the "G-spread" is the spread between Govt issued bonds ( yield ) and corporate bonds ( yield )
For comparison, US AAA corp bond rate is 4.72 vs 10 yr bond at 4.42. BBB rated bonds 5.32 vs 4.42 - so spread is minimal and increases with risk.
a 5.72 spread is basically telling the investor that the risk is almost too much to take on. Which will hamper Russian corporations from obtaining $$$ thru bond offerings since no one will touch them. ( for risk of failure and lose their $$$ )
