(Bloomberg) -- Illinois’s borrowing costs have fallen to the lowest level in six months as investors join Governor Pat Quinn in wagering that a law bolstering the worst- funded state pension system has “stopped the bleeding.”

The extra yield demanded on 10-year Illinois debt relative to AAA munis reached 1.43%age points on Jan. 30, the least since July 18, as the state prepares a $1 billion general- obligation bond sale this week, according to data compiled by Bloomberg. The fifth most-populous state already spared taxpayers more than $20 million on an offering in December, less than two weeks after legislators passed a pension bill that saves $145 billion over 30 years.
