LONDON, Nov 2 (Reuters) - World shares rallied on Friday on hopes that the United States and China were starting to repair their badly damaged trade relations, while bumper U.S. wage data helped the dollar regain some strength.
The signals on trade triggered a global surge in risk appetite that lifted metals and swathes of trade-sensitive currencies and bond markets, but it was equities that saw the strongest reaction.
A buoyant Asian session, where most of the major markets gained by 2.5 to 4 percent, put emerging market stocks up 3 percent and on course for their best day and week since early 2016.
"When Trump wants to bump the market ahead of the mid-terms, the market likes it," said Saxo Bank's head of FX strategy, John Hardy, referring to next week's mid-term U.S. elections.
In Europe, Germany's export-heavy DAX jumped 1.5 percent in its best session since July. Traders, though, did trim back Wall Street futures gains after a strong monthly U.S. non-farm payrolls report spurred rate rise expectations.
U.S. job growth rebounded sharply last month and wages recorded their largest annual gain in 9-1/2 years, the data showed, pointing to further labour market tightening that could encourage the Federal Reserve to raise interest rates again in December.
Those numbers contrasted with data this week showing slowing factory growth around the world, but for the day at least those worries were soothed by the brighter U.S.-China mood.
The focus now is on whether the strong jobs report, particularly the wages data, will help push 10- and 30-year U.S. bond yields up towards 3.5 percent.
The signs are that it could. European bond yields were already up before the data and the 10-year Treasury yield looked to be creeping higher again too.
The figures also helped the dollar claw off a week-low , and make some ground against the safe-haven yen at 113.00 yen.
China's yuan had earlier strengthened to a high of 6.9092 per dollar in onshore markets and also gained in offshore trade, pulling away from the sensitive 7 to the dollar level.
The euro edged up 0.15 percent to $1.1426 and the Australian dollar gained 0.5 percent to $0.7240.
Hopes Britain is closing in on a transitional deal for when it leaves the EU next year pushed sterling higher to $1.30, after enjoying its best day of the year on Thursday.
If the pound doesn't skid later it will be its second-best week of the year so far.
"Were it not for Brexit uncertainty, the Bank of England would probably have laid the groundwork (at its meeting on Thursday) for its next rate hike," BNP Paribas analysts said in a note.
The expected rise on Wall Street is likely to be tempered by Apple shares, which tumbled 5.6 percent in premarket trading after the company warned on Thursday about its upcoming holiday season sales.
In an interview with Reuters, Apple CEO Tim Cook said some of the forecast disappointment was explained by releasing its top-end iPhone models, the XS and XS Max, in the fiscal fourth quarter.
Cook also said foreign exchange rates would have a $2 billion negative impact on Apple's sales forecast. Cook added the firm was also "seeing some macroeconomic weakness in some of the emerging markets," although he didn't specify which ones.
The tech sector has taken a beating on Wall Street over the last month and Apple's weak forecast fed into the same investor fears that have caused shares of Facebook, Amazon and Google to tumble.
In commodity markets, industrial metals led the charge on the hopes a Trump-Xi trade deal would prevent China's resource-hungry economy faltering.
Three-month copper on the London Metal Exchange climbed as much as 2.8 percent to $6,264 a tonne, its highest in a week.
Other base metals were up across the board too, with zinc rising 2.5 percent, nickel climbing 2.9 percent, lead up 3.1 percent and aluminium gaining 1.9 percent.
Oil prices were less energetic but managed to reverse early Asian losses, with U.S. crude last at $63.51 a barrel and Brent crude a touch higher at $72.99.
They were restrained by a report that the U.S. government has agreed to let eight countries, including close allies South Korea and Japan, as well as India, keep buying Iranian oil after Washington re-imposes sanctions.
"Oil prices look to remain under pressure, as fears of global oversupply have returned with a vengeance," said Ashley Kelty, oil and gas research analyst at Cantor Fitzgerald Europe.
