The implications of recent stock market volatility in the United States, combined with slowing job growth and rising unemployment, are causing a panic and triggering discussions about an inflection point. The signs of a recession are rattling the market’s shared hope for a soft landing.

Only through steadfast multilateral policy coordination and flexible, effective measures can global financial markets weather the storm safely and achieve stability and development.

Financial markets today are thriving. The Dow Jones industrial average, the S&P 500, and the Nasdaq composite index have all reached record highs lately, with emerging-economy financial markets also performing strongly. But digital currencies could further destabilize an already-tenuous leverage- and liquidity-based system.

The bubbles in both finance and property are growing too big. The ordinary real economy is increasingly unable to bear the over-expansion of finance and property of the past 10 years. And NASDAQ is the most precarious bubble of all.

Chinese President Xi Jinping defended his government’s economic stewardship and said that China’s slowing growth and market fluctuations won’t deter needed reforms.

The lens of government intervention in China has led foreign observers to misinterpret some of the most important developments this year in the foreign exchange market and the stock market.

Moderating growth rates in the range of 5-7% per annum reflect the higher per capita income level and the changing growth paradigm in China.

Tectonic shifts are occurring in the economy, financial markets, geopolitical strategy, and social policy. The ultimate test may well lie in managing the exceedingly complex interplay among these developments. Is China’s leadership up to the task, or has it bitten off too much at once?

As the Fed is paving way for the first rate hike in a decade, the world economy prepares for the greatest shift of capital flows in five years. Recent market turmoil in the U.S. and China heralds the transition.
