- StanChart tumbles on Iran dealings- IHG jumps after half-yearly report- Optimism increases in the EurozoneThe Footsie edged higher on Tuesday morning after having closed at a three-month high the day before but Standard Chartered grabbed the headlines early on, taking a tumble in the opening hour on the back of allegations of hiding dealings with Iran.The FTSE 100 hasn't closed above 5,800 since it finished at 5,812 on May 1st. Stocks raced ahead yesterday after Germany backed the European Central Bank's (ECB's) plan to buy Spanish and Italian bonds. Analyst Craig Erlam from Alpari said this morning that risk appetite is expected to remain high: "This is likely to continue to be the trend over the coming weeks until we see some concrete steps taken by the central banks. It is rare that comments made in the Eurozone keep sentiment high for sustained periods of time. However, there is something different about this one."Meanwhile, Spain's Prime Minister Mariano Rajoy hinted over the weekend that the country may need to ask for aid. "Signs that the Spanish government will accept a bailout, along with European and Asia's being able to respond to the solid US jobs report from Friday caused markets to trade higher yesterday," said trader Simon Furlong from Spreadex."UK and European manufacturing data this morning will help keep market momentum if we see some encouraging numbers," he said.FTSE 100: StanChart drops 19% early onEmerging markets-focused banking titan Standard Chartered fell after the US banking regulator accused it of collusion with the government of Iran to hide transactions from authorities. Nomura, Oriel Securities and Bank of America all downgraded their ratings on the stock this morning.According to the notice served on Standard Chartered Bank (SCB), a wholly owned subsidiary of Standard Chartered: "For almost ten years, SCB schemed with the government of Iran and hid from regulators roughly 60,000 secret transactions, involving at least $250bn, and reaping SCB hundreds of millions of dollars in fees. SCB's actions left the US financial system vulnerable to terrorists, weapons dealers, drug kingpins and corrupt regimes, and deprived law enforcement investigators of crucial information used to track all manner of criminal activity." Nomura has cut its recommendation on shares of StanChart to neutral from buy. On fundamentals alone it is their preferred stock in the sub-sector, but they now see material headline risk. More specifically, they note that the amounts in question are large (250bn dollars), the hard language used by the regulator and allegations that these operations were led by its most senior management.
