- Eurogroup approves Greek bailout.- Euro strengthens after announcement.- Footsie slips early on with oil stocks weighing on index.Despite Eurozone finance ministers doing what many had expected by approving the next tranche of aid for Greece, the Footsie opened moderately lower on Tuesday morning, as investors shifted their attention to the challenges that lay ahead in getting both the Greek and the wider Eurozone economy back on track.EUROGROUP SIGNS OFF ON €130BN GREEK BAILOUTIn a statement issued this morning, the Eurogroup announced that they have reached a deal with Greece on the €130bn bailout package. "We reiterate our commitment to provide adequate support to Greece during the life of the programme and beyond until it has regained market access, provided that Greece fully complies with the requirements and objectives of the adjustment programme," the statement said.As part of the package, the country's debt-to-gross domestic product ratio is expected to fall from around 160% to 120.5% by 2020. Private sector bond-holders are to take a 53.5% hair-cut on Greek debt. Other elements include a lower margin charged by the official sector on loans to Greece, to 150 basis points from 200 basis points previously.The announcement sparked a rise in the euro against the dollar, which has since come back down. The euro rose to $1.3292, compared with the previous close of $1.3242. After the open in London, the single currency was trading at the $1.3261 level.Some analysts seem to be attaching particular importance now to whether or not the country's debt swap will be successful and if credit default swaps on Greek debt will be triggered. Furthermore, some observers are now asking the difficult question of whether enough has been done or not. Having said that, there seems to be a rather broad consensus that a "disorderly default" has been avoided. OIL STOCKS PROVIDE A DRAGFinancials were on the rise in early morning trade with Admiral, Barclays, Schroders, Lloyds and Ashmore all performing well. However, oil stocks were leading the downside as oil prices retreated after a strong rise yesterday which saw the price of Brent crude reach the $120-a-barrel level. The spike in oil prices was triggered after oil rich Iran threatened to stop oil exports to more European countries after Tehran reduced sales to French and UK companies the previous session. Iran said the threat was in retaliation to EU countries if they continued to carry out what it called "hostile acts".Tullow Oil was the heaviest faller early on despite saying that one of its exploration wells (Jupiter-1) offshore Sierra Leone has successfully encountered hydrocarbons.
