Volatile yen risks confused global markets, Japanese shipping chairman says

Japan foreign reserves drop record $80 billion after yen intervention

Japan's foreign reserves fell by 6.18% in August, the fastest pace since ministry records started in 2000.

Japan has spent a combined 27.1 trillion yen on interventions so far this year, the largest yearly amount ever.

Masahiko Loo of State Street Investment Management said the decline in foreign reserves is primarily due to Japan's dollar-selling, yen-buying FX interventions.

Yen jumps to one-month high on intervention speculation

Atsushi Mimura said authorities were neither satisfied nor reassured by recent currency moves and remain on heightened alert.

The yen reached a one-month high against the U.S. dollar.

Japanese investors are the largest overseas holders of U.S. Treasurys, holding around $1.1 trillion worth of U.S. debt as of June.

“But I do not think [the Ministry of Finance] has done this kind of small stealth intervention in recent history. So it is probably just a reaction to BOJ Governor Ueda's comment cementing the high likelihood of a BOJ rate hike in September,”

Bessent attacks Warren over yen intervention query

Treasury Secretary Scott Bessent attacked Sen. Elizabeth Warren on Friday.

Bessent wrote on X that Warren knows less about foreign exchange markets than she does about banking.

Bessent offered Warren and her staff a tutorial on "Foreign Exchange for Dummies".

“His effort to prop up a foreign currency hasn't worked. His failed intervention in Treasury markets was blasted by his mentor as burning 'two centuries' of credibility. Trump's economy is crushing families. Maybe he should focus on that.”

Japan's yen intervention turbo-charges carry trade

Francis Tan said the intervention only addressed a symptom but is not curing the disease.

Ashwin Binwani said he re-established dollar yen long positions just above 157 after exiting them upon news of the U.S.-backed intervention.

Jesper Koll said intervention has 'turbo charged' the carry trade for fundamental and long term investors.

“The market is far less one-sided than before the intervention, but the incentives to fund in yen remain attractive while U.S.-Japan rate differentials stay wide,”

U.S. and Japan confirm coordinated yen intervention

President Donald Trump said the U.S. participated in the coordinated intervention as a gesture of support for Japan.

The yen recently fell to its lowest level in roughly four decades against the dollar.

Bessent endorsed Japan's policy direction to correct the substantial undervaluation of the yen.
