Jane Foley, foreign exchange strategist of ABN amro, said in a report that AUD/NZD may rebound in the coming months, because the growth momentum of New Zealand's economy is far less than that of Australia. "The weakness of the New Zealand economy and the risk of further sharp interest rate cuts by the New Zealand Federal Reserve indicate that the fundamentals do not support the further performance of the New Zealand dollar against the Australian dollar." The New Zealand Federal Reserve cut interest rates by 50 basis points in November and hinted that it would cut interest rates further in 2025. The Reserve Bank of Australia kept interest rates unchanged on Tuesday. The Dutch cooperative bank predicts that the Australian dollar will rise from the current 1.0991 to 1.12 against the New Zealand dollar within three months.

The Bank for International Settlements (BIS) pointed out that huge government loans are having an impact on the global interest rate market, saying that investors have demanded higher premiums for buying sovereign bonds. In its quarterly report released on Tuesday, the agency pointed out that the swap spreads of various currencies and maturities have narrowed rapidly in recent months, which are "signs of possible oversupply". As investors are worried about huge debt and deficit expansion, the yields of government bonds in the euro zone and Japan have recently exceeded comparable swap rates. This leads to the so-called swap spread becoming negative. Because national debt is usually regarded as a safer investment than interest rate swap, it is unusual for the swap spread to enter the negative range. According to the Bank for International Settlements, the negative swap spread seems to reflect the pressure faced by investors and intermediaries because they need to absorb more government bonds in the near future. In the United States, the swap spreads for some maturities have been negative for many years.Delong Laser: There is no robot-related business at present.
