When Should A Country Abandon Its Own Money?

Enough already with the krona?

Iceland is a tiny nation in a big financial mess. It's still recovering from the aftermath of the 2008 global economic crisis, which caused a domestic banking collapse.

Its currency, the krona, is also in really bad shape. That's led Icelanders to pose an existential currency question: Should they abandon the krona?

One key problem is size. Iceland has about as many people as Staten Island, so there just aren't that many people on the planet who need to use the krona.

"There are more people using Disney dollars," says Arsaell Valfells, an Icelandic economist.

The story of how the U.S. wound up with the income tax is the story of two wars, a Supreme Court justice on his death bed, and Donald Duck.

It's also the story of how the government overcame three obstacles.

There is an advantage to strengthening the currency for people in China: It makes their imports cheaper. A clerk counts bank notes in a bank in Nantong, east China's Jiangsu Province.

China's central bank is sitting on a giant pool of U.S. dollars. It's the world's biggest holder of foreign reserves, worth over $3 trillion at last count.

All that money has piled up because every year, China exports more than it imports; it runs a trade surplus.

There are lots of reasons for China's trade surplus. In the past few decades, China has built an amazing manufacturing ecosystem. It's become the factory to the world.

From Cell Phones To Cigarettes: The Long Arm Of The Chinese Government

How many government-owned businesses do you see in this picture?

The streets of Beijing and Shanghai feel like an entrepreneurial free-for-all, full of mom-and-pop stores and street vendors selling snacks and cheap toys.

But when you pull back the curtain, you see a different picture: a country where the government still controls huge swaths of the economy.

When you're in China, there's a good chance you're doing business with the government every time you:

Is China An Economic Miracle, Or A Bubble Waiting To Pop?

This can't go on forever.
Jacob Goldstein NPR

China's economy sailed through the financial crisis unscathed — at least in the short run.

When the global crisis hit, the country's government-owned banks started lending out lots more money. The money came largely from the savings accounts of ordinary Chinese people. It went largely to finance big construction projects, which helped keep China's economy growing.

In 1978, the farmers in a small Chinese village called Xiaogang gathered in a mud hut to sign a secret contract. They thought it might get them executed. Instead, it wound up transforming China's economy in ways that are still reverberating today.

The contract was so risky — and such a big deal — because it was created at the height of communism in China. Everyone worked on the village's collective farm; there was no personal property.

"Back then, even one straw belonged to the group," says Yen Jingchang, who was a farmer in Xiaogang in 1978. "No one owned anything."
