"It's a standard uplift [in credit insurance claims] but it's been quick. It's staggering the number of claims we've received," Kirk Cheesman, managing director of insurance brokers NCI told Banking Day yesterday.Cheesman said that "over the last quarter of 2015, we saw a 28 per cent uplift in adverse alerts."What that developed into over the first quarter of this calendar year was a big jump in defaults and credit insurance claims."Then we had the Dick Smith and OneSteel [now Arrium] insolvencies. We feel given the direction of the risk score things will get a little worse in the short term."We see a continuation over the next two quarters. It's not drastic for these insurers, it's not diabolical."NCI brokers insurance for firms such as Atradius and Coface.Business owners "need to be monitoring their overdues," he said.
