The Wall Street Journal Prime Rate is an aggregate rate that mirrors the base lending rate offered by at least 7 of the 10 largest U.S. banks. It is an average of the respective prime rates these banks charge their highest credit quality customers for loans. Compiled through a market survey and regularly published by The Wall Street Journal (WSJ), it serves as a leading indicator of the nation's best borrowing rate, reflective of the banks’ most financially stable customers.
The WSJ Prime Rate derives its name from The Wall Street Journal's practice of polling the 10 largest U.S. banks to ascertain their prime lending rate. When seven or more of them alter their prime rate, a new prime rate is published in the WSJ, making it a go-to source for a comprehensive average of prime rate reporting.
Historically, the WSJ prime rate has seen notable fluctuations. For instance, it dipped to 3.25% in Dec 2008, from 9.5% in the early 2000s, and in Dec 1980, it reached a record high of 21.50%. As of Aug 2021, it stands at 3.25%. Its variations are typically dictated by changes from the Federal Reserve's Federal Open Market Committee, which adjusts the federal funds rate every six weeks.
A bank's prime rate is the minimum rate it charges for lending to its most reliable customers, on all types of products. Additionally, it is also used as an indexed rate for variable credit products such as mortgages, home equity loans, and car loans.
Typically, variable rate loans or credit cards are driven by the prime rate as the base rate of interest, supplemented by the borrower’s credit profile. As the prime rate varies, so does the interest due, impacting the total repayment amount.
Therefore, those with variable rate debts are advised to closely monitor the WSJ prime rate as it serves as a critical signal of variable rate fluctuations. For instance, a credit card borrower with a variable annual percentage rate will experience an increase in interest rate when the bank's prime rate goes up.
