For example, lowering interest rates.

The purpose of cutting interest rates is to promote consumption and investment, when the price of non-ferrous metals will rise.

On the contrary, when inflation occurs, there will be interest rate hikes, and prices will be adjusted at this time.

There are also taxes, such as customs duties.

There is also 4 trillion investment, which will increase the demand for non-ferrous metals. If demand increases and supply does not increase, prices will rise.

There is also a policy on real estate. If the real estate policy is relaxed, the government will give more support to the real estate, such as lowering the mortgage interest rate. Real estate also needs non-ferrous metals, usually copper, and wires are made of copper.

4 trillion domestic investment is also good for non-ferrous metals.

And the situation in the United States. If the real estate in the United States is booming, then non-ferrous metals will also rise.
