China the world's largest economy

China’s GDP in 2009 is about $5 trillion whilst that of the US is $14 trillion – nearly 3 times larger. China overtook Japan to be the 2nd largest economy this year. So, when will China overtake the US to be the world’s largest economy?

The relative GDP figures of 2 countries depend not just on the growth rate. It is also impacted by things like inflation and currency exchange rate. China, which traditionally has a higher inflation rate, will get a boost on its GDP from inflation. Similarly, a strengthening Yuan will help bolster its value of goods and services produced.

In the last decade, the real GDP growth averaged 10.5% for China and 1.7% in America; inflation averaged 3.8% and 2.2% respectively. Since 2005, the Yuan has appreciated an average of 4.2% annually.

Extrapolating from the past, conservatively, we assume an average growth rate over the next decade of 7.5% for China and 2.5% for the US, inflation rate of 4% and 1.5% respectively and the Yuan gaining 3% per year, China should pass the US as the biggest economy in the world by 2020. If, however, China’s growth falters to 5%, then the overtaking date would be 2022 – a mere 2 years later.

So, it is no more a question of whether China will overtake the US as the world’s biggest economy. Rather, it is a matter of when only.

Stewed in the Irish juice

Up to the late 80s, Ireland was a backwater economy – with high unemployment & huge government debt. In 1987, the unemployment rate was 18 % and the government’s debt was 120 % of the GDP. It was largely an agricultural economy.

Then the government pushed through dramatic economic reforms. Corporate taxes and business regulations were lowered. This opened the economy to the rest of Europe and attracted a lot of biotechnology and high tech investments. The country prospered. Its per capita income growth rate shot to 6 % from the historical rate of 3.5 %. Similarly, its GDP growth touched a figure of 10 %.

Wages rose and with it prices. Housing became a good investment. The banks borrowed huge amounts from the international wholesale market and loaned it to the domestic housing market. The feed of easy liquidity engendered a huge housing boom and it snowballed. House prices, construction company stocks, land prices and all things related to construction skyrocketed. By late 2006, the average new house costs 10 times the average earnings.

The boom peaked in late 2006. By the middle of 2007, unsold housing units began to accumulate. Banks began to feel the heat. In late September 2008, a run started in the wholesale markets on Anglo Irish Bank. It was quite clear that the domino effect or contagion would take hold. The government took the unusual step of guaranteeing all deposits and senior debt in the six Irish banks, nationalized Anglo Irish and invested 3.5 billion Euros in two other banks. And that is the start of the Irish economic decline.
