LONDON, April 23 (Reuters) - World stocks slipped on Monday as investors braced for a blizzard of earnings from the world's largest firms, while keeping a wary eye on U.S. bond yields as they approach peaks that have triggered market spasms in the past.
The yield on 10-year U.S. Treasuries US10YT=RR hit its highest level since January 2014 at 2.9790 percent in early European trade, as the spread over the German equivalent DE10YT=RR briefly touched its widest level in 29 years. were also getting a global round of economic surveys that should show if economic softness in the first quarter was just a passing phase linked to wintery weather and the Lunar New Year holidays. from Japan, France and Germany were all relatively reassuring.

Of particular concern for U..S. analysts will be executives' views about their exposure to China, the world's No. 2 economy and an important market for many U.S. companies amid the recent worries about a trade war.
U.S. Treasury Secretary Steven Mnuchin said on Saturday he may travel to China, a move that could ease tensions between the two supersized economies.

The discussions were really more around the governor's actions at the PBOC (People's Bank of China) and certain actions they've announced in terms of opening some of their markets, which we very much encourage and appreciate."
Back in commodity markets, the spike in oil has driven up both market expectations of future inflation USIL5YF5Y=R and long-term bond yields.
Yields on 10-year Treasuries US10YT=RR are at the highest now since early 2014 at 2.977 percent and again threatening the hugely important 3 percent bulwark.
The last time yields neared this number in 2013 it rocked risk appetite and sent stocks sliding. It also came shortly before oil prices went on a mighty 75 percent tumble.
"Another $5/barrel increase in oil will be enough for U.S. 10-year yields to threaten 3 percent. Oil is now at the cusp of levels where higher prices will spark greater FX and broader asset market volatility," said Deutsche Bank's macro strategist, Alan Ruskin.
Traditionally the dollar had a slight negative correlation with oil, mostly because the dominant causation goes from dollar weakness to rising oil prices, he added.
"If oil helps push the 10-year yield into new terrain for this cycle, this will play at least mildly USD positive in a change of correlation."
Indeed, dealers cited widening yield differentials for the dollar's broad rally on Friday.
The currency was last at 107.89 yen JPY= and testing major resistance in the 107.90/108.00 zone which has held solid since mid-February.
The dollar index edged up to 90.528 DXY , and further away from last week's low at 89.229.
The euro was easier at $1.2251 EUR= , having repeatedly failed to break above $1.2400 in the last couple of weeks.
Investors are awaiting the European Central Bank's policy meeting on Thursday amid talk policymakers feel it is still too early to announce a timetable for winding down its bond buying.
