South Korea shares surge on strong factory data as China retreats

On the first trading day of March 2021, South Korean stocks climbed 1.5 percent while most of Asia's emerging markets moved sideways. The Seoul market had reopened after a public holiday, and the strength came on the back of factory data that signaled genuine economic momentum. In February, South Korean manufacturing had expanded at its fastest rate in nearly eleven years. Exports, meanwhile, had now grown for four consecutive months running—a steady drumbeat of outbound demand that suggested the world's fourth-largest Asian economy was finding its footing after the pandemic's disruption.

The broader regional picture was more muted. Taiwan, also reopening after a holiday closure, gained just over 1 percent. Malaysia rose half a percent, though rubber glove makers—companies that had benefited enormously from pandemic demand—dragged on sentiment. The Philippines and Indonesia each edged up a quarter percent. Currencies held tight ranges as the U.S. dollar strengthened on signs that America's own recovery was accelerating, buoyed by optimism around a COVID-19 relief package making its way through Congress.

But there was a counterweight to this cautious optimism. U.S. Treasury yields had spiked over the preceding month, driven by rising inflation expectations and the prospect that the era of cheap money might be ending. That shift had begun to unsettle investors at a delicate moment in the global recovery. Analysts at OCBC noted the tension plainly: sentiment would likely remain choppy as markets absorbed the implications of higher yields. Yet they saw reason for longer-term confidence. Vaccination campaigns were advancing, central banks remained supportive, and the default posture among investors still favored risk-taking assets.

China presented a different story. The Shanghai Composite index fell about 1 percent, while blue-chip stocks dropped 1.1 percent. The yuan weakened slightly. Behind the numbers lay a regulatory concern that had begun to preoccupy Beijing's financial authorities. The country's top banking and insurance regulator had expressed worry about the risk of asset bubbles forming in foreign markets, particularly as capital flowed outward from China. Officials were studying measures to manage those inflows—a signal that policymakers were watching the movement of money with some care. The timing mattered. China's parliament was set to convene on Friday, where the government would chart its economic course for the coming years and unveil a five-year plan. Any capital controls or restrictions announced then could reshape how money moved through the region.

Meanwhile, the Reserve Bank of Australia, which had already intervened the previous week to buy bonds in response to rising U.S. yields, reaffirmed its commitment to keeping interest rates at historic lows. The message from central banks remained consistent: support would continue. Yet the market's mood reflected an underlying uncertainty—the old playbook of stimulus and low rates was being tested by inflation signals and the possibility of a different monetary era ahead. South Korea's factory data offered a concrete reason for optimism about the real economy. But the movement in yields and the regulatory caution in China suggested that the path forward would not be smooth.
