The year in business: 2010

By Martin Webber Business Editor, BBC World Service

Over 600 estates lie unfinished across Ireland, where land is among the most expensive land in Europe

You have to go back four years to 2006, to the find economic policymakers in the West in an upbeat, confident mood.

Since then they have been battered by waves, ranging from collapsing banks to frozen financial markets, culminating in 2009 with the first drop in world annual output since the 1930s depression.

During 2010 there has been a return to overall global growth.But sceptics say the world's politicians are simply papering over the cracks, and the big fault lines in the global economy remain.

China's big trade surplus and fixed currency system appear to be unreformed, Americans continue to spend money they do not have, while in parts of Europe the situation is still worsening with the International Monetary Fund (IMF) being called in to provide emergency loans, first in May to Greece, and then to Ireland.

Supporters of the banking status quo insist that the complex multi-purpose banks and their financial derivatives trading desks are necessary to ensure that cash is invested in the most productive places in the world.

“If the euro fails, Europe fails. ” Angela Merkel German Chancellor

That particular argument wilts somewhat if you travel to Ireland. While many parts of the world desperately need basic infrastructure, Ireland simply has far too much of it. Vast so-called ghost estates built in the boom times now lie empty.

According to reporter Henry McKean, "Ireland won the lotto and everyone wanted a property portfolio". Houses were built in isolated parts of the country. "County Leitrim in North West Ireland has 21 ghost estates and an oversupply of 401%," Mr McKean says. The money to fuel Ireland's property boom came mostly from the banks. But were they solely responsible for the rush to build new homes across Ireland? Councillors and planners are to blame, but you also have to acknowledge that there was blind greed on behalf of builders and landowners around the country.

The blame game

Critics of Europe's single currency system say the euro was at least partly to blame. Ireland was unable to dampen its property boom by setting its own interest rates because its rates are set by Europe's Central Bank, which has to consider conditions across 16 different nations. Some wondered if the answer might be to allow the stronger euro economies to split from the weaker ones, allowing countries such as Ireland more economic freedom, while many in Germany became increasingly angry that they were footing much of the bill to rescue Ireland, as well as Greece which was bailed out earlier in the year.

But Germany's leader, Chancellor Angela Merkel, reiterated her commitment to the euro. "If the euro fails, Europe fails. But if we avert this danger, the euro and Europe will come out stronger than before," she declared. The UK coalition government announced a stringent budget to tackle the debt crisis. Even in the boom times, most governments in Western Europe spent more than they collected in taxes. Now, after a severe recession, public finances everywhere are stretched and in the UK, a new Conservative-Liberal Democrat coalition government announced sharp spending cuts in the coming years. The age of austerity had arrived.

Banking on reform

But what about reforming the system that produced the boom and bust?

The big banks were targeted by US President Barack Obama in January as he upped the rhetoric by announcing a new levy to claw back money from institutions which had been bailed out during the financial crisis. "My commitment is to recover every single dime the American people are owed and my determination to achieve this goal is only heightened when I see reports of massive profits and obscene bonuses at some of the very firms who owe their continued existence to the American people," he said.

Then bank shares tumbled after President Obama turned for advice to the former US central bank boss, the 83-year-old Paul Volcker. Goldman Sachs is not interested in America, Goldman Sachs is interested in Goldman Sachs” Peter Morici University of Maryland

The President embraced Mr Volcker's view that banks holding cash deposits from ordinary Americans should be banned from so-called proprietary trading, where the banks take big bets in financial markets. "I'm proposing a simple and common sense reform, which we're calling the Volcker rule," President Obama announced."Banks will no longer be allowed to own, invest or sponsor hedge funds, private equity funds or proprietary trading operations for their own profit, unrelated to serving their customers."Some reform of the banks was eventually passed in Congress with the Dodd-Frank Wall Street Reform Act, although the Volcker rule was watered down.

So did the reforms go far enough? Peter Morici at the University of Maryland thinks not and says that "until we separate the banks from the investment banks, so that banking is again banking, as opposed to trading, the banks are going to be much more interested in trading than banking, simply because they can make a lot more money that way."Goldman Sachs is not interested in America, Goldman Sachs is interested in Goldman Sachs."“If you are looking for aristocrats that should be beheaded, they are probably on Wall Street” Peter Morici University of Maryland

But Goldman Sachs has clever people and are doing very clever things and at the end of the year, they make a profit. So what is wrong with that?"Well, they did clever enough things to thrust the entire global economy into the great abyss," says Mr Morici. "Bank of America and Morgan Stanley made profits every day on trading in the last quarter - they didn't have a negative day," he says. "Unless you think traders are perfect there is something wrong with the information that they are getting," he maintains.

However, when somebody gains, somebody else is losing.

"Americans are losing. The ordinary stock holder is losing. They are not creating wealth on Wall Street, they are trading on it," Mr Morici asserts. "If you are looking for aristocrats that should be beheaded, they are probably on Wall Street, though I wouldn't do it using a guillotine, I'd just take their toys away."

Eternal hope

The spotlight was diverted from the big banks for a while when an explosion at a BP oil rig in the Gulf of Mexico led to 11 deaths and created the biggest offshore oil spill in US history. BP set aside $40bn to cover the cost. Google had its own issues with Beijing - this time over censorship. It moved its China web search to its Hong Kong site in March.

And the hopes of the US seed firm Monsanto to introduce genetically modified crops into India were dashed, when the Indian government blocked the plan after protests from environmental groups and some scientists.

The US stock market overall rose around 10% in the past year, although historically American share prices have made no overall gains at all in the past 11 years. By contrast, gold has soared over that period, leaping from $300 an ounce to $1,400, with this year's rise for gold being 25%.

There is always money to be made somewhere in the global economy.
