The dollar's uptrend against the yen should continue because the interest rate gap still favors the dollar; intervention can slow the move but not stop it. USD/JPY jumped back to 159.43, its August high, recovering more than half its drop after the joint US-Japan intervention two weeks ago. 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 US dollar is overvalued and weakening as Asian surplus countries stop recycling their surpluses into dollar reserves, an external drain. Without that recycling, both yields and the currency are in price discovery. Ken Rogoff concluded that Asia not recycling would mean a lower dollar against Asian surplus currencies and higher nominal rates, both now happening. Per @DrDavidKass, Ed Yardeni blames the global bond rout on the yen-carry unwind; the explanations are not mutually exclusive. x.com  … Show more

The yen stays weak because intervention cannot fix Japan's deeply negative real rates and a sluggish central bank. Japan deployed up to $95.6 billion over two days, and joint intervention with the US Treasury briefly lifted the yen about 2.8%, but about 85% of that rally has evaporated, with USD/JPY back near 159. The yen has lost 30.6% against the dollar in five years. Intervention did warn speculators off the 160-164 zone, and yen net shorts fell $8.865 billion in a week, the most since 2014. … Show more

The US dollar is supported by hawkish comments from Fed Chair Kevin Warsh, which led traders to sharply increase bets on a rate hike as soon as September. The Dollar Index trades around 99.6 after a sharp rise in the previous session. x.com 

The US dollar is unlikely to break out in the short term without a catalyst. An in-line PCE print pulled down 2-year and 10-year Treasury yields, the dollar index sits at major resistance at its May 2025 high, USD/JPY at 162 is a critical level for the Bank of Japan to defend, and currencies move slower than bonds. A reopened Strait of Hormuz would also help Europe and the euro recover, adding pressure; that favors short-term longs in gold and emerging markets. x.com  x.com 

The Japanese yen is weakening again despite the coordinated Bank of Japan and US Treasury intervention, having given back about 38% of the manufactured gain. More government intervention looks likely soon as the currency slides. x.com  x.com 

The yen keeps weakening despite repeated intervention, with dollar-yen back at 156. The US has no choice but to fund as many rescues of the yen as the BoJ wants, since otherwise Japan would be forced to sell its US Treasuries. The BoJ meets on the 18th, and it is unclear what it can even say. x.com  x.com 

The US dollar looks set for a multi-year bear cycle because a multipolar world needs fewer dollars. Reserve managers are diversifying, trade settles in more currencies and central banks accumulate gold instead. Against an equally weighted basket, the dollar's half-century sequence of lower secular highs is topping again on its 7-to-10-year cycle. Every major commodity bull of the past century ran alongside a falling dollar, which could also bring a second inflation wave. x.com 

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
