It is easy to be downcast about the state of global trade. It has faced stiff headwinds in recent years: in 2016, for the first time in 15 years, it grew more slowly than the world economy. Regional and global trade deals are going nowhere, slowly. And America's new president has promised to protect his country from trade-inflicted "carnage".
Amid all this gloom, optimism seems foolhardy. But in Asia's export dynamos, trade is picking up steam. In January, Chinese exports rose year-on-year for the first time in 10 months; South Korean shipments have increased for three months in a row. Surveys reveal strong export pipelines in Japan, Singapore and Taiwan. Healthy order books for Asia's manufacturers normally bode well for global trade and indeed the global economy. It is too soon to declare a definitive upturn in global trade, but it looks like more than a blip.
The simplest explanation for the rebound is that global demand is itself on solid ground. Global growth is still slower than before the financial crisis of 2008, but is heading in the right direction. Both the IMF and the World Bank think it will speed up a bit this year. Investors have turned more bullish: the MSCI all-world index, which covers 46 different markets, hit a record high this week. The rebound in Asian exports is more reason for bullishness.
Structural changes may also be at play in Asia. A much-cited factor behind the slowdown in global trade in recent years has been China's tightening grip on complex supply chains. As more production takes place inside a single country, fewer cross-border transactions are needed to produce final goods. Yet this consolidation within China is starting to meet more friction.
There are also good reasons to restrain the optimism. The rebound in exports from Asia's commodity producers such as Indonesia and Malaysia is mainly the result of higher prices for oil and metals.
Growth in their trade volumes has been much slower. For Asia's high-tech economies, the rebound's durability hinges on the fickle tastes of consumers. Both Samsung and Apple are expected to launch shiny new gadgets this year. Semiconductor makers around the region have gone into overdrive in anticipation. If demand falls short of expectations, exports of electronics will quickly dive again.
