Has there ever been a time when global fundamental events didn't steer the market? The market is made up of people, and these people pay attention to the events of the world. Both traders and investors pay attention, so when global events like wars happen, their actions affect the market. If they panic and sell, we see it in the price of bitcoin; if they don't, we also see it I the price.
Trader activity is driven by something. Something makes so many traders sell and something makes so many traders buy, and that something, among other things, is global fundamental events, like wars and diplomacy. It could also be rumours, big sales and many other things.
