This paper discusses briefly implication of global financial turmoil caused initially by U.S. sub-prime loan crisis. It also touches on ethics-related issues concerning behavior of financial people in particular and global managers in general. It is argued that the traditional approach toward global management competency may be no longer complete as 1) global network of value chain has made performance of global managers along this chain more interdependent on one another, and 2) managers in charge of domestic-based operations may not insulate themselves from the foreign disastrous performance on which they can not be held accountable. In the case of financial turmoil mentioned before, it is quite clear that HQs of global financial Giants (like AIG) may be sapped and knocked by a misconduct of a far-away subsidiary employee, and still could not understand why all this happened. Our initial conclusion is if this Turmoil lesson can teach us anything, it is must be borne in mind that there is no easy way for cultivating global management human resources now as well as before.
