HPM is an IOU of the sovereign government – it promises to pay you $A10 for every $A10 you give them! All Government spending involves the same process – the reserve accounts that the commercial banks keep with the central bank are credited in HPM (an IOU is created). This is why the “printing money” claims are so ignorant.<br />
<br />
The reverse happens when taxes are paid – the reserves are debited in HPM and the assets are drained from the system (an IOU is destroyed). Keep this in mind.<br />
HPM enters the economy via so-called vertical transactions. Please refer back to Deficit spending 101 – Part 1; Deficit spending 101 – Part 2 and Deficit spending 101 – Part 3 for the details and supporting diagrams.<br />
<br />
So HPM enters the system through government spending and exits via taxation. When the government is running a budget deficit, net financial assets (HPM) are entering the banking system. Fiscal policy therefore directly influences the supply of HPM.
