The Uninsured Deposit Premium (with Daniel Dias)
CESifo Working Paper, August 2025, download.
Abstract: We estimate the uninsured deposit premium – the difference between the rates paid on uninsured versus insured deposits – by linking observed average deposit rates to an estimated share of uninsured deposits. Using U.S. bank data from 1991 to 2025, we show that the average uninsured deposit premium rose by nearly 400 basis points over this period. This rise reflects both falling insured deposit rates and rising uninsured deposit rates. We find a strong correlation with the monetary policy cycle: a one-percentage-point increase in the Federal Funds Rate corresponds to a rise of roughly 32 basis points in the uninsured deposit premium. We develop a bargaining model between banks, insured depositors, and uninsured depositors that explains these dynamics.
The Dollar Channel of Monetary Policy Transmission (with Ralf Meisenzahl and Friederike Niepmann)
CESifo Working Paper, March 2025, download.
Abstract: We show that exchange rate movements in the dollar affect syndicated loan spreads. We identify the effect of dollar movements by focusing on spread adjustments during the syndication process. Using this high-frequency, within loan variation, we find that a one standard deviation increase in the dollar index increases spreads by about 5 basis points. The same increase in the dollar index leads to a reduction in loan amounts by 0.5 percent, and syndicate participants experience a reduction in underpricing by 3 basis points. The effects are considerably larger for dollar appreciations. The results suggest that the dollar is a strong indicator for the global demand for risky assets and that global shocks through the dollar affect corporate borrowing costs.

(Partly based on the previously circulated paper “Trade credit, Markups, and Relationships”, IFDP 1303, 2020)
Abstract: Exploiting transaction-level international trade data, this paper documents new facts about trade credit. Trade credit use increases with firm-to-firm relationship length, an effect that varies with countries’ rule of law, and is stronger for trade in more complex products and trade between unrelated parties. A model featuring diversion risk, learning, and a financing cost advantage of trade credit can rationalize these patterns. Initially, payment risk is a key factor limiting trade credit use. Through learning, this risk declines and firms switch to trade credit. Long-term trade relationships give rise to a financial benefit: saving financing costs through trade credit.
The Effect of the Dollar on Trade Prices (with Sai Ma and Shaojun Zhang) download.
Abstract: This paper provides evidence on the effect of the dollar exchange rate on international trade prices, employing a new instrument for the U.S. dollar based on U.S. domestic housing activity (Ma and Zhang (2019)). In line with the dominant currency paradigm (Gopinath et al. (2020)), when instrumenting the dollar, we find evidence for a perfect pass-through of the dollar exchange rate to import prices that are invoiced in dollars.
