Let's assume the the Yuan is admitted with a 10% weighting, and the weighting of each existing participant are reduced proportionally:
The shift might cause the selling of $11.7 billion in US Treasuries as reserve assets are reorganised.
That is not going to collapse the US treasury market and cause a run on the dollar. So if the Yuan is admitted to the SDR basket, I do not expect disruptions to currency and bond markets that might justify investment in defensive assets like precious metals.
