$ZARJPY 今天下跌1.2% — 是什么原因？

I'm still learning about currency pairs, so I'm curious what kind of factors usually drive such a significant one-day move in ZARJPY. Is it mostly news related to one of the countries, or something broader?

It looks like the Yen is strengthening across the board today, not just against the ZAR. Are you seeing similar moves in other JPY pairs?

Could be related to the broader risk-off sentiment we're seeing, but ZAR also has its own domestic challenges that often weigh on it. Are you seeing similar moves in other EM currencies today?

ZARJPY dropping like that usually makes me check the broader sentiment on emerging markets, especially with the dollar strengthening. Is there a big risk-off move happening generally, or is this more specific to ZAR?
