The way to protect yourself is to move your assets into another broker if IB stock collapses by 60%+Here it is:

UK and some banks like in Eire and Cyprus are covered by a different but similar protection, FSCS
I have no idea about the 25k.. and I thought any IB customer would be insured under sipc, but it's an insurance and never know when/if they pay.
Not that I see any risk in IB, but 2008 teaches a lesson.
All eggs in the same basket probably not the best idea.
