SAN FRANCISCO (MarketWatch) — Standard & Poor’s Ratings Services on Monday lowered the ratings on U.S.-guaranteed bonds issued by the Israeli government to AA+ from AAA. The downgrade comes in the wake of the ratings agency’s move on Friday to strip the U.S. of its triple-A rating. However, Israel’s sovereign rating is unchanged at A with a stable outlook. The decision affects about $6 billion in debt.
