Open Banking: What is it, and how does it help landlords?

Landlords often ask us about Open Banking and how we use it to help our customers at Hammock. We wrote this article to give anyone wondering about this a firm handle on what goes on “behind the scenes” of Hammock’s platform.

Open Banking is an easy and secure way to share your financial information with authorised providers. In this digital age, it’s easier than ever to manage our money. Budgeting apps, investment apps and platforms like Hammock are changing the way we save and invest.

Consumers have been able to share bank account data with third-party apps for some time.

The big change introduced on 13th January 2018 was to ensure that they have protection as they share it with authorised providers.

Open Banking reforms on 13th January 2018

Open Banking redefined the way banks deal with your financial information. The competition watchdog, the Competition and Markets Authority (CMA) that overlooks fair competition within the sector, called for these reforms.

The not so memorably named the second Payment Services Directive (PSD2) is a regulation brought in alongside that “sets requirements for firms that provide payment services and will affect banks and building societies, payment institutions, e-money institutions and their customers. As well as promoting innovation, PSD2 aims to improve consumer protection, make payments safer and more secure, and drive down the costs of payment services”

This means that all UK-regulated banks are obligated to allow you to share your financial data, as long as you give your permission. Your financial data is your bank, credit card or savings accounts and investments that your banks hold for you. This allows authorised providers that are not owned by your bank to securely offer you financial management services.

Why were these changes brought in?

The general consensus was that banking was somewhat monopolised by traditional big banks.

Once upon a time, if we wanted advice on how to manage, save and invest our money we’d go to our bank. Recently, independent technology not owned by banks has jumped ahead, offering more innovative solutions for managing our money.

Open Banking was designed to bring more competition and innovation to financial services, whilst keeping users protected. It was set up by the Competition and Markets Authority on behalf of the UK Government. It allows you to securely share your financial information with companies like Hammock in order to make your life easier.

Benefits of Open Banking

  • Flexibility. You can make the most of cutting edge technology that your bank doesn’t offer. Your financial information is kept secure and you enjoy unprecedented flexibility in managing your finances through authorised providers.
  • Increased options. With third-party apps, you’re able to do all kinds of things. From tracking your spending, aggregating your accounts to give you a better overview of your finances, analysing your shopping habits and making micro-investments.
  • Streamlined lending. If you need a personal or business loan, you no longer have to submit the information manually. You can allow lenders to securely access the relevant data directly from your bank, credit card issuer and accounting system.
  • Real-time monitoring. Third party apps can help you save money or spot fraud by providing higher visibility over your accounts in real time. Using AI and crowdsourced information, they can highlight unnecessary recurring charges and strange activity.
  • Time-saving. By using third party apps like Hammock to get automated updates on specific transactions, you save time browsing through statements to check everything manually.
  • Easier accounting. You can benefit from easier bookkeeping. With all your income and expenses in one place, preparing your tax return can be far easier.

Does this mean my finances aren’t private?

Your finances are still private, and you don’t have to share any of your financial data if you don’t want to. It’s totally your choice. Your bank will only share this information if you expressly give permission to a new provider. No one can randomly poke around in your accounts.

Hammock or any other third-party providers you sign up for, must ask for your consent if their service requires you to share financial information. If you give your consent a request will be submitted to your bank. Your bank will process this request and share the details. You can withdraw your permission at any time.

If you do decide to share your financial information with a trusted provider, they will be bound by strict regulations that protect your data.
