World stocks waver as investors catch central bank jitters

World stocks stumbled and bond yields edged lower on Tuesday as hotter than anticipated European inflation numbers jangled investor nerves ahead of a slew of earnings reports, central bank meetings, and key U.S. economic data.

Meanwhile, more than 100 S&P 500 companies, including Apple AAPL, AMZN and Google parent Alphabet GOOG, are expected to report results this week, which also includes the release of closely watched U.S. employment numbers.

Tuesday sees the release of fourth-quarter labour costs, while Friday brings the all-important January non-farm payrolls report.

"Reality is setting in," said Bruno Schneller, a managing director at INVICO Asset Management in Zurich.

Equity markets may have factored in the end of central bank rate hikes, but they do not yet reflect the potential hit to earnings from a slowing economy, Schneller said.

"Recent corporate results, especially 2023 guidance, indicate a negative outlook leading us to maintain a reduced position in equities," he said.

"In the shorter term, there doesn't appear to be an obvious safe haven for investors," said Schneller.

European shares dropped on Tuesday, dented by healthcare stocks, with the Euro Stoxx index SSXXP down 0.8%, Germany's AX DAX falling 0.7% and the FTSE UK100 0.8% lower. U.S. stock futures, the S&P 500 e-minis ES1!, were down 0.4%.

"This whole week is about rate hikes but from a credit markets point of view, credit spreads have traded back to the pre-Ukraine invasion levels," said Azhar Hussain, head of global credit at Royal London Asset Management.

Credit spreads, the difference between the yields of two different debt instruments with the same maturity, are often taken by traders to indicate market stability and company financial health.

"Over the last 12-months, yields have traded much higher than predicted a year ago. Compare that to valuations and the two are out of sync," said Hussain.

"Where investors should feel more nervous is with company valuations," he said.

U.S. stock futures (.ESc1), (.NQc1) fell, pointing to a lower open for the benchmark indexes following Monday's losses.

At the end of the Fed's two-day policy meeting on Wednesday, investors will be glued to Chair Jerome Powell's news conference for clues on whether the rate-hiking cycle may be coming to a close, and for signs of how long rates could stay elevated.

U.S. Treasury yields edged lower ahead of the central bank meetings and economic data, with the benchmark 10-year note down 3 bps at 3.522% US10Y.

The two-year yield (US2YT=RR), which rises with traders' expectations of higher Fed fund rates, fell 3 bps on the day to 4.226%.

In currencies, the U.S. dollar index, which was poised for its fourth month of declines, was up 0.2% at 102.44 against a basket of other major currencies. DXY

The euro EURUSD fell 0.1% to $1.0835, but was still heading for a gain of 1% this month.

In the energy market, oil prices fell ahead of the expected hikes by central banks and on the back of data that showed Russian exports are rising, despite international sanctions. Brent crude BRN1! fell 1% to $84.08 per barrel. Spot gold GOLD also dropped 1% to $1,902.68 per ounce, driven lower by a stronger dollar.
