14.2 Blockchain technology and its applications in international finance

Blockchain technology is revolutionizing international finance. It's a decentralized system that uses cryptography to create secure, tamper-resistant records of transactions. This innovation has the potential to streamline processes, reduce costs, and increase transparency across various financial operations.

From trade finance to cross-border payments, blockchain applications are transforming how we handle money globally. However, the technology faces challenges like scalability issues and regulatory hurdles. Understanding these pros and cons is crucial for grasping blockchain's impact on international financial markets.

1 of 3

• Distributed ledger technology underpins decentralized network of computers maintaining shared, immutable record of transactions
• Blocks of data form chronological chain of information linked cryptographically ensuring tamper-resistant record-keeping
• Consensus mechanisms like Proof of Work (PoW) and Proof of Stake (PoS) validate transactions and maintain network integrity
• Cryptography utilizes public and private key pairs for secure transactions and digital signatures verifying authenticity
• Smart contracts automate agreements executing predefined conditions without intermediaries (escrow services, insurance claims)

Blockchain applications in international finance

• Trade finance streamlines letter of credit processes and enhances supply chain tracking (shipping manifests, customs documentation)
• Cross-border payments facilitate faster, cheaper transactions by reducing intermediaries (SWIFT network alternatives)
• Securities settlement enables real-time clearing and settlement minimizing counterparty risk (T+0 settlement)
• Know Your Customer (KYC) and Anti-Money Laundering (AML) processes benefit from shared customer information enhancing due diligence
• Remittances lower fees for international money transfers increasing financial inclusion (migrant workers sending money home)

Blockchain Impact and Challenges

Benefits vs limitations of blockchain

• Benefits:
  • Increased transparency allows all participants to view transaction history
  • Reduced transaction costs by eliminating intermediaries (bank fees, currency exchange fees)
  • Faster settlement times enable near-instantaneous transfers (cross-border payments)
  • Enhanced security through cryptography protects against fraud and hacking
  • Improved traceability of transactions aids in supply chain management and regulatory compliance
• Limitations:
  • Scalability issues constrain transaction speed and volume (Bitcoin's 7 transactions per second)
  • Energy consumption concerns plague Proof of Work systems (Bitcoin's annual energy usage comparable to small countries)
  • Interoperability challenges hinder communication between different blockchain networks
  • Lack of standardization across platforms complicates widespread adoption
  • Privacy concerns with public blockchains expose transaction details to all participants

Regulatory implications of blockchain adoption

• Regulatory challenges arise from jurisdictional issues in cross-border transactions and defining legal status of smart contracts
• Data protection and privacy laws like GDPR conflict with blockchain's immutability principle
• Securities laws grapple with classifying blockchain-based assets and regulating token offerings
• Anti-money laundering (AML) and counter-terrorist financing (CTF) efforts adapt KYC processes for blockchain networks
• Central bank digital currencies (CBDCs) potentially impact monetary policy and require new regulatory frameworks
• International cooperation necessitates global standards and cross-border regulatory harmonization (Financial Action Task Force guidelines)
