Lately, though, currency traders have been staring at an anomaly. The one-month Hong Kong interbank offered rate, or Hibor, has collapsed since early May. The gap with the US secured overnight financing rate, or SOFR, is at an unprecedented level of more than three percentage points. Investors are now asking what caused this divergence and whether Hibor will stay lower for longer.
Interest rates in Hong Kong have been eerily low, raising the question of whether the city’s dollar peg is now in name only.
Hong Kong surrendered its monetary autonomy decades ago, thanks to a unique mechanism that restricts its currency fluctuation to a narrow band of 7.75 and 7.85 per dollar. That means the city’s borrowing costs move in lockstep with those in the US, which are dictated by the Federal Reserve’s rate policies.
