He began his journalistic career at the
Baltimore Sun in 1972 and joined the staff of
Barron's in 1975. He founded ''Grant's'' in 1983. However, the publication's signature
skepticism served it, and its readers, better in the 2000s after the collapse of the
dot com bubble and the 2007-2008 crisis originating in US mortgage-backed securities. Subscription rates increased sharply for ''Grant's Interest Rate Observer'', and Grant declined several offers to buy the publication, preferring to remain a small and independent publication. Grant received the 2015
Gerald Loeb Lifetime Achievement Award for excellence in business journalism. Grant has hosted a podcast since January 2017, titled ''Grant's Current Yield''. In October 2017, ''Grant's Interest Rate Observer'' published an article by Grant and Evan Lorenz sharply critical of
Bridgewater Associates, the hedge fund created by
Ray Dalio. The article claimed Bridgewater engaged in questionable practices such as potential conflicts of interests in lending money to auditing firm
KPMG and having 91 former Bridgewater employees working at
Bank of New York Mellon, the custodial bank for Bridgewater. The article became "the talk of Wall Street", and Bridgewater denied any impropriety. A week after publication, Grant issued an apology in print and live on CNBC, retracting parts of the story and stating: “Bridgewater is a secretive and eccentric firm and I let my suspicions of that get in the way of our ordinarily comprehensive due diligence.” ==Books==
