This year's edition of The Banking Litigation Law Review demonstrates that the increase in litigation involving banks shows little sign of slowing.

Although disputes arising from the 2008 financial crises are reaching their end, what might be termed 'normal' banking litigation has resumed, and is in no short supply. This crosses the full spectrum from claims by consumers against banks (relating to losses incurred either to the bank or to third parties) to claims by banks for the recovery of loans and the enforcement of guarantees. In all these cases, cross-border issues frequently arise, and banking litigation remains an important source of developments in the conflicts of laws in international commercial litigation.

The context for much of the consumer litigation is the growing – and increasingly complex – range of consumer protection regulation in the various jurisdictions under review. However, while the courts appear content to apply that legislation in order to hold banks to account, its existence – together with the more extensive rights it affords to consumers – has meant that in many parts of the world the courts are less willing to expand consumer rights beyond the context of that regulation, instead preferring to enforce the contractual rights between banks and customers strictly.

In those circumstances, we have seen a growth in the use of class actions and representative claims, often where consumers can take advantage of friendly regulation. These mechanisms are being adopted in countries where they did not previously exist, in some cases by changes in legislation, and in others by changes to court procedure. At the same time, courts in different jurisdictions are reacting very differently to this new or growing type of litigation. In some cases this is by seeking to restrict the circumstances in which such claims can be made but in others by promoting their use. It therefore remains to be seen whether the growth of class actions and representative claims against banks is really a worldwide phenomenon.

These novel forms of litigation, and other more conventional claims, are also subject to a global trend towards making both the courts and, importantly, alternative forms of dispute resolution more available to litigants. We continue to see parties encouraged to settle their claims out of court, by way of general mechanisms such as mediation or by way of specialised banking ombudsmen. Further, some jurisdictions are promoting the use of class or group settlements, which can resolve major disputes with limited court involvement.

At the same time, the impact of data protection legislation, including the General Data Protection Regulation (GDPR) in the European Union, has opened a further means by which claimants can bring claims against banks, which are inevitably major holders of personal data. The use of the GDPR both as a tool in litigation and as a source of complaint or damages in itself is, therefore, a concern for banks, both in a regulatory and in a litigation context. This concern is only likely to grow.

One bright spot for banks is a general trend in favour of upholding assertions of secrecy, confidentiality and privilege on the part of banks and their advisers against claimants. This is especially important in the context of investigations against banks. In common law jurisdictions in particular, courts now tend to treat such investigations as akin to adversarial litigation and after the concerns raised over the past year or two, now largely accept that many documents created during investigations should be protected by privilege.

Finally, the general political and economic uncertainty around the world remains a probable source of banking litigation, especially where that uncertainty negatively affects investors. Nobody is any closer to being able to say what the political or economic impact of Brexit will be either to the United Kingdom's banking sector or to that of the European Union. It would be dangerous to predict when clarity in this regard will be available.
