D.C. officials will tell Wall Street on Friday that the District deserves a bump in its credit rating after substantially increasing its cash reserves.

District leaders, including Mayor Vincent Gray, will spend the day meeting with officials from Standard & Poor’s, Moody’s and Fitch, all of which issue assessments on D.C. finances that help drive the interest rates the city pays on its bonds. A ratings upgrade could ultimately save the District tens of millions of dollars.
