FACTUAL BACKGROUND
8 Now although I will not repeat what is set out in the statement of agreed facts it is appropriate to highlight some CBA specific aspects. Capitalised expressions used in these reasons are as defined in the statement of agreed facts unless I have defined them separately.
9 CBA is one of Australia's largest companies. As at 30 June 2017, it had a market capitalisation of $143 billion, its net operating income exceeded $26.1 billion and its net profit after tax was $9.9 billion. At all material times, CBA has held an Australian Financial Services Licence.
10 During the relevant period, CBA was structured to include the following divisions:
(a) Group Treasury (Treasury); and
(b) Institutional Banking and Markets (Markets).
11 Treasury was responsible for managing CBA's AUD liquidity and wholesale funding requirements. Treasury was structured into smaller business units, relevantly including Liquidity Operations (LOPS) and Portfolio Risk Management (also known as Asset & Portfolio Management or Asset & Liquidity Management) (ALM).
12 During the relevant period LOPS employees and officers based in Australia relevantly included: John Pilkington - Head of LOPS; Roman Groblicki - Dealer Specialist Short End Portfolio, LOPS; and Mark Hulme - Chief Dealer, LOPS.
13 It was the policy of CBA that responsibility for providing instructions to Brokers for the conduct of transactions in the Bank Bill Market during the BBSW Rate Set Window and determining CBA's view of the mid-rate of the yield for Prime Bank Bills for submission to AFMA was centralised in a single position, the Bills Trader. During the relevant period, Mr Mark Hulme was the principal Bills Trader.
14 Markets serviced CBA's major corporate, institutional and government clients. Markets derived revenue by trading in the name of CBA in financial products with counterparties, both through financial markets and otherwise, whilst managing CBA's own risks arising from that trading and any holdings of financial products.
15 Within Markets was a desk known as the Swaps Desk or Swaps. During the relevant period, the employees of Swaps traded in and held books of financial products, including BBSW Referenced Products. Swaps traded in and held Prime Bank Bills, with a face value maximum holding limit of $1 billion. Swaps traded in the Bank Bill Market by providing instructions to the Bills Trader. During the relevant period the profitability of Swaps' trading books was an important metric by which Swaps' performance was measured at the close of each business day. The employees of Swaps were based in Australia and included, at all material times: Peter Psihoyos, who was the Head of Swaps, and Grant Barnes - Chief Dealer, Swaps.
16 Swaps entered into BBSW Referenced Products with counterparties including FRAs and interest rate swaps.
17 CBA was aware that its counterparties to BBSW Referenced Products comprised entities which did not participate in the Bank Bill Market and who were not listed public companies.
18 CBA supplied and acquired BBSW Referenced Products, including FRAs, interest rate swaps and loans which were referenced to BBSW. The entry into and the obtaining of rights and the assumption of obligations under FRAs and interest rate swaps involved the provision by Swaps of financial services covered by CBA's Australian Financial Services Licence for the purposes of paras 912A(1)(a) and (f) of the Corporations Act. In entering into FRAs and interest rate swaps, and in obtaining rights and assuming obligations under them, in the relevant period, Swaps supplied or acquired a financial service to or from the counterparty to the FRA or the swap for the purposes of s 12CB of the ASIC Act.
19 On each Sydney business day during the relevant period the books managed by Treasury and Swaps held BBSW Referenced Products and consequently the earnings of those books were affected by the rate at which the BBSW for different tenors set. The principal value of the products so affected is referred to as the Treasury BBSW Rate Set Exposure and Swaps BBSW Rate Set Exposure.
20 During the relevant period, on a given Sydney business day the books managed by Swaps contained BBSW Referenced Products in relation to which:
(a) an obligation to pay an amount of money would be quantified when the relevant BBSW was set on that day;
(b) the amount payable by Swaps to the counterparty or the amount payable by the counterparty to Swaps depended upon the rate at which the relevant BBSW was set on that day; and
(c) the profit and loss of the books managed by Swaps was affected by movement in BBSW on that day.
21 In the relevant period, Swaps employees and LOPS employees were from time to time aware of the BBSW Rate Set Exposure of each other's desk through communications with employees of that desk.
22 The statement of agreed facts specifies conduct which occurred on five dates between 31 January 2012 and 15 June 2012. On each of these occasions, CBA engaged in conduct that amounted to an attempted contravention of subs 12CB(1) of the ASIC Act. Such occasions comprised one attempt on each of 3 February 2012, 9 February 2012, 15 March 2012, 9 May 2012 and 15 June 2012, and each in respect of 3 month Prime Bank Bills (the Contravention Dates).
23 On each of the Contravention Dates, by transacting or seeking to transact via brokers by way of sale or purchase of Prime Bank Bills on the Bank Bill Market, CBA attempted to affect where BBSW set on that day, that is to say acted with an intention to seek to achieve that result.
24 The facts set out in the statement of agreed facts establish the attempt and the necessary intentional component. First, the relevant communications between CBA employees on or around each of the Contravention Dates disclose an intention to seek to change or influence where BBSW set on each Contravention Date through transacting in the Bank Bill Market. Second, CBA traded or sought to trade in the Bank Bill Market on the Contravention Dates with an intention of that nature. The communications predominantly involved employees on CBA's two desks: LOPS (within Treasury) and Swaps (within Markets). Moreover, on each of the Contravention Dates, CBA's Bills Trader acted as its "single face to the market", giving instructions to brokers in relation to CBA's trading in the Bank Bill Market.
