The Japanese yen falls below 162, hitting a 40-year low! Japan's intervention "red line" may move up to 163-165.

The yen exchange rate (dollar to yen) has fallen to its weakest level in forty years, prompting strategists and professional traders to start looking for the next intervention red line for the Japanese government regarding the currency. After the dollar to yen broke through the important level of 162 on Tuesday, more and more seasoned foreign exchange market strategists pointed out that 163 and higher levels will become the next key levels to watch. They believe that the Japanese Ministry of Finance may tolerate a weaker yen exchange rate than during the intervention actions in 2024. Strategists stated that due to increasingly crowded short yen positions in the market and the significant impact of this week's US non-farm payroll data, the yen may quickly reach these new thresholds. This also highlights a significant shift in the investment mentality of traders and foreign exchange strategists, as the market is concerned that the Japanese government, which previously could have pulled the yen away from its weakest level since 1986 through tougher statements, now may have a higher tolerance for a weaker yen. In a broader sense, the historic exit of the Bank of Japan from ultra-low interest rate policies is considered to be too gradual and difficult to reverse the yen's increasingly bleak downtrend. The latest exchange rate dynamics show that the yen has fallen below 162 yen to 1 US dollar and touched around 162.41 yen to 1 US dollar, the weakest level since 1986, the lowest point in forty years, indicating that the impact of the intervention measures by the Ministry of Finance from the end of April to early May has completely dissipated and failed to prevent further depreciation of the yen; the core logic behind this undoubtedly lies in the large US-Japan interest rate differential, market bets on the continued hawkish stance of the Federal Reserve, the strength of the US dollar, and the slow pace of tightening of monetary policy by the Bank of Japan. After the yen fell to 162.41 to 1 US dollar, the Japanese government still maintained a verbal intervention stance, rather than sending a stronger "final warning" signal, and the market began to focus more on whether the Japan Ministry of Finance will intervene again to weaken the yen. The market's pricing focus is shifting from "Will Japan intervene or not" to "Will Japan wait until 163, 165, or even higher levels to really take action." Although Finance Minister Koizumi and Chief Cabinet Secretary Kihara continue to reiterate that they will take appropriate action when necessary, their wording has not escalated, leading traders to judge that the Ministry of Finance's current tolerance is higher than the previous intervention range near 162. The core of the continued pressure on the yen remains fundamentals rather than pure speculation: the Bank of Japan has raised its benchmark interest rate to 1%, the highest level since 1995, but as long as the Federal Reserve remains relatively hawkish, the US dollar remains strong, and the US-Japan interest rate differential remains wide, the yen shorts will continue to test the reaction function of the Ministry of Finance. Position-wise, momentum is also strengthening: as of June 23, leveraged funds' short yen positions have increased to 115,033 contracts, close to a high since November 2017; at the same time, the market's bullishness on the US dollar has risen to the highest level in over a year. Thursday's US non-farm payroll data will be a key catalyst, and if the data reinforces expectations of a hawkish Federal Reserve, the probability of the US dollar rising to the 163-165 range against the yen will significantly increase. Japan has not run out of ammunition, but the marginal effectiveness of intervention is declining. Ministry of Finance data shows that during the period from April 28 to May 27, Japan spent approximately 11.7 trillion yen, about $735 billion, to buy yen, marking a record intervention effort, but the effect was still short-lived, as the yen subsequently returned to a trend of depreciation. This shows that unilateral foreign exchange intervention can only interrupt the rhythm and is difficult to reverse the trend; what really determines whether the yen will stop falling is whether the US-Japan interest rate differential narrows, whether the US dollar bulls cool down, whether the Bank of Japan can tighten policy more forcefully, and whether energy import pressures and fiscal risks ease. The 163-165 level seems to have become a new policy risk range, but without actual intervention, the market will continue to test the limits of the Japanese authorities; once actual Ministry of Finance intervention measures occur, it is more likely to be a phase of hurriedly pulling the yen rather than fundamentally reversing the long-term weakness. The yen falling below 162 triggers an intervention countdown: with the lowest point in forty years, will the Japanese Ministry of Finance's "red line" gradually move up? Rinto Maruyama, Senior Forex and Interest Rate Strategist at SMBC Nikko Securities, said, "The next level to watch is 163." He stated that concerns related to Ministry of Finance intervention measures have helped the yen maintain a stronger position compared to where it should have been after the most recent Federal Reserve monetary policy meeting. Maruyama stated that if the yen continues to weaken like other major currencies, the dollar to yen is now trading around 163 or 164. Ikue Saito, a forex market strategist at JPMorgan, said that if the Ministry of Finance uses the "covert ways" used in operations in 2024, the current intervention trigger point is likely to be higher. She wrote that the last intervention was limited in effect and may make the Ministry of Finance more cautious about entering the market too quickly. She added that Tuesday's price action indicated that stop losses and option barriers around the 162-162.50 area had been triggered. While Japanese Ministry of Finance officials continue to issue verbal warnings, the market is reevaluating. Finance Minister Koizumi and Chief Cabinet Secretary Kihara both reiterated on Tuesday that Japan will take appropriate action in foreign exchange markets when necessary. However, this verbal intervention has hardly prevented