THE dollar last week rose the most in more than a year as a US jobs report exceeded all forecasts, highlighting a growing gulf between the world's largest economy and other developed nations.

The euro sank the most since September as two European Central Bank (ECB) officials said policy makers may consider broad-based asset purchases in January. The yen weakened beyond 120 per dollar for the first time since July 2007.

The greenback added 2.4 per cent to 121.46 yen, rising for a seventh week and advancing the most since Oct 31. It touched 121.69 yen, the highest since July 2007. The dollar rose 1.4 per cent versus the euro, the most since Sept 5. The shared currency appreciated one per cent to 149.23 yen, climbing for an eighth consecutive week to extend its longest streak of gains since February 2013.
