NZX credited its derivatives tie-up with the Singapore exchange (SGX) for strong activity on its dairy platforms over the month.
The record for overall daily futures volume traded was topped with 5685 lots traded, largely driven by a big trading day for skim milk powder futures and butter futures.
The daily volume record for skim milk powder futures was broken with 3600 lots traded, breaking the prior record by 43 per cent.
The daily volume record for Butter Futures was also broken with 2025 lots traded, up 32 per cent.
Overall, across the NZX's suite of eight dairy contracts, 37,156 lots were traded in May, an increase of 89 per cent on May last year.
