TOKYO, Dec 6 (Reuters) - Asian stocks slipped across the board on Wednesday as various factors including weaker metals prices and monetary policy concerns in China soured investor risk sentiment.
Spreadbetters saw bearish equity sentiment extending into Europe, predicting Britain's FTSE would open 0.5 percent lower, seeing Germany's DAX start down 0.6 percent and France's CAC opening 0.5 percent lower.
MSCI's broadest index of Asia-Pacific shares outside Japan dropped to a two-month low and was last down 1.5 percent.
The index took early cues from overnight losses on Wall Street, where the stuttering technology sector had taken a further toll.
The fall in the index deepened as Asia's equity markets suffered losses, with Shanghai stocks falling to three-month lows and Hong Kong's Hang Seng dropping to a one-month trough amid fears over central banks tightening liquidity.
Japan's Nikkei was last down 2 percent with non-ferrous metals producers suffering large losses after copper's slide overnight to a two-month low.
Perceived geopolitical risks also dented confidence with U.S. President Donald Trump due to recognise Jerusalem as the capital of Israel later on Wednesday.
In the debt markets, the two-year Treasury yield hovered near a nine-year high, elevated by the Fed's tighter policy path and on expectations the U.S. Congress will pass tax reform legislation that gives the economy a fiscal boost.
But the 10-year Treasury yield declined, flattening the yield curve further. The curve has flattened as investors see limited room for long-term U.S. inflation.
The dollar fell, weighed by lower long-term U.S. yields as broader investor risk appetite recedes. The dollar index against six major currencies slipped 0.2 percent to 93.213.
The greenback lost 0.4 percent to 112.110 yen and the euro rose 0.15 percent to $1.1842 after shedding 0.35 percent the previous day.
The pound stood at $1.3426 for a loss of 0.1 percent, having taken a small knock after Sky News reported of a foiled plot to assassinate British Prime Minister Theresa May.
Sterling had fallen to as low as $1.3370 on Tuesday on disappointment after May failed to clinch a deal to open talks on post-Brexit free trade with the European Union.
Bitcoin continued its relentless advance, climbing to a fresh record high of $12,205.46 on the BitStamp exchange . Its latest rise took bitcoin's gains so far in 2017 above 1,100 percent.
