SYDNEY, July 24 (Reuters) - Shanghai shares led Asia higher on Tuesday as China touted fiscal action to support the world's second largest economy, while stellar results from internet giant Alphabet underpinned the tech sector generally.
Global bonds remained under pressure on speculation the Bank of Japan may soon trim its massive stimulus. In China, government bond yields jumped and the offshore yuan hit a one-year low after China's cabinet said it would pursue a more vigorous fiscal policy and as traders bet on further easing in monetary conditions. blue chips .CSI300 rose 1.5 percent to a one-month high, while MSCI's broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS added 0.6 percent.
The better mood helped Japan's Nikkei .N225 edge up 0.5 percent, even as a disappointing reading on factory activity suggested the threat of a trade war was starting to bite. futures for the S&P 500 .SPX firmed 0.2 percent, and European bourses looked set to start higher
Tech stocks got a boost from the parent of Google GOOGL.O which jumped 3.6 percent after hours to hit a record high, valuing the group at a cool $870 billion. made up for an otherwise dull Monday on Wall Street where the Dow .DJI ended down 0.06 percent, while the S&P 500 .SPX gained 0.18 percent and the Nasdaq .IXIC 0.28 percent.
WHO WILL BUY THESE BONDS?
Bond bulls were still smarting from speculation that the Bank of Japan is close to announcing measures to scale back its massive monetary stimulus, a risk that lifted long-term borrowing costs globally. were worried that Japanese investors would have less incentive to hunt offshore for yield, said ANZ economist Felicity Emmett.
"The 10 basis-point steepening in the Japanese yield curve is massive in the context of a market that rarely moves more than 1 basis point," she added.
"It reflects a broader fear that central banks are reducing their purchases while U.S. bond supply is set to rise significantly."
As a result, 10-year U.S. Treasury yields hit their highest in five weeks around 2.96 percent US10YT=RR and were again nearing the psychological 3 percent bulwark.
GDP GUESSING GAMES
Part of the shift in yields was because of chatter that data on second-quarter U.S. economic growth (GDP) due on Friday would easily top current forecasts of 4.1 percent.
Dealers noted some media reports President Donald Trump himself was predicting an outcome of 4.8 percent. That would not be out of bounds given the much-watched Atlanta Fed GDP tracker puts growth at an annualised 4.5 percent.
Such a strong outcome would only add to the risk of faster rate hikes from the Federal Reserve and underpin the dollar.
