Of course, we all know (??) that the bonding requirement was increased to a maximum of $1 million for a plan that holds employer securities. (See ERISA Section 412(a), last sentence, as amended by PPA '06.) So, yes, it certainly can go over $500,000.
But, I think your question is whether the limits of the bond set by ERISA Section 412 somehow prohibit a plan from being bonded in excess of those amounts. I am certain that the answer is "no". There is no reason that a higher bond would be prohibited--other than the argument that, if the plan is paying the bond, the price for a large bond might be excessive.
More specifically, the ERISA bonding section merely indicates the minimum amount of bonding that is required so that a violation of Section 412 does not occur. Notice that the regs say that "no such bond shall be required in excess of $500,000 . . ." (ERISA Regs. Section 2580.412-11, emphasis added), which to me means eactly what it says: EBSA cannot require more than that. It doesn't mean that more is prohibited.
I believe the $1,000,000 limit only applies if the plan holds employer securities.
