Typically, the cost of equity is higher than the cost of debt since the former ranks lower on the capital structure than the latter. As such, by increasing the debt weight (like in the below from 50% to 25%), we also reduce the WACC.

The WACC will initially fall, because the benefits of having a greater amount of cheaper debt outweigh the increase in cost of equity due to increasing financial risk. The WACC will continue to fall until it reaches its minimum value, ie the optimal capital structure represented by the point X.
