Fed Rate Decision Meets Yen Intervention as Crypto Markets Enter Perfect Storm

Crypto traders are bracing for a potential perfect storm of risks as they head into the week of September 20. The Federal Reserve's latest rate decision has left its mark on cryptocurrency markets, and investors are still repricing after the move. Meanwhile, Japanese authorities may be approaching an intervention window for the yen, which could trigger a sharp appreciation in the currency.

A stronger dollar has historically compressed BTC spot prices, while periods of dollar softening have preceded several of Bitcoin's sharpest rallies. Traders this week should track real-yield signals from the Treasury market alongside any public commentary from Fed officials, which can reset short-term positioning within hours.

Binance has also issued a security alert warning iPhone users to check whether an application called FomoPeek is installed on their devices. The app allegedly exploits iOS vulnerabilities in a way that could grant it elevated device permissions, potentially exposing sensitive data including crypto wallet information.
