RSIRelative Strength Index (14)

What it is

RSI is a 0–100 momentum gauge of recent gains versus losses. Above 70 is overbought (stretched), below 30 oversold (beaten down), and 50 is the neutral line.

Where it stands now

USD/CNY's RSI is 17.

Possible move ahead

A turn back above 30 confirms a bounce.

Foreign exchange markets are closely monitoring the USD/CNH pair as a recovery in the US Dollar and a tick upward in US Treasury yields push exchange rates higher. Despite these bullish impulses for the Greenback, the People's Bank of China continues to prefer a measured pace of Renminbi appreciation. Strategists Sim Moh Siong and Christopher Wong at OCBC highlight that while daily charts maintain a mild bearish momentum, tentative oversold signals could spark a modest rebound. At the same time, renewed US geopolitical pressure surrounding Iranian oil imports introduces secondary sanction risks that could heighten two-way volatility for the Chinese currency.

PBoC Currency Fixings Signal Controlled Appreciation Path

Chinese central bank officials are actively managing currency movements by maintaining a sizeable gap between official daily fixings and market expectations. This policy stance indicates that policymakers remain cautious about allowing rapid RMB strength that could undermine export competitiveness. Live market data shows USD/CNY trading at 6.71, down 0.17 percent from its previous close of 6.72, within a 52-week trading range of 6.71 to 7.19. The measured fixing strategy underscores Beijing's intention to absorb external US Dollar fluctuations while maintaining tight oversight over capital flows.

Geopolitical Risks from Iranian Crude Purchases and Secondary Sanctions

China's position as a primary buyer of Iranian crude oil exposes its financial system to escalating US geopolitical measures. While current currency impacts remain contained as long as enforcement stops short of directly targeting major Chinese banks, any broadening of secondary sanctions to Chinese enterprises or financial intermediaries could severely weigh on market sentiment. Such geopolitical friction threatens to disrupt trade settlement channels and introduce sharper two-way exchange rate fluctuations.

Cross-Currency Shifts in GBP, EUR, and Federal Reserve Outlook
