Since the onset of the economic crisis, the U.S. Treasury and the Federal Reserve have taken unprecedented actions to support domestic economic recovery and address the weight of national debt. This has involved injecting trillions of dollars into the market, prompting a notable depreciation of the dollar index. Throughout the year, the index has seen a significant drop, eventually plummeting below the key 90 mark. As more stimulus measures are anticipated in the future, further declines in the dollar index appear likely, raising questions about the financial stability of the U.S. currency.

In striking contrast, the Chinese yuan has been on a steady upward trajectory since July 2020, achieving a two-and-a-half-year high. This remarkable rise signifies a robust recovery in the Chinese economy, particularly in the context of international capital flows, which seem to favor the yuan over the dollar. The efficiency with which China has managed its pandemic response has resulted in clear economic advantages, while the U.S. grapples with rising daily confirmed cases and fatalities, suggesting an extended recovery period. Consequently, more investors view the yuan and yuan-denominated assets as attractive opportunities.

This significant divergence between the two currencies raises pressing questions regarding the implications for China’s foreign trade and the broader impact on its massive foreign exchange reserves, especially concerning U.S. Treasury bonds. To understand these dynamics, it is essential to analyze the nuances of the currency fluctuations and their consequences.

While it is essential to acknowledge that these developments have certain negative implications for China, the overall impact is somewhat limited. An initial observation reveals that long-term shifts in the yuan's exchange rate have not significantly disrupted foreign trade. However, short-term volatility can wreak havoc on trade revenues. Over the long haul, the periods of considerable appreciation of the yuan have corresponded with growth phases in China’s foreign trade, suggesting that the connection is not as pronounced as many believe. Yet, swift short-term appreciation of the currency can disrupt immediate trade income and contribute to a decline in long-term orders, illustrating potential adverse effects.

Fortunately, despite the yuan's appreciation, the production capabilities in European and American markets have yet to recover, maintaining China's status as the primary exporter globally. Thus, even with a rapid rise in the yuan, the impact on exports may not be as severe as one might assume. The relative dearth of competition from other countries allows Chinese goods to remain in demand despite currency fluctuations.

Additionally, the appreciation of the yuan does exert some pressure on China's debt landscape. In response to the economic downturn, China has implemented substantial fiscal stimulus measures, leading to a corresponding increase in debt loads. As the yuan strengthens, the pressures associated with this debt—particularly for local governments and private enterprises—become more pronounced. The diminishing returns from U.S. Treasury yields in the context of dollar depreciation further complicate this landscape, as the interest expenses on yuan-denominated debt may surpass the returns on dollar-denominated assets. This divergence necessitates proactive measures from Beijing to mitigate fiscal burdens.

The ongoing depreciation of the dollar could also enable the U.S. to purchase Chinese goods at reduced prices, benefiting American economic recovery but posing challenges for China's growth trajectory. Rather than viewing the dynamics exclusively through the lens of advantage and disadvantage, it is crucial to grasp the implications of the yuan's appreciation on the Chinese economy in its entirety.

Another angle worth examining pertains to the cost of imported raw materials. As the first major developed economy to achieve positive economic growth amid the crisis, China has displayed substantial demand for raw materials, which has driven prices, such as those for iron ore, significantly upward. While commodity prices dipped during the pandemic, recent surges in demand have positioned the yuan’s appreciation as a mechanism for alleviating raw material costs. This development could mitigate import-driven inflation and help control production costs across China.

In sum, while the yuan's strengthening does present certain short-term challenges, the broader economic implications would not inflict severe damage on the larger economic framework. Additionally, the allure of yuan-denominated investments could bolster foreign investment, suggesting a nuanced balance of benefits and drawbacks.

Yet, the press for de-dollarization in the face of rapid dollar devaluation prompts calls for China to divest from U.S. Treasury bonds. Amid these challenges, a faction of opinion argues that divesting from American debt would safeguard China from economic exploitation. Nevertheless, it is crucial to approach this notion with caution. Although China aims to decrease its reliance on the U.S. dollar and diminish its Treasury holdings over the long term, the immediate horizon does not favor drastic divestment.

The supremacy of the dollar remains largely intact, despite the Federal Reserve's aggressive monetary stance leading to reduced appeal for investors. While this trend signifies the potential for future shifts, the current global financial landscape still relies heavily on U.S. dollar-denominated transactions. Hence, maintaining a portion of foreign exchange reserves in dollar assets and American securities remains a prudent approach that cannot be forsaken at present.

Moreover, the rapid export of Chinese goods to the U.S. serves as mutually beneficial economic reinforcement for both nations. This influx of dollars generates a need for some of those funds to be converted into Treasury securities, binding the two economies together. Thus, despite U.S. policy maneuvers aimed at diluting debt through dollar depreciation, the prevailing dollar dominance suggests that the time to significantly reduce American bond holdings has yet to arrive.

In a broader context, even amid the current stage of dollar depreciation and its implications, it does not pose an existential threat to China’s economic framework or foreign reserves. Ironically, the dollar's decline could foreshadow its eventual erosion of dominance, presenting opportunities for a more diversified currency system that aligns with China's broader strategic interests.
