According to the ETF Finder at ETF Channel, MRO makes up 1.55% of the Energy Select Sector SPDR Fund ETF ( AMEX: XLE )which is trading lower by about 0.6% on the day Monday.
In particular, providing the IBRC with a bond that could be used to source ECB funding at the MRO rate would mean 40 years of paying low interest rates on this debt.
