The reports, published today, gave no further detail on what the announcement will contain, leaving households to speculate on whether borrowing costs will rise, fall or hold.
Interest rate decisions flow directly into family budgets, and changes typically influence the cost of variable mortgages and other loans within weeks. The outcome of tomorrow's decision is expected to be followed by analysis of what it means for the housing market and the cost of living.
Families heading into the announcement will be watching for any signal about the future direction of rates.
