Why is It Essential to Implement Blockchain in Banking?

The banking sector has been a vital facilitator for an array of economic activities, such as lending, trading, transaction settlement, payment processing, etc. However, despite its rich history, the industry has found itself grappling with the challenges of adapting to the swiftly evolving digital landscape of the modern era.

Currently, the industry is advancing at a steady pace, but simultaneously, it is too slow to navigate its way forward. Despite the advent of advanced technology, many banking processes remain entrenched in paperwork, creating inefficiencies that consume valuable time and resources while posing security risks.

To address such security concerns and fortify defenses against evolving cyber threats, banks require robust solutions. Moreover, the need to track credit history and mitigate risks is increasingly pressing, necessitating innovative approaches to address bad debts and enhance regulatory compliance.

What’s more challenging? In this digitized landscape, banks face stiff competition from the FinTech industry, which swiftly keeps pace with digital transformation and embraces agile solutions.

The solution to all these challenges lies in striking a balance between tradition and transformation. This is where blockchain applications in banking come in. The permissionless and permissioned blockchain technology helps banks modernize their operations while upholding the trust and transparency that define their core mission in the financial ecosystem.

The use of permissioned and permissionless blockchain on traditional banks

If banks don’t adapt to this digital transformation and embrace cutting-edge tools like blockchain and AI, they will risk becoming obsolete.

Now that we know why traditional banking systems require change, it is time to explore blockchain applications in the banking industry.

What Are the Different Use Cases of Blockchain in Banking?

There are various use cases of blockchain in the banking sector, revolutionizing traditional processes and paving the way for enhanced efficiency, security, and transparency. Mentioned below are some prominent uses of blockchain in banking, let us look at them in detail:

Application of Blockchain for Banking

Settlement and Clearance Systems

An average bank transfer takes up to 3 days to settle a transaction. This is not just problematic for the consumers but also logistically difficult for the banks. A simple bank transfer today bypasses a complex system of intermediaries from bank to custodial service before reaching the recipient. This is where blockchain applications in banking come into the picture.

Blockchain acts as a decentralized ledger that keeps track of the transactions transparently and publicly. This means that instead of relying on custodial services, transactions can be settled in the public blockchain. This is one of the key benefits of blockchain in banking, making transactions speedy and simplified.

Cross Border Payment Transfer

Blockchain in banking and finance enables faster and cheaper cross-border transactions by eliminating intermediaries and reducing settlement times from days to minutes. Presently, trillions of dollars are wasted because of added fees and slow payments. For example, if you are in San Francisco and send money to London, both yours and the receiving bank will charge around a $25 flat fee.

We can easily eliminate these unnecessary charges using cryptocurrencies like Ether and Bitcoin, which are developed on public blockchains. The crypto payment mode is quick and easy, with no transaction fees. Moreover, since the payment happens on a decentralized network, there is no need for transaction verification, making the payment transfer faster and cheaper.

Ripple, for instance, offers a blockchain-based solution for real-time cross-border payments, allowing banks to bypass the traditional SWIFT network.

Fraud Prevention and Security

Banks have to keep track of who owns debt, stocks, or commodities in order to buy or sell them. To get this information, they connect with multiple exchanges, brokers, clearing houses, custodian banks, etc.

The involvement of these parties, combined with an outdated paper ownership system, delays the process while making it prone to inaccuracy, fraud, and data breaches. Also, the risk of technical glitches, human errors, and cyberattacks can further keep sensitive customer data at potential risk.

Financial institutions can leverage blockchain applications in banking to eliminate the layers of multiplicity and single points of failure. Since blockchain works on a single ledger system, it empowers banks to reduce the layers, minimize the room for errors, and reinforce security.

Moreover, with smart contracts, banks can swiftly detect and flag anomalies or suspicious transactions, preventing fraud and cyber theft.

Asset Tokenization

Blockchain applications in banking enable the tokenization of assets, such as real estate, stocks, and bonds, allowing fractional ownership and easier transferability. Banks can issue tokenized assets on blockchain platforms, facilitating faster settlement and enhancing liquidity in financial markets. Through a distributed ledger, it becomes easier to transfer assets through tokens that represent them “off-chain.”

Mathew McDermott, head of digital assets at Goldman Sachs, told CNBC

Loans and Credits

Banks tend to underwrite loans based on a credit reporting system because when a consumer applies for a loan, banks evaluate the risk they will have to suffer in case of non-payment. They make the loan approval decision by looking at the credit score, ownership status, and debt-to-income ratio. The information they get through credit reports is a centralized system that can be hostile to customers.

Blockchain in banking comes with an alternate lending system that provides an efficient, cost-effective, and secure mode of giving personal loans to customers. With a decentralized registry of payment history, it becomes easier for consumers to apply for loans and get approval.

Customer KYC

In several scenarios, banks can take up to three months to execute all the Know Your Customer (KYC) proceedings, including photo verification, address proof checks, and biometrics verification. In addition to the time it takes to verify the customers, it also costs banks a lot to perform KYC. Blockchain for banking helps ease the KYC process by creating a shared and immutable database of customer identities and transaction histories.

Banks can securely verify customer identities and track transaction trails in real time, reducing the risk of fraud and ensuring regulatory compliance. This enables banks to access information related to KYC anywhere and at any time.

Bank use cases for Blockchain

Digital Identity Management

Blockchain in banking provides a secure and decentralized framework for verifying and managing digital identities, reducing the risk of identity theft and fraud. Banks can use blockchain-based identity solutions to verify customer identities securely and share identity information across different financial institutions.

FinTech startups like Cambridge Blockchain and Tradle rely on blockchain for identity verification, which helps store data proofs and reuse the information for other banking-related operations.

Smart Contracts

Blockchain-based smart contracts automate and enforce contract terms without the intervention of intermediaries, reducing processing times and costs. With smart contracts, banks can utilize DeFi platforms for various applications, including loan agreements, insurance claims processing, and derivative contracts. DeFi platforms like Opyn and AAVE leverage smart contracts to enable sophisticated transactions like borrowing and lending.

Regulatory Compliance

The immutable nature of blockchain also enhances regulatory reporting and compliance by maintaining a tamper-proof record of transactions and regulatory data. Using blockchain, banks can automate the collection and reporting of regulatory information, reducing the burden of manual reporting and ensuring data integrity while maintaining unparalleled transparency of every transaction done on the blockchain.
