<div>Oil prices hit the skids on 25 November after Iran and six world powers sealed a deal curbing its nuclear programme, a fillip for global economic growth that found expression in heartier share prices from Tokyo to Seoul.<br /><br />The agreement gives Iran some relief from crippling sanctions and is considered a big step toward a more lasting treaty. While Iran will not be allowed to increase its oil sales for six months, any easing of Middle East tensions tends to lead to lower crude prices.<br /><br />Brent crude oil shed $2.47 to $108.58 a barrel, its biggest daily drop in a month. US oil lost 88 cents to $93.96 a barrel.<br /><br />If sustained, the drop would be a net plus for spending power globally given high petrol prices essentially act like a tax on consumers.<br /><br />"Positive growth signals continue to trickle out across the global economy and there is growth convergence between developed and developing economies," said Peter Dragicevich, a strategist at CBA.<br /><br />"Our world GDP "nowcasting" estimate points to accelerating global economic growth in the final months of 2013. This is the general trend we expect to occur in early 2014."<br /><br />Attention in Asia was again on Japanese markets as a sliding yen promises to boost exports and profits. The Nikkei sped ahead by 1.3 per cent, having gained almost 11 per cent in little more than two weeks.<br /><br />On Wall Street, the Dow ended Friday with gains of 0.3 per cent, while the S&P 500 added 0.5 per cent for its first ever close above 1,800. Early Monday, S&P 500 futures had added another 0.3 per cent.<br /><br />But with money flooding into developed world assets, emerging markets are getting cold-shouldered. It was notable that MSCI's broadest index of Asia-Pacific shares outside Japan failed to make any headway at all last week, even as Wall Street made new peaks.<br /><br />So far on Monday, the index was up 0.4 per cent, as Seoul shares led the way with an increase of 0.7 percent.<br /><br /><strong>Yen Pain Is Euro's Gain</strong><br />In currency markets, the yen remained under pressure as investors use it for carry trades - borrowing the currency at super-low rates to invest in higher-yielding assets elsewhere.<br /><br />The dollar was up at 101.78 yen having cracked the old July top of 101.53. Much of the action was in the euro against the yen, which has had a barnstorming run to reach four-year highs above 137.80 yen.<br /><br />Euro-yen bulls now have their eyes set on a series of peaks from 2009 ranging from 137.43 all the way to 139.18, the top for that year. A break of the 139.18 level would take the euro to territory not visited since October 2008 -- very bullish from a technical point of view.<br /><br />Oddly, the gains have come even as the European Central Bank sounds ever-more dovish on policy.<br /><br />Earlier on Monday, ECB Executive Board member Benoit Coeure reiterated the central bank would take further action should inflation slow further. <br /><br />The single currency was been particularly strong against the Australian dollar, which has been undone by threats of intervention from the Reserve Bank of Australia.<br /><br />The euro leaped almost four full cents last week as the Australian currency crumpled to a three-month trough.<br /><br />Traders said the commodity currency could continue to struggle particularly if tensions between China and Japan grew.<br /><br />China at the weekend suddenly imposed new rules on airspace over islands at the heart of a territorial dispute with Tokyo, prompting Japan and ally the United States to warn of an escalation into the "unexpected".<br /><br />There is no major economic data due in Asia on Monday, while most of the U.S. economic releases will be front-loaded this week ahead of the Thanksgiving holiday on Thursday.<br /><br />The US diary includes figures on housing starts and prices, consumer confidence, durable goods orders and manufacturing in the Chicago area.<br /><br />(Reuters)<br /> </div>
