Abstract. We apply our quantum macrostatistical treatment of irreversible processes [18] to prove that, in nonequilibrium steady states, (a) the hydrodynamical observables execute a generalised Onsager-Machlup [12] process and (b) the spatial correlations of these observables are generically of long range. The key assumptions behind these results are a nonequilibrium version of Onsager regression hypothesis [11], together with certain hypotheses of chaoticity and local equilibrium for hydrodynamical fluctuations.
