Wall Street Journal Prime Rate

The consensus interest rate charged by ten of America’s largest banks to their most creditworthy customers, typically for loans with short-term maturities. The Wall Street Journal Prime Rate (or WSJP) is determined through a market survey and updated in WSJ when seven or more of the participating banks adjust their prime rates. It’s an essential benchmark in finance, serving as a base rate for various lending products including mortgages, auto loans, and variable credit lines.

The WSJP is approximately 300 basis points (3%) above the federal funds rate, reflecting the Federal Reserve’s monetary policy influences. It is often utilized by commercial real estate lenders as an index upon which loans are price, e.g., WSJP + 1.5%.

Putting “Wall Street Journal Prime Rate (WSJP)” in Context

In Eastwood, a burgeoning commercial hub, the Eastwood Commerce Plaza is a (hypothetical) new office project by Blue Horizon Developers, consisting of 150,000 square feet of Class A office space. This complex serves as a cornerstone for the economic growth of the area, attracting tech companies, legal offices, and a regional bank.

  • Base Rate: The interest rate for the loan is derived from WSJP as the base rate plus a 1.5% spread. With the WSJP at 8.50%, the effective rate is 10.00%.
  • Interest Calculations:
    • Annual Interest: Assuming annual compounding, the annual interest is $5 million (10.00% of $50 million).
    • Monthly Interest: This equates to monthly interest owed of about $416,667.
  • Interest Reserve: Since there is no operating income during the construction phase, an interest reserve is setup to cover the interest payments until the project is stabilized.
  • Loan Transition: Upon stabilization of Eastwood Commerce Plaza, Blue Horizons plans to sell the building to a core office investor. That new owner will likely place long-term, low leverage, fixed rate debt on the property. That fixed rate debt would likely be priced over U.S. Treasury securities (e.g. 4.50% + 250bps = 7.00% fixed rate).

This mini-case of the Eastwood Commerce Plaza illustrates one role of the Wall Street Journal Prime Rate plays in commercial real estate. By understanding these financial mechanisms, Blue Horizon Developers is better able to plan for a successful development and profitable exit.
