On May 30, the U.S. Supreme Court unanimously decided Cantero, reaffirming and elaborating on the Barnett Bank preemption standard, and remanding the case to the Second Circuit for further proceedings. Cantero addressed whether a New York law requiring the payment of at least 2% per annum interest on mortgage escrow deposits was preempted by federal law as to national banks. The Supreme Court held that the Second Circuit erred when it failed to apply the preemption standard articulated in Barnett Bank of Marion County, N.A. v. Nelson, which was incorporated by Congress into the Dodd-Frank Act. The Court rejected the lower court’s holding “that federal law preempts any state law that ‘purports to exercise control over a federally granted banking power,’ regardless of ‘the magnitude of its effects.’” The Court also rejected the approach argued by the petitioners, explaining it would “yank the preemption standard to the opposite extreme, and would preempt virtually no non-discriminatory state laws that apply to both state and national banks.”
