Japanese Yen: Joint intervention reshapes FX dynamics – Commerzbank

FXStreet Insights Team FXStreet

Commerzbank analyst Michael Pfister examines recent joint US–Japan intervention to support the Japanese Yen. He notes confirmation that US authorities helped Japan and that further actions are possible, but constrained by IMF rules. Pfister argues the Yen is heavily undervalued, explores motives linked to US Treasuries and JGBs, and warns markets to brace for additional interventions.

US–Japan action and yen valuation

"This morning, official confirmation finally arrived that the US had lent Japan a hand with its interventions to strengthen the yen for the first time in many years, something that had been clear since Friday at the latest. Officials have emphasised that they are ready to carry out further interventions, although Thursday's intervention alone is estimated to have been the largest single-day intervention to date."

"The yen has been significantly undervalued for many years. According to OECD purchasing power parity, it is currently more than 60% undervalued against the US dollar. By way of comparison, the euro is undervalued by about 29%."

"I suspect that the US was more concerned that US Treasuries might be sold off. Japan could have sold them to prop up the yen with the US dollars received, which would tie in with reports that Japan might make greater use of the Fed’s repo facility (i.e. deposit USTs there as collateral in exchange for cash)."

"However, if Japan intervenes again in the coming days, the Ministry of Finance will have effectively used up all its options until November in order to retain that status."

"Until then, market participants should brace themselves for possible interventions later in today's trading session."

AUD/USD gains traction near 0.7100 as the post-Fed USD rally pauses

AUD/USD finds fresh buyers and retakes 0.7100 in the Asian session on Thursday as the US Dollar pauses its hawkish Fed-inspired rally to its highest level since late July. However, RBA rate-hike bets and hopes for US-Iran diplomatic efforts lift risk sentiment and support the risk-sensitive Australian Dollar and the major.

USD/JPY reverses a dip below 156.00 as focus shifts to BoJ

USD/JPY is reversing a brief dip below 156.00 in the Asian session on Thursday, looking to snap a three-day winning streak to a nearly two-week top set the previous day. The US Dollar pauses following the post-Fed rally to seven-week highs, while a more hawkish repricing of the BoJ's policy normalization path supports the Japanese Yen. This keeps the pair's upside limited, with the focus now shifting to the BoJ policy decision due on Friday.

Gold pops to weekly highs near $4,400

Gold climbs sharply and clinches fresh weekly peaks around the $4,480 zone per troy ounce on Thursday. The precious metal’s bounce leaves behind three daily declines in a row and follows the marked retracement in the US Dollar as well as another negative performance of crude oil prices.

Crypto Today: Bitcoin, Ethereum, XRP stabilize defying macro headwinds and ETF outflows

Bitcoin is showing resilience, trading up above $76,000 on Thursday. The uptick follows the US Fed decision that hiked interest rates the day before. Meanwhile, ETH gains momentum toward $2,500, suggesting the return of bulls as macro headwinds settle.

The Fed hawkishly hiked rates

The Fed proceeded with its first rate hike since 2023, as was widely expected. It should be noted that the bank hiked rates against US President Trump’s wishes. It’s characteristic that Fed Chair Warsh stated that 'Inflation is too high and has been for too long’, signalling his hawkish intentions.

How Japan became the World's Banker and why that era may be ending

Japan's ultra-low interest rates helped finance trillions of dollars in global investments for more than a decade, making the Japanese Yen one of the world’s cheapest sources of funding. With the Bank of Japan expected to tighten policy again this week, that advantage may be entering a new phase. While most major economies raised interest rates, Japan remained the world's outlier.
