Trade turmoil in April 2025 saw a marked change in cross-asset behaviour compared with typical patterns. Notably, the US dollar depreciated strongly while US Treasury yields rose – the opposite of what usually happens in a risk-off environment. This prompted discussions as to whether the safe-haven properties of US dollar-denominated assets might be changing. This is particularly important for euro area financial stability since euro area investors hold US dollar-denominated securities in an amount equivalent to €6 trillion, which represents a significant share of their portfolios.

I examine how households adjust the quality of their purchases in response to adverse economic shocks. Using household scanner data from Germany, I document heterogeneous responses across income levels. Higher-income households tend to reduce the quality of the goods they purchase, whereas lower-income households, who typically consume lower-quality goods, show a limited propensity to trade down, likely due to a limited ability to do so. To assess the equilibrium effects of an aggregate shift in demand toward lower-quality varieties, I implement a shift-share research design.

Exploiting three decades of detailed regional data for Germany, we find that when the Green Party is successful at the polls, local hazardous emissions decline. The level of political representation matters, too. Green politicians’ gaining influence at county level is followed largely by a decline in air pollutants that have an immediate adverse health effect. In contrast, when the Green party joins the state government, only greenhouse gas emissions that affect the welfare of future generations via climate change decline.

Euro area insurers manage several trillion euro in assets and take a long‑term investment perspective. To counteract the long period of low interest rates, they have shifted towards holding more alternative and less liquid assets. As a result, their balance sheets have become less liquid and more sensitive to market conditions overall. Meanwhile, their holdings of sovereign bonds show a significant home bias, which may have even increased with quantitative easing.
