I consider that very little. For comparison, Argentina defaulted on over twice that amount in 2002 (see https://en.wikipedia.org/wiki/Argentine_debt_restructuring https://en.wikipedia.org/wiki/Argentine_debt_restructuring). It also seems fairly likely at this point that many of the remaining private holders are non-banks that purchased the debt at a considerable discount to par, but that's speculation on my part. It seems safe to say that the impact of the Greek default, at least as far as direct financial/economic matters are concerned, is going to be very limited. As far as the private sector is concerned, the damage has already been done.
