Adult Diaper: the Japanese Yen barometer

Since 2023, the production of adult diapers in Japan has soared past that of baby diapers. Just five years ago, only one-third of diapers catered to adults, but guess what? Today, there's a 50-50 chance that a diaper produced in Japan is tailored for grown-ups, not for cute little babies!

Oh wait, there's more to this wild tale. The sushi currency JPY has taken a tumble of its own along the way.

While obviously BOJ YCC (yield curve control) and hence interest rate arbitrage can explain a lot of JPY weakness, the underlying reasons are aging population and struggling economy.

So there you go! Adult diapers have become the JPY barometer.
