Establishing a Ukrainian Development Bank is key to Ukraine’s post-war recovery, to foster both international trust and local ownership. This column describes how, drawing on lessons from the European national development banks and Ukraine’s recent reforms, a Ukrainian Development Bank could integrate existing financial structures, channel EU aid, support small and medium-sized enterprises, and drive economic modernisation. Balancing local ownership with robust governance and civil oversight to mitigate corruption risks will be crucial to ensure effective integration into the EU and sustainable development.

We study how central banks have used their balance sheet to absorb international monetary shocks since the late 19th century, thereby regaining some monetary policy autonomy in a context of financial openness. If the uncovered interest rate parity does not hold, an increase in the leading international interest rate may push up domestic interest rates in both fixed and floating exchange rate regimes. Central banks can partially insulate domestic short-term interest rates from this increase by expanding domestic assets. With a fixed exchange rate, this is in addition to the sterilization of foreign exchange interventions. Accounting for the response of central bank balance sheets to an exogenous international shock sheds light on some puzzling behavior of interest rates and exchange rates across international monetary regimes in history. This study is based on a new monthly dataset of central bank balance sheets, macroeconomic, and financial variables for 23 countries since 1891.

New data covering 23 countries reveal that banking crises of the Great Depression coincided with a sharp international increase in deposits at savings institutions and life insurance. Deposits fled from commercial banks to alternative forms of savings. This fueled a credit crunch since other institutions did not replace bank lending. While asset prices fell, savings held in savings institutions and life insurance companies increased as a share of GDP and in real terms. These findings provide new explanations for the fall in credit and aggregate demand in the 1930s. They illustrate the need to consider nonbank financial institutions when studying banking crises.

It is widely assumed that the renminbi (RMB) cannot acquire a meaningful place in central bank reserve portfolios without full liberalization of China’s capital account. We argue that the RMB can in fact develop into an international reserve currency in the absence of capital‐account convertibility. Trade and investment links can drive use despite limited access to Chinese financial markets. But this route to currency internationalization requires policy support. China must provide access to RMB through loans and the People’s Bank of China (PBoC) currency swaps. It must ensure the convertibility of RMB into US dollars in offshore markets. It must provide RMB services at a stable and predictable price. Currency internationalization without full capital‐account liberalization thus requires the RMB to be backed by dollar reserves, which the PBoC consequently will continue to hold and use. Hence, we do not foresee RMB internationalization as supplanting dollar dominance.
