  • raised the base rate by 50 basis points to 1.25 percent on Thursday

Background to the move from the HKMA:

  • The base rate is the interest rate forming the foundation upon which the Discount Rates for repurchase-agreement transactions through the Discount Window are computed
  • The Base Rate is currently set at 50 basis points above the prevailing US Fed Funds Target Rate or the average of the five-day moving averages of the overnight and one-month HIBORs, whichever is the higher.

  • The HKMA announces the Base Rate every day before the interbank market opens in Hong Kong
