Record advisory fees and a surge in trading revenues helped to more than double pre-tax profits at Japanese financial services group Nomura to ¥452bn (€3.2bn), their highest level in at least six years.

Profits in the financial year to March 31 soared from ¥187.6bn the previous year, while net revenues climbed by half to ¥1.1 trillion. The Japanese group said revenues and profits hit their highest level since it adopted US accounting rules in March 1999.
