Ranked: Central Bank Assets as a Share of GDP by Country - visualcapitalist.com

Central bank balance sheets have expanded far beyond their traditional role of holding foreign reserves and gold. As a share of GDP, central bank assets vary widely across countries, reflecting differences in monetary policy frameworks, exchange-rate regimes, and the scale of asset-purchase programs undertaken in recent decades.

The ratio matters for several reasons. A larger balance sheet relative to the economy can signal heavy reliance on unconventional tools such as quantitative easing, and it shapes how much room policymakers have to expand further. It also affects how sensitive a country's financial system may be to changes in interest rates paid on reserves, since those payments flow directly to the central bank's income statement.

For market participants, the key is context: a high ratio is not inherently a warning sign, but it can indicate where policy normalization may prove more disruptive. Watching how these ratios evolve alongside inflation, currency stability, and bond markets offers a clearer picture of the policy backdrop than any single ranking.
