SQL Server - Update column from data in the same table

I have a table that looks something like this:

SetId ID Premium 
2012 5 Y 
2012 6 Y 
2013 5 N 
2013 6 N

I want to update the 2013 records with the premium values where the setid equals 2012.
So after the query it would look like this:

SetId ID Premium 
2012 5 Y
 2012 6 Y 
2013 5 Y 
2013 6 Y

Any help greatly appreciated
