U.S. investment bank JPMorgan has downgraded its recommendation on Panama's bonds after U.S. President Donald Trump ramped up his threat this week to take back the Panama canal.

U.S. President Donald Trump’s insistence that he wants to have the Panama Canal back under U.S. control is feeding nationalist sentiment and worry in Panama, home to the critical trade route and a country familiar with U.

The answer is simple: there is no greater or more idealistic symbol of U.S. power in the world than the Panama Canal. As Trump seeks a way to enhance the country's power in the world, leaning on imagery regarding the Panama Canal provides just the right message.
