1. The $5 billion cap is only for Australian-dollar securities lending, not for all borrowings or swaps. Section 5BA(2) caps the total face value of stock and securities “denominated in Australian currency” that the Treasurer may have on loan at any time under securities lending arrangements. This cap does not apply to securities lending of foreign currency-denominated stock, nor to swap agreements under s 5B, nor to borrowing under s 3. That means the Treasurer could potentially lend larger amounts in foreign currency without statutory limit, subject only to the Governor-General’s authorisation.
2. The tax exemption in s 6B depends on an undertaking being given by the Commonwealth in the terms of issue. It is not automatic for all overseas issues. If the Commonwealth does not include an exemption clause, no statutory exemption arises. The section only gives effect to an undertaking “howsoever expressed”. The exemption applies only where the stock or security is not the property of a person in a class that includes all residents of Australia. However, the Act does not define “resident”, and the terms of the undertaking may define the excluded class. Practitioners must examine the actual terms of the issue, not just rely on the Act.
3. Delegation of powers to diplomatic mission members may create conflicts of law. Under s 5D(2), the Treasurer may delegate powers under s 5A and s 5C to a member of an Australian diplomatic mission in a foreign country. Those delegates would be operating outside Australia and potentially subject to local law. The Act does not provide any immunity from local jurisdiction for those delegates when acting under the delegation. Furthermore, s 5C waives sovereign immunity for the Commonwealth but not for individual delegates.
4. The requirement to take “sufficient collateral to cover the market value … at all times” (s 5BA(4)) imposes a continuous mark-to-market obligation on the Treasurer. This is an ongoing duty, not a one-time initial collateral call. If market values move, the Treasurer must demand additional collateral or return excess. Failure to do so could expose the Commonwealth to loss, but the Act provides no penalty. It may also give rise to a contractual claim by the counterparty if the Commonwealth fails to return collateral.
5. Section 4 creates a standing appropriation for principal and interest, but only for stock and securities “issued under this Act”. If a security is issued under another Act (e.g., Commonwealth Inscribed Stock Act) but the borrowing was authorised under this Act, it may not be covered. The definition of Stock and Security in s 2 ties back to issuance under this Act. Practitioners must ensure that the form of the borrowing instrument expressly states it is issued under the Loans Securities Act to benefit from the automatic appropriation.
6. The Act does not revoke any prior delegation or authority. Under s 3(2), the Governor-General may authorise the Treasurer to determine matters “instead of” the Governor-General determining them. But the Act does not state whether such authorisation revokes any prior written authority. If multiple overlapping authorities exist, there could be confusion as to which terms apply. The prudent course is to ensure that each borrowing has a single, clear, written authorisation.
7. Section 5C allows waiver of immunity for “any property or asset … other than any property or asset used or intended to be used for any diplomatic, consular or military purpose”. This carve-out is open-ended: there is no definition of “diplomatic, consular or military purpose”. The Commonwealth could potentially argue that any asset held by a diplomatic mission is immune, even if not strictly used for diplomatic functions. Lenders relying on foreign enforcement should be aware that the waiver may be narrower than it appears.
8. The London Registrar may make regulations under the Colonial Stock Acts (s 7(2)), but only in relation to stock issued in the UK before the commencement of that subsection. That subsection was added by amendment; stock issued after that date may not be covered. The regulation-making power is limited to the purpose of s 1 of the Colonial Stock Act 1948, which concerns matters such as registration, transfer, and payment. This is a niche provision that may not apply to most modern issuance.
