Found on website of "G20 Information Centre": the "Documents and Declarations G20 Leaders Summit on Financial Markets and the World Economy November 14-15, 2008, Washington DC" and other related documents.
The "Declaration of the Summit on Financial Markets and the World Economy" is available inside.
It is a great read, particularly the "Common Principles for Reform of Financial Markets" and its more detailed "action plans" part.
Its timeline: Immediate Actions by March 31, 2009; Medium-term actions.
Its "common principles for reform":
1. Strengthening Transparency and Accountability
2. Enhancing Sound Regulation
3. Promoting Integrity in Financial Markets
4. Reinforcing International Cooperation
5. Reforming International Financial Institutions
There will be lots of new regulations and standardizations, in global scale, provided a consensus can be reached.
Some of the international bodies/"guidelines" etc. that are mentioned in the documents may worth a search or understanding to get a glimpse on the future "world financial order" will be (however, the list below is not exhaustive):
- IMF, World Bank and other multilateral development banks (MDBs)
- Financial Stability Forum (FSF)
