I imagine people have been watching the stock market and the world economy going through its trials and tribulations, and perhaps feeling a certain amount of fear.

Allow yourself to acknowledge and accept if you feel fear.  Don't fight it - the idea of "resist not evil" is applicable here.  When you allow yourself to be authentic, to acknowledge and experience your feelings - whether you feel they are good or bad - you open the door for them to pass over you and through you, you free yourself to not be a slave to them.  

Once you have allowed yourself to experience whatever your feelings are, return to who you are inwardly.  Look away from world that shows you lack and return to the inner assumption of your desired good.  Remember - the truth of your inner state is greater than the experience of the outer world, and that the outer world will conform to who you are in time.  Release fear, release doubt, release all concern and return to knowing that the truth of who you are inwardly is greater than the outer world of fact.

If nothing else, from a psychological stance the issues at play in the world today are an illusion of consciousness.  A fear that has gripped the world credit market is spinning an illusion of lack.  Transcend the racial consciousness of the world and be able to declare "be of good cheer, for I have overcome the world".  You are not a slave to outer circumstances - you are the master of your inner circumstances and, following the Law of Correspondence stated over 2,000 years ago, the outer world is subject to the inner.

Trust.
