UPDATE 1-European bond yields slip before central bank meetings, trade deadline

European government bond yields edged lower on Wednesday before a deadline for new U.S. tariffs on Chinese goods this Sunday, while central bank meetings from the U.S. Federal Reserve and the European Central Bank kept investors sidelined. Benchmark 10-year bond yields in Germany fell two basis points to -0.3150%, moving further away from a three-week high of -0.26% reached last week. Comparable yields in France and Belgium were down a similar amount.

"It is basically the Fed, ECB and the tariffs that are keeping everybody on edge with all these headlines on the trade front not removing the broader confusion," said Benjamin Schroder, a rates strategist at ING Bank in London. Another round of U.S. tariffs on Chinese goods is due to take effect on Dec. 15, and Britain holds an election on Thursday. Both supported demand for fixed-income assets after some mixed economic data from Germany in recent days.

The Fed concludes a two-day meeting on Wednesday, with last Friday's U.S. jobs report expected to give the U.S. central bank all the reason it needs not to cut interest rates further. Strategists at Mizuho expect Fed Chairman Jerome Powell to imply two-way risks to the Fed's outlook. Money markets expect no change at the ECB meeting. Signs that the worst may be over for the euro zone economy buy the ECB's Christine Lagarde some time, analysts say.

An economic surprise data index for Europe published by Citibank is at its highest level in nearly two years. With currency market volatility near record lows, demand for peripheral European debt remained supported, with yields in 10-year Italian bonds holding near a two-week low of 1.345%.
