Global European banks and dollar (co-)dependence: how housing markets became internationally synchronized
We show that US net capital inflows drive the international synchronization of house price growth through the topography of the global banking network. US net capital inflows improve US dollar funding conditions of non-US and specifically European global banks, allowing them to increase leverage by borrowing in US dollars and to expand foreign interbank lending to borrowing countries. This induces a synchronization of lending across borrowing countries, which translates into a synchronization of mortgage credit growth and ultimately house price growth. Importantly, this synchronization is driven by non-US global banks' common but heterogeneous exposure to US dollar funding conditions, not by the common exposure of borrowing countries to non-US global banks. Our results therefore identify a novel channel of international transmission of US dollar funding conditions: As these conditions vary over time, borrowing country pairs whose non-US global creditor banks are more dependent on US dollar funding exhibit higher house price synchronization.

Tracking foreign capital: the effect of capital inflows on bank lending in the UK
This paper examines how UK banks channel capital inflows to the individual sectors of the domestic economy and to overseas residents. Information on the source country of foreign capital deposited with UK banks allows us to construct a novel Bartik instrument for capital inflows. Our results suggest that foreign funds boost bank lending to the domestic economy. This result is due to the positive effect of capital inflows on bank lending to non-financial firms and to other domestic financial institutions. Banks do not channel capital inflows directly to households or the public sector. Much of the foreign capital is also channeled back abroad, reflecting the role of the UK as a global financial center.

Borrowers beware of common lenders: decomposing house price spillovers through global banks
What is driving international spillovers of house price shocks? I show that common global lenders facilitate these spillovers beyond direct spillovers among borrowing countries. Global lenders incur losses when banks in borrowing countries experience losses in response to negative house price shocks. The effect on house prices in other borrowing countries depends on whether global lenders mitigate the losses by deleveraging or by reallocating their portfolios towards safer borrowing countries (flight to safety). I build a theoretical model to disentangle these two spillover channels. I test the model empirically and find that the portfolio reallocation effect exceeds the deleveraging effect, implying an increase in house prices in borrowing countries other than those hit by the negative house price shock. Selected supply side macroprudential measures can shield borrowing countries from these spillovers. The findings highlight the importance for borrowing countries to monitor their exposure to common global lenders with lending portfolios susceptible to house price shocks.
