Britain's vote last month to exit the European Union has raised the danger level for America's financial stability.
That's according to a US Treasury Department report released Monday.
The report says risks to the American economy remain in the "medium" range but have been exacerbated by Brexit.
The UK's vote to leave the European Union has sent British asset prices and economic growth forecasts tumbling.
The vote also helped persuade the US Federal Reserve to not raise interest rates during its last policy meeting.
