FED or others should influence people's psychology to influence the price so it is not possible to influence the price directly. Evidence can be the volatility of the price when there is little time for any institution to make important decisions at Forex.

Lately everyone is talking about new finance crisis. But I think it's still early.

The price decline in the crypto market and stock market, even the decline in the level of life of people in my country in recent months can be a indication for inflation.
