What can you tell me about macroeconomic policy redressal for financial stability?

After the financial crisis experienced in 2008, policy frameworks meant to diminish the lack of stability in the financial market and reduce the economic recessions got redressed as an attempt to identify the macroeconomics policies' roles in the supplementation of efficiency of regulations when it comes to financial stability. Thus, three macroeconomic policies need to be addressed: government spending, interest rates in central banks, and liquidity provision.

From my perspective, government spending is a substandard policy for alleviating financial instability in the market, as it carries with it some destabilizing effects, like crowding out. Secondly, liquidity is ineffective, whereas interest rates are among the most viable policies in ensuring financial stability. Therefore, an appropriate policy should include prudent government spending, limited liquidity provision, and following financial disequilibria, reducing interest rates to promote financial stability.
