G7 central banks publish their first shared quantum report
11 MAY 2026, BASEL
G7 central banks published their first shared report on quantum computing and the financial system on 11 May 2026. The report marks coordinated attention among the group to how quantum computing affects finance, building on the work of their joint quantum working group that the Bank of Japan and others take part in.
The report informs rather than mandates. As a shared document by central banks, it shapes the participants' thinking instead of imposing requirements on commercial banks. Its influence reaches the wider sector indirectly, through how each member central bank reflects the thinking in its own supervision and operations.
A first shared report carries significance beyond its contents. It shows G7 central banks treating quantum as a collective concern worth coordinating on, not merely an issue for individual institutions. That coordination raises the chance of consistent expectations across major markets, which matters for internationally active banks that would otherwise face divergent approaches.
Why it matters. The first shared G7 central bank report signals that quantum risk has become a coordinated priority among the world's leading central banks. It binds no commercial bank directly, but it points to where consistent supervisory thinking is forming. Internationally active banks should expect the ideas developed in this forum to shape the expectations their own central banks eventually set, so early preparation stays prudent.
