The economic data issued by the United States last week all pointed to signs of cooling economy. And the employment data, which had been strong previously, also weakened more than expected. Hence, market concerns about the Fed's interest rate hike in May have eased, and the US dollar index hovered at a low of 101. Due to the sharp drop in economic data and employment data, the 3-month US Treasury yield curve unexpectedly exceeded the 10-year counterpart by 153 basis points, the largest figure on record since January 1982.
