One reason that consumers are saving so little out of disposable income is that their wealth has been on the rise...recently, the main impetus has been house price appreciation. With interest rates rising now and housing prices unlikely to continuing [sic] advancing at their recent robust pace, consumers will need to curtail their spending to keep wealth growing in line with income. In other words, the saving rate might rise to more normal levels. If this happens, the falloff in spending growth by consumers could have a significant effect on overall economic activity.
