Monetary policy and financial stability are connected to the real economy through Macro-Financial Feedback Loops. This New Keynesian framework analyzes how conditions in the credit sector can amplify or dampen macroeconomic performance.

The financial system acts as a procyclical amplifier of economic cycles:

[Real GDP Growth Spikes] ---> Asset Valuations Rise ---> Collateral Worth Spikes ---> Banks Expand Lending ---> Real GDP Accelerates Further

When real GDP grows, corporate earnings improve, and asset values rise. This increase pushes up the value of collateral available to secure loans, prompting commercial banks to loosen underwriting standards and expand credit. This surge in credit fuels higher aggregate demand and corporate investment, driving real GDP even faster. When a downturn hits, the loop reverses, converting a standard economic contraction into a severe, prolonged recession.
