We uncover a new channel through which shocks are transmitted across international markets. As markets reacted to Covid-19 in March 2020, dollar appreciates sharply against other currencies. This resulted in a large increase in variation margin calls for insurance companies with high currency hedging position. We argue and show supporting evidence that insurance companies actively manage their positions in Treasuries to buffer margin shocks. Bonds with high insurer ownerships exhibit large negative price changes and reversals. This is more pronounced among more liquid bonds.
