China Warns: Defending Yuan at 7 per Dollar Won’t Come Cheap

October 13, 2025

China’s Central Bank Adviser Warns of Consequences of Yuan Falling Below Key Level

The People’s Bank of China (PBoC) is closely monitoring the exchange rate of the Chinese yuan and has a significant interest in maintaining its stability. This is according to Sheng Songcheng, an adviser to the PBoC, who made these comments at a forum held in Shanghai on Saturday.

While speaking at the event, which was organized by the financial media outlet WallStreetcn.com, Sheng emphasized that if the yuan were to fall below a key level of 7 per dollar, attempts to stabilize its exchange rate would become increasingly costly for China’s foreign exchange reserves. He explained that stabilizing the rate at this crucial juncture requires significantly less from China’s reserves when the yuan is valued at around 6.7 or 6.8 per dollar.

However, should the currency continue to fall below the 7-per-dollar mark, the costs for supporting its stability would increase steeply. Sheng explained that if market expectations of a rapid devaluation were high enough, the value of China’s foreign exchange reserves would then be inadequate in preventing a subsequent drop in the yuan’s value.

To mitigate this problem, it seems that China will prioritize stabilizing the exchange rate over pushing for currency reform or internationalization of the renminbi (RMB). Stabilizing the yuan is considered essential, especially in light of its recent nearly 7% loss of value against the dollar since the beginning of the year.

Key Concerns Behind China’s Focus on Yuan Stability

=====================================================

China’s decision to maintain a strong emphasis on stabilizing the exchange rate may be driven by several key factors. Firstly, it may be seen as vital for maintaining investor confidence and avoiding sharp capital outflows that could strain the country’s foreign exchange reserves.

Additionally, China might perceive keeping its currency stable as a crucial step in preserving economic stability at this point in time. Sheng stressed that defending an exchange rate entails investing a considerable amount of resources to ensure market expectations are not met by a fast devaluation of the yuan.

To better grasp just how substantial these costs could be, let’s examine some specific figures and considerations surrounding China’s efforts.

The Psychological Importance of 7 Per Dollar


For many, the 7-per-dollar level has become a critically important benchmark in assessing the yuan’s exchange rate. Policymakers recognize the potential for destabilization beyond this point, which could be triggered merely by speculation or heightened market uncertainty.

In fact, should the yuan fall below this benchmark value, it may attract additional selling pressure from both domestic and international investors, further exacerbating downward trends. Given these risks, China’s central bankers might consider investing significant financial resources in stabilizing the currency to mitigate possible losses and safeguard against such potential destabilization.

Assessing the Pros and Cons of Each Option


Stabilizing an exchange rate presents several complexities for policymakers worldwide. The costs involved could range from modest to severe, depending largely on how well market expectations are factored during the process of defending a specific value of the currency.

A sharp fall below 7 may create even more daunting challenges for keeping investor confidence high and supporting growth within the Chinese economy over time.

China’s Options Going Forward


As we move forward with assessing China’s options in maintaining stability within its foreign exchange market, let’s briefly outline some critical areas to watch: stabilization through spending on reserves, promoting stability through monetary policy tools, or using other less direct means like influencing expectations via interest rates changes and market interventions.

Implications for Investors


Investors worldwide are closely observing China’s moves in this situation for several reasons:

  • To better grasp the potential impact these actions may have on global markets as a whole
  • Due to rising concerns about currency volatilities within emerging economies such as China and implications for investment decisions at large.

By understanding how policymakers balance competing priorities like stabilizing the exchange rate against more long-term objectives, investors can gain valuable insights into navigating associated risks or opportunities arising from these actions.

The Global Context of Yuan Volatility

=========================================

A rapidly weakening yuan increases pressure on other major currencies to hold steady against it, a situation that carries its own set of complications for financial markets and the overall health of emerging economies worldwide.

Beyond China itself, policymakers in other developing countries may wonder if this unfolding situation could potentially set off new waves within emerging currency movements across more developed global markets.
