Resolves to YES
Next month's markets as well as markets on the UK's monthly GDP and interest rate decisions are here:
The UK's CPI inflation rate on 18th October is likely to be below 7% based on recent trends and forecasts. Data from August 2023 showed a decline in inflation to 5.9% and 6.7% in different metrics, with expectations of a further dip to 6.6% in October. Annual forecasts for 2023 also predict a rate of 6.1%. These predictions and the recent downward trend in inflation suggest a continuation of this pattern into October, although unforeseen events such as the Israel-Hamas conflict could potentially alter these projections for the year but given the timeframe its highly unlikely that it will affect the October rates.
