The Globe and Mail reports in its Wednesday, Jan. 14, edition that Wall Street's relationship with the Trump administration's policies has soured. An Associated Press dispatch to The Globe reports that Mr. Trump has proposed a one-year, 10-per-cent cap on the interest rate on credit cards. His Department of Justice has launched an investigation into Federal Reserve chair Jerome Powell that many say threatens the institution's independence. Bank chief executive officers warned the White House on Tuesday that Mr. Trump's actions will do more harm than good to the U.S. economy. Bank of New York CEO Robin Vince said undermining the Fed's independence fails to achieve the administration's goals of improving affordability and living costs for Americans. Along with the attacks on the Fed, Mr. Trump is going after the credit-card industry. With "affordability" likely to be a key issue in this year's midterm elections, Mr. Trump wants to lower costs for consumers and says he wants a 10-per-cent cap on credit-card interest rates in place by Jan. 20. Whether he hopes to accomplish this by bullying the credit-card industry into just capping interest rates voluntarily, or through some sort of executive action, is unclear.
