ABSTRACT We analyze how regulatory constraints on household leverage—in the form of loan‐to‐income and loan‐to‐value limits—affect residential mortgage credit and house prices as well as other asset classes not directly targeted by the limits. Loan‐level data suggest that mortgage credit is reallocated from low‐ to high‐income borrowers and from urban to rural counties. This reallocation weakens the feedback between credit and house prices and slows house price growth in “hot” housing markets. Banks whose lending to households is more affected by the regulatory constraint drive this reallocation, but also substitute their risk‐taking into holdings of securities and corporate credit.
