# Dollar Erosion: Understanding the Loss of Reserve Currency Status | Hoover Institution Source: https://www.youtube.com/watch?v=zu69mJcuWZ8 Recap page: https://rapidrecap.app/video/zu69mJcuWZ8 Generated: 2026-01-23T23:03:20.573+00:00 --- ## Quick Overview Arvin Krishna Murthy analyzes shifts in asset correlations following the 2020 tariff shock, interpreting them as evidence of a change in the perception of the dollar as the world's reserve asset, which implies a future depreciation of the dollar and a loss of wealth for the US if reserve asset demand completely disappears. **Key Points:** - The behavior of the dollar and Treasuries around the March to May 2020 tariff shock showed a major change in correlations, specifically the opposite of the typical pattern where the VIX spikes and the dollar appreciates during stress. - Historically, the spread measuring world demand for dollar safe assets (CIP wedge) averaged 22 basis points, but it turned negative during the tariff period, suggesting a flight away from Treasuries. - The speaker calculates that if reserve asset demand for dollar safe assets disappears completely, the US real exchange rate will depreciate, and equilibrium US interest rates will rise. - The calculation for the loss of the liquidity service export implies that the US dollar must depreciate to re-equilibrate the trade balance after losing the buffer provided by foreign holdings of low-yielding dollar assets. - In 2016, the total quantity of US safe assets was about 150% of GDP, with foreign investors holding 30% of that amount, equating to about 45% of US GDP in dollar safe assets. - The estimated convenience yield/liquidity service cost the US was projected to be 2% of GDP flow, based on extrapolating the relationship between the CIP wedge movements and dollar exchange rate capitalization of UIP deviation (a 10-to-1 ratio). - The speaker notes that the decline in the dollar safe asset premium began around 2022, suggesting the March/April 2020 event marked a change in a correlation already underway in asset pricing land. **Context:** The presentation by Arvin Krishna Murthy, co-authored with Zenyang Jen and Robert Richmond, focuses on analyzing financial market data, particularly around the 2020 tariff shock, to understand shifts in the perception of the US dollar's status as the world's primary reserve asset. The analysis uses asset price movements, such as the VIX, exchange rates, and specialized yield spreads like the CIP wedge, to infer forward-looking changes in investor sentiment regarding the safety and desirability of dollar-denominated assets like Treasuries. ## Detailed Analysis Arvin Krishna Murthy argues that recent asset price behavior indicates a shift in the perception of dollar safe assets as the world's reserve asset, though not a complete switch to another currency. He highlights data from the March-May 2020 period following the tariff shock, where the expected flight-to-safety correlation (VIX up, dollar up) reversed, evidenced by the dollar depreciating while yield spreads widened against foreign bonds. A key metric, the spread comparing US Treasury yields to packaged foreign government bonds (CIP wedge), which historically averaged a positive 22 basis points premium for Treasuries, turned negative, indicating a flight away from Treasuries, a trend that started falling since 2022. To quantify the implications, Murthy presents a calibrated model comparing two steady states: one where the US exports liquidity services (the world holds low-yielding dollar assets) and one where this demand disappears. Quantifying the liquidity service based on 2016 data (foreign holdings of $45% of GDP in safe assets), and assuming a 2% flow cost (derived from the CIP wedge's relationship to UIP deviations), shutting off this service requires the dollar to depreciate significantly to rebalance the trade account. Furthermore, if foreign investors dump their holdings, US interest rates must rise based on the slope of the domestic bond demand curve, leading to a measured wealth loss for the US. ### Data Analysis of Dollar Stress Behavior - The typical historical pattern of VIX spiking alongside dollar appreciation during financial panic was broken during the March to May 2020 period after the tariff war, where correlations moved in the opposite direction - The yield differential between 10-year European bonds and Treasuries widened by 50 basis points, which should imply a 5% dollar appreciation, but instead, the dollar depreciated by 6.5%. ### Measuring World Demand for Dollar Safe Assets (CIP Wedge) - The spread comparing US T-bills (FX swapped to dollars) against foreign government bonds shows a historical average premium of 22 basis points for Treasuries, consistent with flight-to-treasury flows during stress - Around April 2020, this spread went negative, suggesting a flight away from Treasuries, and the decline began notably in 2022. ### Implications of Losing Reserve Status - The model exercise compares steady states, showing that if reserve asset demand for dollars ceases, the US real exchange rate depreciates due to the loss of the liquidity service export - US equilibrium interest rates must rise based on the size of foreign holdings and the slope of the domestic bond demand curve. ### Quantifying Liquidity Services Export - Safe assets held by foreigners in 2016 totaled about 45% of US GDP, earning low yields, which represents the liquidity service provided by the US - The estimated flow cost (convenience yield) is put at 2% annually, derived by scaling the average CIP wedge movement (20 basis points) by a factor of 10 derived from exchange rate co-movements. ### Discussion on Underlying Factors - Participants discussed whether supply constraints (increased US debt) or demand shifts (sanctions, monetary policy differences) drive the change - The speaker emphasizes that the financial data suggest a general deterioration of the dollar safe asset premium against various currencies, not necessarily a specific rotation toward the Euro or Yen.
