USD/JPY Shaken by Yen Intervention as Carry Trade Pressure Persists

The current movement on USD/JPY is showcasing a cautious consolidation this Friday, following one of the most significant foreign exchange intervention events since July 2024. The pair is currently trading at 156.67, remaining largely unchanged for the session after reaching a daily low of 155.48 earlier during the European trading hours. The driving force behind the sharp two-session decline is now established: Data from the Bank of Japan released on Friday indicated that Japanese authorities utilized $35 billion USD over two intervention sessions to support the yen. This amount is slightly below the $36.8 billion used in the July 2024 intervention, which resulted in a decline of over 2,000 pips in USD/JPY. The intervention was initiated when USD/JPY surpassed the 160.00 psychological threshold, which had served as the FX market’s most scrutinized warning signal for nearly two years. The 400-pip decline on Thursday, succeeded by a further drop to 155.48 on Friday, has recalibrated the entire dollar-bloc trade and significantly impacted other USD pairs, with EUR/USD reaching weekly peaks above 1.1754 and GBP/USD surpassing 1.3650 to achieve ten-week highs. The pair currently stands approximately 4 big figures beneath the intervention high, confined within the 50% midpoint of the February rally around 156.50 and the 100-day moving average at 157.26. The upcoming 21 trading days will be crucial in deciding if this situation develops into a structural top-formation or if the carry-trade dynamics reestablish themselves, drawing USD/JPY back toward the 160 threshold.

Analyzing the actions taken by Tokyo, the sequence of intervention commenced with a “rate check” — a traditional pre-intervention alert where the Ministry of Finance reaches out to FX dealers for live quotes, indicating to the market that officials are monitoring the situation closely without immediately utilizing reserves. The rate check prompted a significant decline in USD/JPY as traders adjusted their short-yen positions in light of the uncertainty surrounding potential direct intervention. Subsequently, it ensued. During Thursday and Friday, the Bank of Japan executed $35 billion in yen-buying operations, causing the pair to move through levels of 160.00, then 158.00, followed by 157.00, ultimately reaching a low of 155.48 on Friday. The historical context is of significant importance. In April 2024, when Tokyo intervened during the initial test at 160.00, USD/JPY experienced a significant decline, reaching 151.95 — an 800-pip movement. The intervention in July 2024, coinciding with the release of U.S. CPI data, reached a peak of 161.95 before driving the pair down by over 2,000 pips, aided by weaker U.S. inflation figures and increasing expectations for Fed rate cuts. The ongoing episode has thus far resulted in an approximate 450-pip decline — significantly less severe than either of the 2024 episodes, indicating that the intervention has been perceived as relatively weak to this point. In the absence of supportive U.S. inflation figures or a significant shift from the Federal Reserve, the influence of carry trades continues to hold firm, potentially leading to a quicker retreat than bearish investors might anticipate.

The fundamental reason USD/JPY exhibits distinct behavior compared to other USD pairs is rooted in the embedded carry trade — and the calculations are impressive. Despite the 450-pip unwind observed this week, USD/JPY continues to trade approximately 50% higher than its levels from early 2021. Such significant movements are not the result of chance. The construction activity is driven by ongoing demand in the face of constrained supply, supported by the interest rate disparity between the U.S. and Japan. The current Fed funds rate is more than 500 basis points higher than the BOJ policy rate. Entities and organizations have the opportunity to secure funding from Japanese banks at nearly zero interest rates, allowing them to subsequently invest that low-cost capital into higher-yielding U.S. assets, thereby benefiting from the differential. The currency-risk hedge associated with this trade entails selling yen and purchasing dollars in the FX market, thereby exerting additional upward pressure on the spot rate. When the trade unwinds, it does so with considerable intensity. The July 2024 episode highlighted the potential for collateral damage: the BoJ’s intervention coincided with a significant sell-off in U.S. tech stocks as carry-trade hedges unwound and risk capital sought safety. The asymmetric risk looms over equity markets each time Tokyo activates the kill switch.

The Federal Reserve’s policy stance is the key factor that influences the effectiveness of USD/JPY intervention. During Wednesday’s FOMC meeting — which may be Powell’s last as Chair — rates were held steady, yet an extraordinary four-way dissent emerged, altering the narrative surrounding the dollar. Beth Hammack of the Cleveland Fed pointed out that increasing oil prices are contributing to widespread inflationary pressure and remarked that incorporating an easing bias into the policy statement is “no longer appropriate given the outlook.” Neel Kashkari from the Minneapolis Fed cautioned that an extended closure of the Strait of Hormuz or harm to energy infrastructure might lead to a price shock, compelling the Fed to tighten its policy in order to stabilize inflation expectations. Lorie Logan of the Dallas Fed provided a rather unclear statement, indicating that the Fed’s forthcoming action could potentially be a reduction or an increase. Stephen Miran, the latest Trump appointee to the Federal Reserve, stood out as the sole dovish dissenter, casting his vote for an immediate reduction in interest rates. The mathematical implication for USD/JPY is clear: as the Fed’s dissent becomes more hawkish, the rate differential widens, leading to a stronger gravitational pull from the carry trade on the pair, irrespective of the volume of yen purchased by Tokyo.

Bank of Japan Governor Kazuo Ueda is confronted with a truly challenging policy dilemma, highlighting the fundamental reason why intervention alone cannot address the yen’s weakness. The primary mandate of the BoJ focuses on maintaining price stability and fostering economic growth, rather than providing support for the currency. Adjusting rates solely to protect the yen could jeopardize domestic recovery initiatives, especially as Japan continues to grapple with the inflationary consequences of high energy costs. Japan’s core CPI continues to exceed the BoJ’s 2% target; however, wage growth has not matched this increase. This situation suggests that a rate hike aimed at supporting the yen could inadvertently undermine real consumption. The adjustment of the yield curve control policy in December 2024 resulted in a limited and temporary effect on the trajectory of the yen. Markets are currently factoring in a possible rate hike from the BOJ in the near future; however, the central bank has indicated a careful approach regarding sudden shifts. The underlying factors contributing to the yen’s weakness go well beyond just monetary policy. Japan’s aging demographic is leading to lower domestic savings rates and constraining the natural demand for yen-denominated assets. Additionally, the nation’s reliance on energy imports results in ongoing trade deficits. Furthermore, corporate strategies have increasingly favored overseas investments over repatriating profits, resulting in structural capital outflows that counteract yen purchases related to intervention efforts.
