LONDON (MarketWatch) -- European stock markets dropped on Monday, tracking losses seen overnight in Asia and last week in the U.S., where worries over rising Treasury yields and jitters over monetary policy spooked investors.

The Stoxx Europe 600 index gave up 0.4% to 305.17, erasing a 0.3% gain from Friday.

Banks posted some of the biggest losses in the pan-European index, with UniCredit SpA off 1.5%, Deutsche Bank AG (DB) down 1% and Banco Santander SA (SAN) 0.9% lower.

Shares of Glencore Xstrata PLC erased 1.7% after reports said the resource giant is expected to write down the value of assets from recently acquired Xstrata. A representative from the firm declined to comment. Glencore Xstrata reports first-half earnings on Tuesday.

On a more upbeat note, shares of Atlas Copco AB climbed 2.1% on news the Swedish engineering group will buy Edwards Group Ltd. (EVAC) for $10.50 a share in cash, valuing the transaction at around $1.6 billion, including debt.

More broadly, investors were cautious of placing any big positions amid uncertainty over the U.S.'s monetary-easing program. Federal Reserve Chairman Ben Bernanke has said any tapering of the bank's $85-billion-a-month asset purchases will only happen if data improve, and recent jobless claims and an improvement in core retail sales have added to speculation it could happen as soon as September.

The concerns pushed the yield on the 10-year U.S. Treasury to hit the highest level in two years on Friday. In return, the Dow Jones Industrial Average (DJI) suffered its biggest weekly percentage drop and point loss of 2013.

The negative mood also spilled over into the new trading week in Asia, where most markets closed lower.

On Wednesday, minutes from the Fed's latest policy-setting meeting will be released, which could provide more information about the central bankers' view on the tapering process.

Among country-specific indexes in Europe, the U.K.'s FTSE 100 index dropped 0.3% to 6,481.84, while France's CAC 40 index lost 0.7% to 4,093.81. Germany's DAX 30 index shaved off 0.7% to 8,331.95.
