From today's Financial Times:
Bear Stearns sought rescue financing from Temasek of Singapore in the days before its sale to JPMorgan Chase but was rebuffed, underscoring the growing reluctance of sovereign wealth funds to make high-profile investments.
Could it be Temasek thought Bear Stearns was a bad investment and not necessarily concerned about being "high-profile" or not? More...
...Sovereign wealth funds from the Middle East and Asia that were recently asked to provide capital for Wachovia - another US bank with a strong domestic orientation - but refused.
The FT seems to imply that SWFs are not going to be interested in US businesses that are large and/or have a domestic focus. I think the conclusion should be poorly managed investment banks are never a good investment, regardless of whether its my money or a SWFs.
