The Bond Market Association (BMA) has added US corporate bond prices to its market-focused debt website, making it the only one to offer investors corporate, treasury and municipal bond prices free of charge.

Investinginbonds.com, the BMA's website, is a database that already includes the best-rated US securities, government bonds and municipal bonds. The addition of corporate debt prices from the $4 trillion (€3.6 trillion) corporate market follows the recent launch by the National Association of Securities Dealers (NASD) of a system that provides investors with corporate bond data.
