The rise in the aggregate expenditure in the economy and the demand. If the Government increased the supply schedule will move to the rise which means it will increase. But on the other hand if the Government decreases the interest rates then the firms and the companies will invest more money into the business and which will lead to the less employment. It would be cheaper for the companies to buy machinery and other borrowings so this way the expenditure will increase.

On the other hand if there are majority of people are house owners and if government increase the interest rates then it will be harder for the people to pay for the mortgages. Hence the every ones house hold disposable income will decrease which means they will not be able to spend more money on the everyday expenditures.

Consumer with a variable mortgage will see a increase in monthly mortgage interest payment. However they have less income to spend.

But appreciation exchange rates will also helping decrease inflationary pressure. And import will be cheaper and there will be less demand for export. But turn down In aggregate demand the decline in competitiveness may give confidence firms to be extrawell-organized and cuts price.
