The Insolvency Service found that 39 per 10,000 adults in the local authority were declared insolvent in 2017.
This is when someone cannot pay their debts, and has to arrange a plan with an official body to pay off creditors.
This can include being declared bankrupt.
That rate is almost double the average for England and Wales.
The figures are comprised of people who have been declared bankrupt, those who have been given debt relief orders (DROs), which are a form of relief for people on low incomes, and those with individual voluntary arrangements (IVAs), which are a voluntary way of paying back creditors.
In Scarborough there were 342 new insolvency cases in 2017.
DROs were the most common form of insolvency, with 193 recorded last year.
Across Britain personal debt has ballooned over the past few years, with low interest rates and payday loans contributing to the rise.
Consumer debt reached more than £200 billion by the start of the year, returning to levels last seen in the financial crisis.
In 2017 almost 100,000 new insolvency cases in England and Wales were reported.
In Scarborough the rate of insolvencies has increased by 9% over the past two years.
Overall in England and Wales the insolvency rate increased for the second successive year.
The data shows women are more likely to be insolvent than men.
Young people are also struggling, with the biggest percentage of new cases among 25 to 34-year-olds.
Graham O’Malley, debt expert at Citizens Advice, said: “Unmanageable debt puts people at risk of insolvency that, in the most serious cases, can result in them losing their home.
“There’s debt advice out there - from organisations such as Citizens Advice - that people do not have to pay for.
“It’s so important people with money problems make sure they get this impartial advice before they even think about going down the insolvency route.”
