New Zealand farming lobby group Federated Farmers says the Reserve Bank's proposed bank capital changes are worrying farmers and will cause further slides in customer satisfaction. "The Reserve Bank's very conservative stand on this is causing quite a bit of resentment" said Fed Farmers spokesperson Andrew Hoggard. Farm debt is approaching NZ$63 billion and farmers are concerned about the increase in interest rates that the banks are predicting as a result of the proposed changes, as well as about a potential tightening of credit. The group is calling for the RBNZ to take a 'one in 100 years' approach to risk rather than its 'one in 200 years', and for it to commission independent economic research and modelling of the impact on the agricultural sector. Kiwi customer satisfaction fell from 71 per cent to 76 per cent over the past six months according to a Research First survey, with the biggest falls in the dairy sector.
