Understanding US bank prime loan interest rate (H.15 historical data)
This index reflects the basic borrowing cost applied by major financial institutions to the most liquid short-term credit. The scope covers interbank lending transactions among banks in the money market, excluding long-term loans or those with complex collateral. Unlike long-term bond yields that reflect distant growth expectations, this index directly measures the current tightness or looseness of monetary conditions.
Data is compiled and published regularly on a monthly basis, sometimes undergoing retroactive adjustments as additional information becomes available from market participants. When analyzing, users should observe the trajectory of the yield curve rather than focusing solely on a single monthly value. Comparisons are typically made between the current month and the previous month to quickly identify reversals in monetary policy.
