                                 By Alex Richardson	
                                 SINGAPORE, Nov 23 (Reuters) - The dollar and U.S. 
Treasuries rose and U.S. stock futures fell on Tuesday after a 
major exchange of artillery fire on the Korean peninsula.	
                                 The euro, stocks and commodities also fell as a bailout 
for Ireland failed to allay fears of a wider crisis.	
                                 North Korean artillery fired dozens of shells onto a South 
Korean island near their disputed sea border, wounding several 
people, setting fire to buildings and prompting a return of 
fire by the South, Seoul's military and media reported. 
 [] 
                                 Seoul's financial markets had already closed but 
international markets reacted, with the dollar up 0.4 percent 
on the day against a basket of currency. The dollar index 
 rose from 78.77 before the reports to a 
session high of 79.07.	
                                 U.S. 10-year Treasury futures, a traditional safe haven, 
were up 0.4 percent <TYc1> on the day and U.S. S&P 
500 stock index futures were down 0.9 percent 
 <SPc1> . The won tumbled in offshore markets 
 and the yen eased.	
                                 European markets were seen opening mixed, with the Korean 
drama adding to concerns about the euro zone.	
                                 
 
    As Beijing tightens monetary policy to rein in 
inflation, worries of faltering Chinese demand for raw 
materials -- in the short term at least -- knocked metals 
prices and were another factor hammering shares, particular in 
resource-focused Australia.	
                                 "Investors seem unable to move beyond European debt 
contagion fears and concerns of further China policy 
tightening," said IG Markets strategist Ben Potter.	
                                 The euro had initially spiked on Monday on news of a 
European Union and International Monetary Fund bailout for 
Ireland, where a property bust has pushed the nation's banks 
to the brink of collapse and blown a hole in the public 
finances.	
                                 But it swiftly reversed course as the coalition government 
in Dublin, deeply unpopular after presiding over the implosion 
of an economy dubbed the "Celtic Tiger" for its double-digit 
growth in the late 1990s, looked to be facing a struggle to 
pass an austerity budget that is a condition of the aid. 
 [] 
                                  The single currency was driven back below $1.36 on 
Tuesday as the Irish turmoil stoked fears that a crisis that 
has already engulfed Greece will spread to other indebted euro 
zone nations, with Portugal and Spain in nervous bond 
investors' sights.	
                                 "They've addressed the Greek problem, they're addressing 
the Irish problem, people are now questioning where is the 
next one ... the political turmoil in Ireland also doesn't 
help," said Grant Turley, strategist at ANZ in Sydney.	
                                 Asian stock markets fell, following declines on Wall 
Street the previous day, with MSCI's index of Asia Pacific 
shares outside Japan shedding 1.9 
percent. Tokyo markets were closed for a holiday.	
                                 Australian shares lost 1.2 percent to 
hit a seven-week low. Banks and miners led the retreat, with 
National Australia Bank down 1.8 percent 
and BHP Billiton off 1.7 percent.	
                                 The biggest stock market falls were in Hong Kong 
 and Shanghai , down 2.4 
percent and 1.9 percent respectively, where investors dumped 
mining and metals stocks.	
                                  Moves by the authorities to cool the property market 
continued to weigh in Hong Kong, where the property sub-index 
 fell 3 percent.  
                                 On Monday U.S. financial stocks had slid on fears of 
exposure to Europe's debt woes and concerns about a broad 
insider trading probe. The KBW bank index 
fell 1.5 percent and JPMorgan Chase & Co 
 fell 2.3 percent. 
                                 	
                                 DOWNSIDE RISK 
                                 The euro traded around $1.3555, below 
Monday's session trough of $1.3574. The single currency had 
risen as high as $1.3786 on Monday. 
                                 "The fact that sentiment turned so quickly, that the Irish 
government is heading towards an election and that Moody's 
talked about downgrading Ireland are all not helping," said 
Greg Gibbs, strategist at RBS.	
                                 "It reveals a lack of underlying demand for European 
sovereign and financial assets and point to the downside risk 
for the euro."	
                                 Against the yen, the euro slipped to around 113.40 
 from two-week highs near 115.0 yen.	
                                 A stronger dollar often weighs on commodity markets, 
making assets priced in the U.S. currency more expensive for 
holders of other currencies.	
                                 U.S. crude oil futures lost 50 cents, or around 0.6 
percent, to trade at $81.24 a barrel, gold 
 fell around 0.5 percent and copper and zinc were also 
weaker.
