Yuan Strength Yields 16% Return... When Is the Right Time to Enter the Chinese Stock Market? [Weekend Money]

Despite the Sluggish Chinese Stock Market, the Yuan Continues to Strengthen
The Limits of 'Interest Rate Parity' in Explaining This Phenomenon

While Asian stock markets, including Korea, Japan, and Taiwan, continue their rally, Chinese investors remain unenthusiastic. However, the recent persistent strengthening of the yuan has provided some relief.

As of June 1, the exchange rate for the yuan against the won was 222.3 won per yuan, marking a 16.3% appreciation over the past year. This means that Korean investors who held only yuan for the past year would have gained a 16% return. With constant news highlighting the struggles of the Chinese economy, one may wonder why the yuan has strengthened so significantly.

Yuan Strength Not Explained by 'Interest Rate Parity' Theory

Choi Seolhwa, a researcher at Meritz Securities, stated in a report published on June 4, "The yuan’s current surge is difficult to explain with the typical logic of interest rate parity. Instead, this trend is primarily driven by a rapid increase in demand for foreign currency exchange rather than interest rate differentials."

According to the interest rate parity theory, capital flows to where it can earn higher interest. If U.S. interest rates are higher than those in China, investors buy dollars and sell yuan; if the reverse is true, they buy yuan. In other words, the currency of the country with higher interest rates strengthens.

However, the current situation is a complete reversal of this rule. Chinese interest rates have fallen, while U.S. interest rates have risen. According to the textbook, the yuan should have weakened, yet it has strengthened instead.

The Cause Lies in China's 'Accumulated Dollars'

Researcher Choi identified supply and demand as the key factor behind the yuan's recent appreciation.

During the two to three years of the yuan’s weakness, Chinese exporters received dollars but did not convert them into yuan. Chinese companies, expecting further yuan depreciation, saw no reason to exchange their dollars. Some estimates suggest that up to 2.5 trillion dollars accumulated in this way.

When the yuan began to rise, companies started selling their dollars and buying yuan en masse. This explains why foreign currency settlement volumes surged by 36% year-on-year between January and April this year. According to researcher Choi, it was not interest rate differentials but the sudden conversion of previously held dollars that was the real cause.

Is Now the Time to Invest in China Amid Yuan Strength?

In the past, a strong yuan was often seen as a positive signal that attracted global capital inflows. However, the current bout of yuan appreciation has yet to result in any meaningful inflow of foreign capital.

This is because the current strength of the yuan is primarily due to supply and demand dynamics, not an improvement in economic fundamentals. Once the accumulated dollars are exhausted, the upward pressure on the yuan will weaken. Since corporate currency exchanges have already increased liquidity within China, the People's Bank of China has little justification to lower interest rates further. Many analysts recommend caution until there are clear signs of a genuine improvement in China’s economic fundamentals.

Researcher Choi projected, "The prerequisite for a rebound in the Chinese stock market is an improvement in corporate earnings. Once fundamental improvements are confirmed, yuan appreciation will act as a catalyst, and, together with foreign capital inflows, will create strong upside risk for the Chinese stock market."
