The quantum imperative for Guyana's financial sovereignty

The quantum imperative for Guyana’s financial sovereignty

Feb 12, 2026 Letters

Dear Editor,

The recent global call for governments and the private sector to prepare for the quantum computing era represents a critical warning that Guyana cannot afford to ignore. As we push forward with our national digital transformation, we must recognize that the encryption currently securing our banking transactions and sovereign data has a rapidly approaching expiration date.

Leaders in the global tech industry have recently emphasized that while a large-scale quantum computer may not yet be operational, malicious actors are already practicing “store now, decrypt later” tactics, harvesting our encrypted financial data today to unlock it the moment the technology matures.

This emerging reality makes the modernization of the Bank of Guyana and our commercial banking sector an issue of national security rather than just economic efficiency.

Within the context of recent discussions regarding the need for a more proactive Central Bank, we must ensure that “proactivity” includes a transition to post-quantum cryptography. For a nation like ours, currently building its digital rails and expanding financial inclusion, failing to adopt quantum-resistant standards now would be like building a new vault with a lock that is already being phased out globally.

To maintain our financial sovereignty, our policy response must be sophisticated and immediate. The Bank of Guyana should consider mandating a quantum readiness audit for all financial institutions to identify legacy systems that rely on vulnerable 2048-bit RSA encryption. Our path forward should prioritize what experts call “crypto-agility,” allowing our systems to update to the 2024 NIST-finalized standards without disrupting the daily flow of commerce.

This is particularly vital as we look to integrate more closely with our neighbors in the Global South and develop our Orange Economy, where intellectual property and digital assets will become the new currency of progress.

We are currently at a moment of unprecedented opportunity to shape a resilient future. However, that future depends on our ability to protect the integrity of our digital economy before the shift in computing power renders our current defenses obsolete.

By aligning our banking reforms with post-quantum security today, we ensure that Guyana’s wealth and the private data of our citizens remain secure in a world of rapid technological change.

Respectfully,

Dr. Walter H. Persaud
