Money getting more expensive

Could money in the US get more expensive tomorrow?As the Fed will officially announce the interest rate decision if a hike takes place then yes money will get more expensive in the USA.
At some point money must be more expensive to fight inflation and maybe act as a more sensible financial and investing decision.For example more expensive money makes the choice of investment decisions and their opportunity costs more logical and well thought and planned.As there is no free money almost never,if we see an interest rate hike tomorrow then some changes will be made from simple spending rules to more sophisticated financial actions and personal finance choices.
