Minneapolis Fed President Neel Kashkari said Monday he was worried the central bank might get too aggressive with interest-rate hikes and push the economy into recession. "Let's not overdo it," Kashkari said during a question-and-answer session in Escanaba, Mich. Low wage growth suggests there is still slack in the labor market, he said. "If we see wages pick up, we can always respond then," Kashkari said. The Minneapolis Fed president said he would be watching the yield curve closely. An inversion of the yield curve was the "very best predictor of recession," he said. Kashkari is one of two regional bank presidents urging caution on further rate hikes. The majority at the Fed is targeting at least two more quarter-percentage point moves this year. Kashkari is not a voting member of the Fed's interest-rate committee this year.
