The yen stands to gain from a widening rate differential: Warsh is likely not to hike, even with hike odds at 85%, and has even less incentive to now, while the odds of a Bank of Japan hike spiked for Friday. If both happen, it sets up a rate-differential play into September's triple-witching options expiry. x.com  x.com 

The yen is strengthening sharply toward ¥153-154 as the Bank of Japan hikes rates and intervenes, starting to unwind the global carry trade funded by cheap yen. That is not a normal FX move but a systemic margin call on every leveraged position funded in yen, with the BOJ now playing its own game rather than following the Fed. x.com 

The US needs a weaker yen, so Treasury Secretary Bessent's visible note to "Buy Japanese Yen (JPY) $5-10 bil," chickenfeed in any case, looks like a psyop and misdirect, calling for the opposite positioning; the buying was a chunk of carry trade to close. Per @TreasuryBonds1, Japan reportedly spent about $53 billion buying yen in a single day, its largest intervention ever, and Bessent called the yen very undervalued. x.com  x.com 

The yen could see a violent short squeeze, as Treasury Secretary Scott Bessent claims asymmetric insight into Japan's next policy move and openly dared traders to short it, saying "I am the house now." If Japan tightens or intervenes again, unwinding the huge leveraged yen carry trade could force liquidations across stocks and crypto. @QmoCrypto notes Japan has sold about $71 billion of Treasuries while defending the yen. x.com 

Japan's intervention may mark a turn higher for the yen, but a surge like past appreciation periods is unlikely because there is no yen carry trade to unwind these days. Japan's near 5% of GDP current account surplus is also less structural than it looks: trade is near neutral, and the surplus comes from large investment income that is usually reinvested abroad automatically. x.com  x.com 

The US dollar's strength against the yen is a trend, as the Bank of Japan neither wants nor dares to reveal its hand. It is avoiding a clear 160 line and instead trying hit-and-run moves against yen shorts, and it is unclear whether it will actually strike. There is little basis for a sustained yen rally; even if it intervenes, its realistic approach is to fight while retreating, unless Fed policy clearly pivots, and Fed chair Warsh does not seem to want to give markets a clear signal. x.com  … Show more

The yen looks set to keep strengthening against the dollar, because Treasury Secretary Scott Bessent appears determined to push USD/JPY lower. Bessent said in an interview that as "the house" he knows exactly what Japan, the Bank of Japan and its policymakers will do when the US intervenes in the yen, and dared markets to bet against him. As a former fund manager who helped successfully attack the pound and the Thai baht, he holds a real information advantage. x.com 

The yen looks set to strengthen sharply, with USD/JPY heading to 130. The call comes as hedge funds turned the most negative on the yen since 2007, per CFTC data cited by @financialjuice. x.com 

Japan's yen interventions only buy time, so the yen is likely to keep weakening until the Bank of Japan actually moves. Reserves only help while rates stay pinned, and each round costs reserves Japan can't replace while buying less time, making intervention a speed bump for the carry trade. Japan did not save USD/JPY 160 but rented time at it; once 162 prints, the intervention narrative dies. x.com  x.com  x.com  x.com 

Going long the Japanese yen is the best trade on earth right now, because US Treasury Secretary Scott Bessent will step in to save it, with swap lines and similar measures. The yen's slide has become severe enough that Japan needs to raise rates. x.com  x.com
