Japan Raises Rates, Markets Do Opposite of What They're Supposed To

The Bank of Japan hiked rates. The yen collapsed. Bonds rallied. Stocks went up.

Every single asset moved in the exact opposite direction that a first-year economics student would predict. The yen weakened past 157 against the dollar instead of strengthening. The 10-year JGB yield dropped instead of rising. The Nikkei 225 jumped 1.5% when it should have tanked.

This is what happens when a central bank spends three decades training markets to ignore fundamentals. You condition an entire generation of traders to front-run interventions and fade every policy move, then act surprised when cause and effect become a joke.

Some analyst on CNBC probably spent four minutes explaining how this makes perfect sense if you consider forward guidance and real rate differentials and currency carry dynamics. He used the word "nuanced" at least twice. His chart had seventeen indicators on it. None of this will matter tomorrow.

The retail trader who bought yen calls because "rate hikes strengthen currency, I learned that in a YouTube video" is currently staring at his Robinhood account wondering if markets are broken. They're not broken. He's just poor now.

Japan's central bank spent decades proving that monetary policy is performance art. They bought ETFs. They pegged the yield curve. They went negative on rates while somehow avoiding full economic collapse. Now they hike and everything moves backward because markets stopped believing in the script years ago.

The Nikkei gained 1.5% because Japanese exporters love a weak yen, which they got despite the rate hike, which is exactly what shouldn't happen, which is why it did happen. If you understand that sentence, you've been trading Japanese markets too long and should seek help.

Somewhere a technical analyst is drawing trend lines through this data and calling it a bullish divergence. He's not wrong because nothing means anything anymore.
