Objective: To examine the response of fintech credit and traditional bank credit to monetary policy shocks using a PVAR analysis. The study utilizes a novel credit dataset from 19 countries.

Key Findings:

• Fintech credit shows lower and often non-significant sensitivity to monetary policy shocks compared to bank credit.
• Bank credit exhibits significant negative responses to monetary tightening, such as reduced asset prices and GDP.
• Fintech credit's macroeconomic impact is marginal, explaining less than 2% of real GDP variability, whereas bank credit explains approximately a quarter.

Methodology:

• Employed a Panel VAR (PVAR) model with annual data from 2005 to 2020, including variables like property prices, real GDP, and short-term interest rates.
• Used impulse response functions (IRFs) and forecast error variance decompositions (FEVDs) to analyze dynamics.
• Included robustness tests by varying Cholesky ordering, adding equity issuance, and exchange rate variables, with stable results.

Implications:

• The results indicate that fintech credit may not effectively transmit monetary policy, contrasting with bank credit.
• Fintech credit's limited contribution to GDP variability underscores its current marginal role in monetary transmission.

Conclusion:

• Fintech credit has reduced responsiveness to monetary policy shocks and minimal macroeconomic significance, unlike bank credit, which remains a key channel for policy transmission.
