Their analysis in the British Medical Journal looked at data from 54 countries to assess the global impact of the financial problems triggered by the collapse of US credit and housing markets in 2008.
In the year after the crisis began, the male suicide rate rose by 3.3% overall.
This was largely in the countries where there were more reported job losses.
There were nearly 5,000 'extra' suicides above the expected level for that year.
These were mainly seen in the 27 European countries and 18 countries in the Americas studied.
In Europe, suicides increased among 15-24-year-old men, while in America the rise was seen in the 45-64 age group.
Yet the suicide rate for women did not change in Europe and only increased slightly in America.
