Yes, when a government or central bank pumps money into the market, it is essentially buying the currency and increasing its demand, which causes its price to go up. This is a common tactic used by governments and central banks to increase the value of their currency and stimulate their economy. The increased demand for the currency also helps to strengthen its international trade value, making it more attractive to other countries.

Basically yes
