| Abstract: | We build a balance sheet-based model to capture run risk, i.e., a reduced potential to raise capital from liquidity buffers under stress, driven by depositor scrutiny and further fueled by fire sales in response to withdrawals. The setup is inspired by the Silicon Valley Bank (SVB) meltdown in March 2023 and our model may serve as a supervisory analysis tool to monitor build-up of balance sheet vulnerabilities. Specifically, we analyze which characteristics of the balance sheet are critical in order for banking system regulators to adequately assess run risk and resilience. By bringing a time series of SVB's balance sheet data to our model, we are able to demonstrate how changes in the funding and respective asset composition made SVB prone to run risk, as they were increasingly relying on held-to-maturity, aka hidden-to-maturity, accounting standards, masking revaluation losses in securities portfolios. Finally, we formulate a tractable optimisation problem to address the designation of held-to-maturity assets and quantify banks' ability to hold these assets without resorting to remarking. By calibrating this to SVB's balance sheet data, we shed light on the bank's funding risk and implied risk tolerance in the years 2020--22 leading up to its collapse. |

| Abstract: | Financial dollarization is considered a source of macroeconomic instability in many emerging economies. Dollarization constrains the ability of central banks to stimulate output during economic downturns. In contrast to the conventional monetary transmission mechanism, a monetary policy loosening in a dollarized economy leads to a currency depreciation, adverse balance sheet effects, and a contraction in investment and output growth. In this paper we evaluate the role of foreign exchange reserves in facilitating macroeconomic stabilization in a financially dollarized economy. We first show empirically that foreign exchange intervention in response to capital outflows can largely reduce the volatility of output and the real exchange rate in dollarized economies. We then develop a small open economy model with foreign currency debt and balance sheets effects. Our quantitative model shows that an active foreign exchange intervention policy is sufficient for offsetting the output volatility associated with financial dollarization. These results can explain the prevalence of low macroeconomic volatility in some dollarized economies (Christiano et al., 2021) and they highlight the role of foreign exchange reserves in reducing the welfare costs of dollarization. |
