As Nomura writes, while we would like to be able to predict black swans, by definition they are unpredictable. However, its close cousin, the grey swan, can be envisaged.

These are the unlikely but impactful events that, in our opinion, lie outside the usual base case and risk scenarios of the analyst community. So we have donned our creative hats and have come up with 10 potential grey swan events for 2017. We have avoided the more widely discussed scenarios (e.g., a break-up of the euro area, a Trump impeachment or a China implosion). Instead, we have selected topics that have not been as widely discussed. Needless to say, none of them are our base case, but we think it is better to be prepared than not. Potential grey swan events for 2017 include:

Shock 1: US productivity booms

Shock 2: China floats currency

Shock 3: EU reforms, UK rejoins

Shock 4: Japan inflation surge

Shock 5: Fed muzzled

Shock 6: Russia flexes its muscles

Shock 7: Clearing houses fail

Shock 8: Japan's Abe loses power

Shock 9: EM capital controls return

Shock 10: Paper money disappears

Here is Bloomberg's summary of Nomura's 10 events that could end up roiling your 2017.
