As the UK economy went into recession in 2008, the Monetary Policy Committee responded with a 400 basis point reduction in Bank Rate between October 2008 and March 2009. Although this easing lessened the impact of the recession across the whole economy, its cash-flow effect would have initially benefited some households more than others. Those holding large debt contracts with repayments closely linked to policy rates immediately received substantial boosts to their disposable income. Cheaper mortgage repayments meant more pounds in peoples’ pockets, and this supported both spending and employment in 2009. In this article I explore one element of the monetary transmission mechanism that works through cash-flow effects associated with the mortgage market, and show that it can vary across both time and space.
