From the creation of the IFSC, the country experienced strong and sustained economic growth which fuelled a dramatic rise in Irish consumer borrowing and spending, and Irish construction and investment, which became known as the Celtic Tiger period. By 2007, Ireland had the highest private sector debt in the OECD with a household debt-to-disposable income ratio of 190%. Global capital markets, who had financed Ireland's build-up of debt in the Celtic Tiger period by enabling Irish banks to borrow in excess of the domestic deposit base (to over 180% at peak), withdrew support in the global financial crisis. Their withdrawal from the over-borrowed Irish credit system would precipitate a deep Irish property correction which would then lead to the collapse of the Irish banking system.
