We study the screening of four-quark interaction by the ring diagram in an effective chiral quark model. This entails a medium dependent coupling which naturally reduces the chiral transition temperature in a class of models, and is capable of generating an inverse magnetic catalysis at finite temperature. These results are the first coherent description of inverse magnetic catalysis, anchored to a reliable field-theoretical basis.
