WELLINGTON — The Reserve Bank of New Zealand held its official cash rate at 5.50 percent, defying market pricing of a 40 percent probability of a 25 basis point cut. The hawkish hold sent the New Zealand dollar 0.8 percent lower to 0.5980 against the U.S. dollar.

The yield curve steepened sharply on the decision. Two-year New Zealand Treasury yields jumped 12 basis points to 5.25 percent, while 10-year yields rose 8 basis points to 4.88 percent. The front-end compression that rate-cut traders had positioned for reversed instantly, repositioning the curve for a prolonged hold.

The RBNZ cited persistent inflation pressures despite recent economic slowdown. This stance creates acute divergence risk as other developed market central banks signal easing. Carry traders face margin compression: the NZD's yield advantage narrows if the Federal Reserve and Bank of England cut first, potentially triggering unwind flows that pressure the currency further.
