The lobster is sometimes said to be immortal. It shows almost no sign of senescence: it does not weaken or lose fertility with age, and its cells keep dividing as though the years did not count (Smithsonian). But not ageing is not the same as not dying. The lobster dies. It dies not of old age but of the very mechanism of its growth. A lobster can grow only by shedding its whole shell in a moult, and each moult costs exponentially more energy as the animal gets larger. Between 10% and 15% of older lobsters die each year from a failed moult, and in time they stop moulting at all to conserve energy (Smithsonian, citing Maine’s Department of Marine Resources). The old shell then wears, bacteria get in, and scar tissue fixes the body to the shell. Trapped in the shell it will not shed, the animal rots. It dies because it stopped shedding, not because its time was up. ...

The speculative yen short that had built to a 19-year high fell for the first time in the week to 7 July. On the Commodity Futures Trading Commission’s positioning data, the leveraged-fund net short in the yen, futures and options combined, went from −137,828 contracts on 30 June to −104,231, a cover of 33,597 in a week. The last time the book ran heavier was the first half of 2007. Yet the yen barely moved. ...

As interest rates rise, firms buckle. Put July’s run of regional-bank losses beside the collapse of Zentoshin, an Osaka payment agent, and the story writes itself. It is half wrong. The Bank of Japan did raise its policy rate to 1.00% in June, the highest since 1995, but stripped of inflation the real rate is still deeply negative (Dai-ichi Life Research Institute). A rate of 1% is not, in itself, crushing borrowers. What changed is not the level of rates but the machinery that ran beneath them. ...

Few people had heard of the company that went bankrupt on 6 July. Zentoshin, a credit-card settlement agent in Osaka, was no household name. Yet it sat beneath the cash flow of restaurants and the night-time economy across Japan, working as their plumbing. Its liabilities came to about ¥125.9bn (roughly $790m), the largest corporate failure of the year and the first above ¥100bn since Drone Net in December 2025 (TDB, TSR). Its collapse pulled a scatter of regional banks down with it. ...

Markets have settled on a number. America’s tariff on most of its trading partners sits at 15%, and the figure has barely twitched in a year. That stability is the trap. The 15% has held while the legal ground beneath it was struck down, replaced, struck down again and rebuilt under a third statute. The rate is the one thing not moving. Everything underneath it is. This is the part the consensus underprices. A tariff is usually read as a price: a level that feeds margins, inflation and the terms of trade. A tariff imposed by presidential power is also a legal instrument with a shelf life, and the shelf life is where the information sits. There is a larger contest inside it, too. A great power is holding a tariff wall in place by hopping from one emergency power to the next as the courts strike each one down: a quiet test of how much the executive can tax without Congress, refought every few months. The market reads that test, imperfectly, as a number. Watch the rate and you learn little. Watch which statute is carrying it, and when that statute breaks, and you are reading a calendar of discrete events, each one able to move the carry trade, the business of borrowing where money is cheap to invest where it is dear, more than the tariff itself ever will. ...

In 2025 Japan ran a current-account surplus of ¥31.9trn, a record and the second in a row. Yet the yen has not stopped falling. Even after the Bank of Japan raised rates in June 2026, the currency trades around ¥161 to the dollar, close to its weakest since 1986. A record creditor’s currency sits at a four-decade low. Unless that contradiction can be resolved, the question every market participant is asking has no answer: where does the yen go next? ...

Japan logged 10,425 corporate failures in the year to March 2026, the second year running above ten thousand. Read the headline on its own and the story tells itself: the small-firm sector is finally cracking. The same dataset says something stranger underneath. Total liabilities came to ¥1.55trn, down for a second year from ¥2.25trn, and failures of firms with under ¥50m of liabilities made up 62.1 per cent of the count, a record in data back to fiscal 2000 (Teikoku Databank). The number of failures is climbing while the money involved shrinks. The two point opposite ways. ...

Speculative yen shorts have piled up to a record. And yet the options market is pricing the summer as if almost nothing will happen. The two do not belong in the same world. The latest CFTC data, for positions as of 2 June and released on 5 June, put the net yen short held by leveraged funds (futures and options combined) at 105,136 contracts, a further 18,887 deeper on the week. Each contract is ¥12.5m, so the notional yen sold runs to roughly ¥1.3tn. Open interest rose by 89,327 contracts to 559,092. Asset managers are short as well, by 62,814 net: the crowd is not one desk. The powder is close to full. ...

Daiichi Life Group told its investors on 13 February 2026 that group embedded value had risen 18% in thirteen months, to ¥9.65 trillion. The shares moved with it, up 22%. P/EV barely moved – 0.53x today against 0.51x a year ago, while European peers change hands at 0.8 to 1.0 times. An earlier piece on this site argued that Japan’s listed lifers were structurally cheap, and that a four-year J-curve in spread income would re-rate Daiichi Life Group (8750), renamed from Dai-ichi Life Holdings on 1 April 2026, and T&D Holdings (8795). The case rested on disclosed sensitivities and one early data point from Fukoku Mutual. Daiichi’s December disclosure has now turned the hypothesis into a measured fact for one of the two listed names. The market has accepted the EV growth at face value. It has not closed the discount. ...

Donald Trump extended the Israel-Lebanon ceasefire by three weeks on Thursday, pushing the 26 April expiry to mid-May. For speculators holding a yen short built to pay out on that discrete binary, the event has not dissolved; it has moved, into the same fortnight as Scott Bessent’s scheduled Tokyo stopover on his way to Mr Trump’s summit with Mr Xi in China. The shift matters because the dollar-yen floor at 160 is held not by any change in Japanese interest rates but by a new bilateral arrangement. Satsuki Katayama, Japan’s finance minister, threatens intervention; Mr Bessent, US treasury secretary, endorses her by declining to contradict her in public. This is the intervention-acquiescence model: US tacit consent to Japanese currency defence, in lieu of the January pressure on the Bank of Japan to raise rates. ...
