The Reserve Bank of New Zealand has given local lenders an extra six months to meet an increased target for their core funding ratio as global market turmoil puts the brakes on banks' ability to tap offshore markets for long-term debt.
Banks will have to lift the ratio of locally sourced retail deposits and long-term foreign funding to 75 per cent in 2013 as access to overseas debt markets tightens, the Reserve Bank said in its latest financial stability report.
The ratio was introduced to ensure New Zealand banks weren't relying too much of short-term loans from foreign lenders, which could put them under pressure if the financial system collapsed as it did in the 2008 global financial crisis.
"Given the current market tensions, the Reserve Bank has decided to defer by six months its planned further increase in the core funding ratio, which was to have occurred in July 2012," said deputy governor Grant Spencer. That gives "the banks more latitude in managing their funding programmes."
The decision comes as Europe's sovereign debt crisis escalates, with markets focusing on Italy's ability to repay maturing bonds after Greek policymakers united to form a coalition government in a bid to meet the austerity terms imposed by its bail-out package. Italy's woes have forced the resignation of controversial Prime Minister Silvio Berlusconi, who will step down after passing his own cost-cutting measures next week.
