Fitch has become the last of the big three credit rating agencies to strip Alaska of its prized triple A rating on Tuesday, as the 49th US state continues to grapple with the fallout from the collapse in global crude prices. Analysts with Fitch, which lowered its rating to double A plus with a negative outlook, cited the large budget deficits the state has run since the steep drop in the price of crude oil. Standard & Poor’s and Moody’s both downgraded Alaska one notch earlier this year to double A plus, US capital markets correspondent Eric Platt reports. Marcy Block, an analyst with Fitch, said the move reflected the “substantial operating deficits recorded by the state in recent fiscal years and the modest reform efforts taken to date to realign its stressed, petroleum-based revenue structure with expenditure demands”.
