Japan's Finance Minister Katayama just dropped an interesting take on the recent US-Japan joint statement. According to his interpretation, the agreement essentially gives both countries the green light to step in whenever forex moves get too wild—specifically when they drift away from what fundamentals would actually support.

Why does this matter? Because currency volatility doesn't just affect traditional finance. When major economies start coordinating on forex intervention policies, it ripples through all markets, including crypto. A weaker or stronger yen relative to the dollar can shift capital flows, influence risk appetite, and ultimately impact where traders are parking their money.

The key takeaway: official intervention to keep currency moves "in line with fundamentals" is now on the table. Translation? Expect central banks to be more active if we see excessive forex swings.
