Yen and Yuan Watch: USD/JPY and USD/CNY Daily — 2026-09-10
The Japanese yen has surged to its highest level since February, surpassing previous intervention peaks as traders bet on further Bank of Japan (BoJ) rate hikes and potential coordinated action with the US. Meanwhile, the People's Bank of China (PBoC) actively managed the yuan's strength, setting daily fixings weaker than market expectations to slow the currency's appreciation against the dollar.

Yen Surges Past Intervention Peaks on BoJ Hike Bets
On September 7, the yen strengthened significantly, reaching a one-month intraday high and surpassing the levels seen after the coordinated Japan-US intervention earlier this year. USD/JPY fell to the 154 yen range, its strongest level since February 2026, driven by growing speculation that the BoJ will accelerate its rate-hiking cycle. This move has triggered a rapid unwind of yen carry trades, with investors repatriating funds from higher-yielding assets back into Japan.
PBoC Sets Weaker Fixings to Curb Yuan Strength
The People's Bank of China (PBoC) set the USD/CNY reference rate for Tuesday, September 8, at 6.7804, which was weaker than the Reuters estimate of 6.7104 and the prior day's fixing of 6.7795. This "weaker-than-expected" fixing was a deliberate signal to slow the yuan's recent rally, which had seen the offshore yuan (CNH) briefly hit its lowest level since February 2023. The move indicates Beijing's desire to maintain export competitiveness by preventing excessive yuan appreciation.
No Immediate Intervention Confirmed Despite Volatility
Despite the sharp yen appreciation, Bank of Japan accounts data released on September 3 suggested no major foreign exchange intervention occurred on that day. The volatility was attributed to traders recalibrating their expectations for BoJ policy rather than direct Ministry of Finance (MoF) market operations. However, US Treasury Secretary Scott Bessent reiterated on September 3 that he believes Japanese authorities remain ready to act if necessary to support a stronger yen, keeping intervention risk elevated.
Yuan Emerging as New Carry Trade Funding Currency
As the yen strengthens and becomes more volatile, strategists note that the Chinese yuan is gaining attention as an alternative funding currency for carry trades. With the yen's cost of carry rising due to BoJ tightening expectations, investors are looking toward the yuan, which remains relatively stable due to PBoC guidance, to fund positions in higher-yielding markets. This shift could dampen future yen volatility but adds complexity to global liquidity flows.
Local view
Nikkei (Japan): Local media highlight that while the yen has appreciated past the 154 level, the focus has shifted from "intervention" to "policy divergence." Reports indicate that the uncertainty surrounding the timing of the next BoJ rate hike is causing "twitchy" trading behavior, with some analysts warning that the current yen strength may be fragile if US inflation data remains sticky.
Investing.com CN (China): Chinese financial platforms report that the PBoC's "weaker-than-expected" fixing is being interpreted by local exporters as a supportive signal. Commentary suggests that the central bank is balancing the need for internationalization of the yuan against the immediate pressure on manufacturing margins, with offshore CNH rebounding after the initial drop below 6.70.
Context & numbers
- USD/JPY: Traded near 154.00 on September 7-8, down from over 160 in late August. This represents a ~4% appreciation in under two weeks.
- USD/CNY Fixing: Set at 6.7804 on September 8, compared to a Reuters estimate of 6.7104.
- USD/CNH Spot: Briefly touched 6.7059 before rebounding following PBoC guidance.
- Intervention History: Japan spent a record 15.4 trillion yen ($98 billion) between July 30 and August 2026 to boost the yen in the previous intervention wave.
On the radar
- BoJ Meeting Signals: Market participants are watching for any hawkish language from BoJ Governor Kazuo Ueda regarding future rate hikes, which would further support the yen.
- PBoC Daily Fixings: Continued "weaker-than-expected" fixings will be monitored closely to gauge Beijing's tolerance for yuan strength. Any shift toward stronger fixings could signal a change in policy stance.
- US Inflation Data: Upcoming CPI releases will be critical; hotter-than-expected data could reverse some of the yen's gains by reducing expectations for Fed cuts, thereby widening the US-Japan yield differential again.
