The organisation's savings accounts are operated by the Bank of Ireland - which now offers depositors a 100 percent protection guarantee.
Savings accounts at the Post Office are becoming increasingly popular, with customers looking to safeguard their deposits.
The Post Office - whose accounts are managed by the Bank of Ireland - is doing particularly well because it offers a 100 percent guarantee for all savings deposited. Irish lawmakers passed a bill today on the guarantee, in order to shore up confidence in the nation's banking system following the market instability of recent days.
By contrast, the UK is only to offer a guarantee for the first £50,000 of savings, up from its previous level of £35,000. Therefore, the two percent of British savers who have over £50,000 in a single account will risk losing money if their bank collapses.
Speaking to the Daily Express, a Post Office spokeswoman said: "Since the amount that was protected was first changed, we have seen an increase."
Investment expert Stephen Ford at Brewin Dolphin added that people with exposure to the equities markets were also looking to the Post Office as a safe haven. "Yesterday we were inundated with calls from clients asking not about their share portfolios but where they should be putting their cash," he said.
"All our clients are asking if they should move their money. They are aware that basically Northern Rock and the Post Office are the only fully underwritten banks in this country. The Irish banks now look to be the safest in Europe."
