What are the top 3 assets in the world?

I'm curious to understand the current global landscape of assets. Could you please elaborate on what are considered the top three assets in the world? I'm interested in understanding their characteristics, significance, and the reasons why they occupy such a prominent position. Are these assets primarily financial instruments, commodities, or perhaps something else? Additionally, how do these assets compare to others in terms of value, liquidity, and overall popularity? I'm eager to gain insights into this fascinating topic.
