For years, Japan was the country that couldn’t raise interest rates.
Deflation wouldn’t let it.
Weak growth wouldn’t let it.
An aging population wouldn’t let it.
Now people are seriously talking about the Bank of Japan pushing rates above 2% this cycle.
That number doesn’t sound impressive if you’re looking at the Fed.
For Japan, it’s enormous.
The real story isn’t whether rates go from 1% to 2%.
It’s what that says about a country that spent nearly three decades convincing investors that ultra-low rates were permanent.
This is where I think people are looking at the wrong thing.
Everyone focuses on the next rate hike.
I’m watching what happens if Japan keeps hiking while government borrowing costs keep climbing anyway.
Japanese bond yields are already sitting at multi-decade highs, and markets are becoming increasingly nervous about the country’s debt, spending plans, and inflation outlook.
That’s a very different world from the one investors grew up with.
For years, the global financial system benefited from Japanese money searching for higher returns overseas because yields at home were almost zero.
If Japanese investors can finally earn meaningful returns without leaving home, that changes the math.
Less money flowing abroad.
More money staying in Japan.
Higher funding costs around the world.
That’s why this isn’t just a Japan story.
It’s a global liquidity story.
There’s another detail that caught my attention.
Markets are no longer debating whether Japan should normalize policy.
They’re debating how far it has to go if inflation proves more stubborn than expected.
That’s a conversation almost nobody thought we’d be having a few years ago.
The irony is hard to ignore.
Japan spent decades trying to create inflation.
Now there’s growing concern it may have created enough of it that the Bank of Japan has to keep tightening even if it hurts.
BREAKING: The Bank of Japan's total assets dropped -$146 billion in Q2 2026, to $3.97 trillion, the lowest since Q1 2020.
This also marks the largest quarterly decline since the Quantitative Tightening (QT) program began in August 2024.

The world got used to Japan being the anchor of cheap money.
If that anchor keeps moving, the effects won’t stop at Japan’s borders.
They’ll show up in bond markets, currencies, and capital flows everywhere.
