The peak amount bonded was 5.69M $RUNE on 3rd April.
A negligible amount of RUNE has been slashed compared to the amount that has been bonded over the past 4 months.

The 2 largest slashing events were from 89k from the Terra.UST on 9th May and the other was 84k from BTC.BTC pool

There seems to be a trend in the amount bonded vs price action of $RUNE.
When the RUNE price reached its ATH in the past 4 months, that was also when the most RUNE was bonded. In addition, as the price decreased over the next 2 months, the amount bonded also decreased.
