The government of Jersey has confirmed that income support component rates will increase from January 2024.
Income support is a weekly benefit available to low-income families, made up of a range of components to reflect the size and needs of each household.
The move will directly benefit more than 5,000 low-income households.
Minister for social security, deputy Elaine Millar said she was grateful to the States Assembly for supporting the 8.6% rise.
It will see components for adults and children, household expenses, private rental costs, personal care, mobility, childcare and carers increased.
The approval comes as part of action to support islanders facing challenges with the rising cost of living, alongside additional income tax allowances.
Deputy Millar said: "Jersey's low-income retail price index tracks the typical expenditure of low-income families.
"The quarterly value of this index peaked in March 2023 at 8.6%.
"It fell in June to 6.4% and again in September to 5.8%.
"However, given the rapid rise in prices, an increase for January 2024 linked to that maximum value of 8.6% will make sure that low-income families continue to be well protected against rising prices.
"I am grateful to the States Assembly for supporting this increase and for collectively ensuring we are helping those that need it the most."
