Artificial intelligence, machine learning, and the transformation of financial services
As machine learning models now forecast inflation with greater accuracy than any human committee, the question is no longer whether algorithms should set rates — but who bears responsibility when they are wrong. Edmund Voss examines the accountability gap at the heart of modern central banking.

Continue reading ▸The bank's internal NLP platform, built atop a fine-tuned variant of Llama 3, now ingests and summarises regulatory filings, earnings transcripts, and research notes at a volume that would have required three hundred analysts a decade ago. Accuracy on structured extraction tasks has reached 97.6%, surpassing the firm's own manual benchmarks.

The system has reduced transaction costs by an estimated 14 basis points per rebalance cycle, while maintaining tracking error within prescribed limits.
Continue reading ▸A new paper from Citigroup's AI research division and MIT's Computer Science and Artificial Intelligence Laboratory demonstrates that synthetic transaction datasets can train fraud detection models to within 2.1% of performance parity with real data, eliminating the need for cross-border data transfers that have stalled model development.
Continue reading ▸When Goldman Sachs launched the GS AI Assistant firmwide in June 2025, the engineering choice that drew least comment was also the most consequential: the system was designed from the outset to be indifferent to which foundation model sits beneath it.
Continue reading ▸JPMorgan’s Kinexys processes $2 billion a day. mBridge has settled over $55 billion cumulative. Ripple is signing central banks. One of these projects is a genuine threat to SWIFT’s hegemony; two are more complicated than their proponents admit.
Continue reading ▸The alignment problem is not academic. Reward hacking, distributional shift, and specification gaming are documented failure modes in deployed systems. Banks running production AI have a direct financial interest in understanding them.
