We have numerically evaluated the current-current correlations for three-bandmodels of the CuO planes in high-T_c superconductors at hole doping x=1/8. Theresults show no evidence for the orbital current patterns proposed by Varma. Ifsuch patterns exist, the associated energy is estimated to be smaller than 5meV per link even if epsilon_p-epsilon_d=0. Assuming that the three-band modelsare adequate, quantum critical fluctuations of such patterns hence cannot beresponsible for phenomena occurring at significantly higher energies, such assuperconductivity or the anomalous properties of the pseudogap phase