25 I am satisfied that CBA's conduct on the Contravention Dates involved the taking of steps towards contravention of subs 12CB(1) of the ASIC Act.
26 First, the BBSW was known to be a highly significant benchmark and reference interest rate for the pricing and revaluation of Australian dollar loans, bills, derivatives, securities and other instruments, which benchmark was regarded by the market as independent, objective and transparent, and determined based upon prices for Prime Bank Bills formed by the competitive forces of supply and demand.
27 Second, CBA was a Prime Bank and a Bank Bill Market participant and accordingly enjoyed the ability and advantage to issue and trade Prime Bank Bills in the Bank Bill Market, which privileged position was unavailable to counterparties who were not Prime Banks and participants in the Bank Bill Market. It abused that privilege.
28 Third, as a member of AFMA, CBA agreed to abide by the AFMA Code of Ethics and was encouraged to use the AFMA Code of Ethics as the basis to develop and implement more detailed procedures to effect within CBA the objectives of the AFMA Code of Ethics. The AFMA Code of Ethics set out the minimum standards, principles and rules of behaviour applicable to AFMA members in the conduct of their businesses. The AFMA Code of Ethics required its members to conduct their trading activities in a fair and orderly manner, maintain the integrity of financial markets and not carry out trading that would interfere with normal supply and demand dynamics in the market for a financial product. The present case is yet another example of a disconformity between the theoretical purity of documented codes of ethics and how they are applied, if at all, in the harsh reality of the marketplace.
29 Fourth, on each of the Contravention Dates both Treasury and Swaps had a net BBSW rate set exposure that may have been advantaged if the attempt made had been successful.
30 Fifth, on each of the Contravention Dates there were counterparties to BBSW Referenced Products with CBA that were not listed public companies and were not Bank Bill Market participants who had an opposite total BBSW exposure to that of CBA, who may have been detrimentally affected if the attempt had been successful.
31 Finally, on this aspect of the matter I do not conclude and the parties have not agreed that CBA's trading of Prime Bank Bills in the Bank Bill Market on any of the Contravention Dates changed where the BBSW set on those dates. But so not to find is not to deny the attempt that was made by CBA on each of the Contravention Dates.
32 Let me deal with another matter.
33 At all material times, CBA maintained a number of policies and procedures applying to the conduct of its officers and employees. But whilst these policies were directed towards compliance, they were not adequate to address CBA's impugned conduct.
34 The attempted contraventions arose out of conduct of certain CBA staff including senior management who did not prevent or give instructions to prevent the conduct referred to in the statement of agreed facts. Nor did CBA ensure that there were in place structures, systems and procedures for the prevention of that conduct.
35 CBA did not actively monitor trading by Swaps and LOPS in Prime Bank Bills to ensure that they did not trade with a purpose of changing the rate at which BBSW set which, if successful, might have detrimentally affected certain counterparties of CBA.
36 Finally, in terms of the factual background, the statement of agreed facts has also set out a range of additional facts including the following matters.
37 First, if CBA's conduct referred to in the statement of agreed facts had been successful in changing where BBSW set, counterparties with an opposite rate set exposure to Swaps may have paid more to CBA or received less from it (as the case may be).
38 Second, from mid-2012 ASIC undertook inquiries of BBSW Panellists including CBA in relation to their involvement in the BBSW rate set process, and subsequently conducted an investigation into conduct including trading by CBA.
39 Third, since the conduct and behaviour described in the statement of agreed facts, there has been a change to the mechanism by which BBSW is calculated. On 1 January 2017 the ASX became the BBSW rate administrator, and more recently it has introduced a new mechanism.
40 On 21 May 2018 a new waterfall methodology was introduced by the ASX for the calculation and publication of the BBSW in each relevant tenor on each business day. Let me summarise some of its elements.
41 A volume weighted average price (VWAP) calculation is now the primary method used to determine the BBSW rate for each tenor for each business day. The calculation is performed over all eligible primary and secondary market transactions in Prime Bank Bills (including NCDs) transacted within the rolling maturity pool, throughout the BBSW rate set window. There are various points to note. First, the VWAP calculation is based upon actual transactions and traded yields. It is not based upon estimates of the best bids/best offers. Second, the BBSW rate set window is the broader period of 8.30 am to 10.00 am. Third, all eligible trades transacted bilaterally or through inter-dealer brokers during the BBSW rate set window must be reported and provided to the Benchmark Administrator for inclusion in the calculation. Such reporting of eligible trades must occur by 10.15 am. Fourth, the VWAP calculation is then performed over all eligible transactions observed within the BBSW rate set window for each tenor to provide the BBSW for each relevant tenor. This is then published at 10.30 am.
42 But if a BBSW rate cannot be validly calculated under the VWAP method for a particular tenor, for example, because the thresholds for each of the minimum volume ($ millions), minimum number of transactions and minimum number of counterparties have not been met, then the national best bid and offer (NBBO) calculation method is to be used to calculate the BBSW for that tenor. Further, in the event that a BBSW rate cannot be validly calculated under the NBBO method for a particular tenor, then the fall-back calculation waterfall is to be used.
43 In essence, the new calculation method is based upon actual market transactions, actual traded prices, a greater number of transactions and a longer BBSW rate set window. If the BBSW was previously susceptible to manipulation, the recent changes have substantially now minimised that risk.
