Genesis 47:13-14

"And there was no bread in all the land; for the famine was very sore, so that the land of Egypt and the land of Canaan also fainted by reason of the famine. And Joseph gathered up all the money that was found in the land of Egypt, and in the land of Canaan, for the grain which they bought: and Joseph brought the money into Pharaoh's house."

This is the first of three stages during the latter years of the famine in which Pharaoh became owner of all the land except that of the priests (Israel perhaps excluded), and the people became serfs on the land. In this stage, Pharaoh got all the money.
