A new research paper shows that German households increase their inflation expectations following increases in their energy prices. This effect is, however, absent for high-income and well-informed households as well as for firms. Higher inflation expectations can influence saving and consumption decisions and thus aggregate demand.

Banks with substantial central bank reserves are earning income from their reserve holdings in the European Central Bank’s (ECB) recent rate hiking cycle. This could make their credit supply less sensitive to the monetary policy tightening compared to other banks. This hypothesis is examined in a new study (Fricke, Greppmair, Paludkiewicz, 2023) using the new AnaCredit dataset – a credit register harmonised across the euro area.

Some households contribute only a small amount of equity when buying property financed by a loan. If they then default on the loan, lenders may incur losses. Should the problem affect a large number of lenders, this could potentially jeopardise financial stability. Minimum requirements for the own funds households need to provide can limit losses that may arise. However, this would mean that some households can no longer obtain loans in the desired amount. A Bundesbank study shows that a large proportion of the households interested in buying which would be affected by this are then willing to buy a cheaper property or to save more in order to buy at a later date. The impact on homeownership is therefore likely to be smaller in the medium than in the short term.

Internal risk models play an important role in ensuring capital adequacy at banks. Banking supervisors keep a particularly close eye on them, as banks have some degrees of freedom when it comes to model design. A new study examines the incentives for banks to implement internal risk models, analyses their impact on risk management and explains possible consequences of a new regulatory proposal regarding application of such models.

The trade dispute between the United States and China in 2018 and 2019 increased trade policy uncertainty, leading to a marked appreciation of the US dollar (USD). The obvious explanation for this is the special role played by USD investments in the global financial system as a safe haven for investors in times of high uncertainty. The USD appreciation triggered in this way in 2018 and 2019 enabled Chinese exporters to lower their prices in US dollars. As a result, the impact of the additional import tariffs imposed at the time by the United States on Chinese products was significantly reduced.