the yen from falling, as the yen fell to 161.41 during the Tokyo trading session. Koizumi's comments on Tuesday were not as strong as the statements before Japan launched a record intervention early in April. At that time, she even said that even if people were out or on holiday during Japan's Golden Week, they should not take their eyes off their smartphones. Before the intervention on April 30, Japan spent a record 11.73 trillion yen (approximately $724 billion) defending its currency during the period from April 28 to May 27. According to Ministry of Finance foreign exchange reserve data, this intervention likely involved the use of Japanese-held foreign securities, including US Treasury bonds. However, like the intervention actions in 2022 and 2024, this only provided temporary relief, with the yen subsequently reverting to a broader trend of depreciation. As we head into the release of Thursday's US non-farm payroll data, the risks are high, and this data may cause the yen to jump to a new level very quickly. "Historical data is not friendly to unilateral foreign exchange intervention measures. When fundamentals tilt in the opposite direction, it is extremely cruel, which is the dilemma Japan is currently facing," said Vass Karamanis, a forex strategist at Bloomberg. Masahiko Loo, Senior Fixed Income Strategist at State Street Investment Management, said, "Breaking the 162 yen level further strengthens the momentum-driven trend of yen depreciation, and the market is currently focusing on the 163-165 range, seeing it as the next key technical and psychological target, where both position risk and policy risk will become sharper." Loo added, "The threshold for immediate intervention appears to be slightly higher before the release of non-farm payroll data, as authorities may be more willing to assess whether the strengthening of the US dollar is being driven by fundamentals." The strong dollar storm returns Speculative positions are still heavily skewed towards a bearish yen and increasingly towards a bullish dollar. According to data from the US Commodity Futures Trading Commission, as of the week ending on June 23, leveraged funds increased their short yen positions to 115,033 contracts, near the highest level since November 2017. Earlier in June, the Bank of Japan raised its benchmark interest rate to 1%, the highest level since 1995, but traders expect the Federal Reserve to become relatively hawkish, maintaining a significant interest rate differential that has long suppressed the yen. As shown in the chart above, traders' bullishness on the US dollar is at its highest in over a year - as of June 23, speculators held about $34.3 billion in bullish bets on the US dollar. Investors are increasingly worried that the Japanese government hopes the Bank of Japan will remain cautious in further policy tightening, with reports indicating that the Japanese government will call for "appropriate" monetary management in its basic policy guidelines. Maruyama of SMBC Nikko stated that this actually limits the room for the Bank of Japan to raise interest rates faster and introduces additional fiscal risk. He said, "This combination leads to a sharp rise in long-term government bond yields, ultimately triggering a new wave of yen selling." Chidu Narayanan, Chief Strategist for Asia Pacific at the Bank of Wealth, said the market may continue to test where the Japanese authorities are willing to act. He said, "As the dollar rises against the yen, the market may test the Ministry of Finance's intervention willingness." While verbal warnings sometimes help stabilize exchange rates, "actual intervention will be necessary to credibly maintain intervention fears." It is worth noting that in recent weeks, there has been a significant shift in market narrative logic, with the Federal Reserve under Warsh being more hawkish than expected, combined with a super bull market dominated by AI hash power and the strong resilience of the US economy rekindling optimistic speculation about the "US exception doctrine" supporting all US dollar-denominated US assets, statistical data show that compared to other regions in the world, the US economy will continue to demonstrate strong resilience. At the same time, artificial intelligence continues to drive massive AI-related spending by enterprises and global capital flows into the stock market, with investors betting that the improvement in human labor productivity driven by AI will further boost the value of US dollar assets. This marks a significant reversal from a year ago, when themes of "hedging the US exception doctrine," global de-dollarization, and dollar depreciation trading were hot topics pressuring the US dollar. Since Warsh officially took the helm at the Federal Reserve and sent strong hawkish signals at his first Federal Open Market Committee (FOMC) monetary policy meeting, these themes have significantly cooled down. Even before Warsh took over, the US dollar was showing signs of strength, mainly because after the US and Israel attacked Iran in February, investors actively sought safe havens, making the US dollar the only appreciating asset globally for a period of time. After a rapid spike in oil prices, the US's position as the world's largest oil-producing country significantly boosted the US dollar, even though oil prices have since returned to pre-war levels. Top foreign exchange market strategists from major banks such as JPMorgan, Bank of America, and Goldman Sachs, have renewed their strong bullish confidence in the US dollar exchange rate, following Warsh's pledge to restore price stability and stimulate market rate hike bets. Meera Chandan, Global Forex Strategy Co-Head at JPMorgan, said in an interview that the Federal Reserve has "activated" the outlook for a stronger dollar. "It appears that other central banks will not catch up, and the gap between dollar-related rates and Treasury yields is unlikely to narrow significantly." The early signals from Warsh's leadership of the Federal Reserve are very clear: the central bank's monetary policy is shifting back towards "inflation control," rather than tilting towards international market stability, exchange rate coordination, or risk asset comfort. For the ASIA FINANCIAL market, this is a reality check - the primary constraint on the US central bank remains domestic inflation and financial conditions.
