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.

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 the Bank for International Settlements warns that artificial intelligence may amplify the speed, intensity, and complexity of financial contagion, prudent observers attend. The question is whether the institutions charged with managing that risk are themselves moving fast enough.
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.
