financial crisis a decade ago.
"Expectations at the start of the fourth quarter were for a melt-up in risky assets, but two of the biggest trends have been a reversal of some of the few returns we have seen this year, which have been in oil and in tech," said head of macro strategy at State Street Global Markets' Michael Metcalfe.
"Also the market seems to be going into the G20 meeting with very low expectations of a ceasefire in the trade war. That may very well be correct but politics has proved very hard to predict this year."
Anticipation ahead of that meeting ensured cautious moves in the currency and bond markets.
The dollar index was a touch firmer at 96.86 .DXY -- having slipped this back this week after Federal Reserve chief Jerome Powell left investors wondering whether the U.S. central bank may be nearing the end of its current rate-hike cycle.
In early London trade, the euro fetched $1.13780, down 0.15 per cent. The dollar was flat at 113.45 yen while sterling held its ground at just under $1.28 having been lifted slightly this month by UK Prime Minister Theresa May securing a Brexit transition deal.
"We believe that Powell has not turned dovish but simply toning down his hawkish tilt," said Philip Wee, currency strategist at DBS in a note, forecasting another hike in December and as many as four next year.
U.S. money markets though, where the real money sits, are now pricing in only one rise next year.
Data on Friday added to the anticipation showing that growth in China's vast manufacturing sector had stalled this month for the first time in over two years.
"This is not a good year for multilateralism," a German government source told Reuters about the prospects for a G20 statement at the end of the meeting on Saturday. The negotiations are "very, very difficult."
MSCI's broadest index of Asia-Pacific shares outside Japan ended down 0.2 per cent with Korean shares one of the main drivers after the country's central bank lifted its interest rates in a widely expected decision.
In Japan, the Nikkei ended 0.4 per cent higher, while Chinese blue-chips, which have had a relatively steady month all considered, also advanced 1 per cent.
U.S. S&P E-mini futures ticked down 0.3 per cent, pointing to a weaker Wall Street session on Friday after a mixed overnight performance.
The Dow Jones Industrial Average fell 0.11 per cent, the S&P 500 lost 0.22 per cent, and the Nasdaq Composite dropped 0.25 per cent on Thursday.
Adding to apprehension ahead of the Trump-Xi meeting, a U.S. official said White House trade adviser Peter Navarro, who has advocated a tougher trade stance with China, would attend.
Trump himself had sent mixed signals saying "I think we're very close to doing something with China but I don't know that I want to do it," as the money coming in from his tariffs was so lucrative.
Back in the oil markets, crude was starting to slip again having tried to steady on news that Russia is increasingly convinced it needs to reduce oil output along with the Organization of the Petroleum Exporting Countries (OPEC).
OPEC and its allies are meeting in Vienna on Dec. 6-7. Brent and U.S. WTI crude were both down around 0.6 per cent at $59.51 per barrel and $51.38 a barrel. Spot gold barely budged at $1,223 per ounce.
