Google’s surprise $12.5 billion bid for Motorola Mobility this morning is a bold attempt to move the needle for Google on several fronts. Google is going all in, dipping into its $39 billion of cash to make its biggest acquisition ever. The deal signals that mobile will be one of Google’s main growth drivers and that growth will come from entering new markets, specifically mobile hardware. With the acquisition, Google gains a portfolio of 17,000 patents and another 7,000 patents pending globally, an area where it is a currently a laggard. But more than anything, it signals how crucial it is for Google to control the Android experience from soup to nuts. There may now be 150 million Android phones and phones running the Android operating system command the largestmarket share smartphone , but Android the most popular single smartphone by far is still the iPhone. Buying Motorola is an acknowledgement on Google’s part that it must control the experience from software to hardware if it hopes to unseat Apple.

A summit of leaders on Feb. 4 produced no breakthrough, with Germany and France introducing new proposals for boosting competitiveness across the zone, prompting renewed disagreement among states. Another summit is due to be held after March 9 to sustain momentum towards a deal, with the complete package expected to be finalised at another summit on March 24-25 in Brussels. Below are ideas that have been discussed formally or informally and could be included. Some measures face strong opposition from Germany and appear unlikely to make it.

INCREASING THE EFFECTIVE LENDING CAPACITY OF THE EFSF

There is a strong chance of this step being adopted. The nominal lending capacity of the European Financial Stability Facility, the euro zone bailout fund, is 440 billion euros, but because of a system of guarantees to secure a triple-A credit rating, the special purpose vehicle has an effective lending capacity of only around 250 billion euros. The European Commission, France, Germany and others agree that the effective lending capacity should be boosted to the full 440 billion and talks are focusing on how to do that. The idea of raising the EFSF's overall size above 440 billion euros was rejected by euro zone ministers on Jan. 17.

HOW COULD THE EFSF'S CAPACITY BE INCREASED?

Lifting the EFSF's effective capacity could require euro zone states to increase their guarantees, forcing some governments to seek fresh approval from their parliaments. This could be politically tricky in countries such as Germany where public opinion is against bailouts of countries that have been overspending or not kept budgets in check. Berlin has indicated that instead, euro zone countries with a rating below the top notch could inject cash into the EFSF, making up for their lack of a triple-A grade. If the 11 non-AAA countries in the euro zone injected cash, the fund would no longer need cash buffers to secure its rating and could therefore lower its interest rate. But non-AAA countries are not keen to spend cash, so the end-result could be a mix of both options, euro zone sources have indicated.

Five cajas failed Europe-wide stress tests on banks last year. The Bank of Spain has forced them into a round of mergers, reducing their number from 45 to 17 last year. High levels of bad property loans at the cajas are seen as a major risk for Spain as it slashes its budget deficit to stave off fears it will need an Irish or Greek-style rescue from the European Union and International Monetary Fund. Estimates of the cost of recapitalising the savings banks range from €17bn (£14.4bn) to €120bn, with consensus falling in the €25bn to €50bn range, according to Reuters. Economists say Spain could afford that level of rescue without seeking outside aid.The banking sector has so far set aside €88bn to cover losses on total loans of €439bn to real estate and construction. Spain's borrowing costs have soared amid worries that the sovereign debt crisis that forced Greece and Ireland to seek bailouts will spread to Portugal and then Spain. A budget deficit of 9.3% of GDP in 2010 and stagnant growth have added to the worries, though the government is hitting deficit reduction targets and pledges pension and labour reform shortly. Analysts welcomed the promise of caja recapitalisation. "This underpins hopes that Spain is now on the right track," Commerzbank strategist David Schnautz told Reuters.
