Steve explains that when governments spend more than they tax, they create deposits in private bank accounts and matching reserves for the banking sector. Bond issuance doesn’t “fund” this spending — it simply prevents the Treasury’s account at the central bank from going into overdraft, because most governments have imposed legal restrictions on doing so. Phil pushes on the role of banks, reserves and the idea of “bond vigilantes”, while Steve clarifies the difference between the primary and secondary bond markets, and why private banks are never constrained by reserves when issuing loans.
The conversation also tackles common misconceptions: that banks lend out deposits, that reserves are part of the money supply, or that bond sales create new money. Instead, Steve shows how reserves move around the system, why they can only be used for interbank settlement or buying bonds, and how government deficits are the true source of reserve creation. The result is a clear, engaging walkthrough of a system that’s often presented as mysterious — but becomes surprisingly logical once the accounting is laid bare.
