Chinese credit rating agency Dagong has downgraded the rating outlook of New Zealand to negative, warning that increasing interest rates will curb economic growth and slow down the pace of achieving fiscal balance.
"The growing domestic market expectation for an interest rate hike will curb the economic growth, which is expected to face slowdown pressure. While... the overheating domestic real estate sector... will lead to the rise of both domestic and external interest rates, which will restrain private consumption and investment," Dagong said in a statement.
Local economists are predicting an increase in the Official Cash Rate of 125 basis points to 3.75 per cent by the end of the year - which could mean that banks lift their floating interest rates to about 7 per cent.
Dagong said the tightening of New Zealand's monetary policy will put pressure on the banking industry's assets quality and liquidity.
"In recent years, the low-cost domestic and foreign capital elevated the price of domestic real estate and generated credit bubbles. In addition, the rising cost of external financing will exacerbate the debt burden and liquidity pressure of the banking system."
