Spillovers of higher US interest rates
Iacoviello and Navarro using a comprehensive dataset containing observations on quarterly GDP and time-varying country characteristics for 50 foreign economies, both advanced and emerging, for over 50 years find that the traditional Mundell-Fleming-Dornbusch view of foreign spillovers is: a) consistent with the response of advanced economies; but b) at odds with the response of emerging economies, where trade and exchange rate exposure to the United States do not seem to matter. For emerging economies it’s the financial channel that seems to matter the most.

Spillovers between US and German Bonds
Curcuru and al. use intraday data on futures prices on 10-year U.S. Treasury and 10-year Bund securities for the period 2005-2017 and find that spillovers from ECB announcements to U.S. Treasury yields are significant. More specifically, they estimate that half of the reaction in German domestic yields spills over to U.S. yields—a magnitude of impact that is nearly identical to that from FOMC announcements to German Bund yields. They conclude:
[…] U.S. monetary policy cannot be conducted in isolation. As the FOMC continues to remove policy accommodation, it will need to take into account the eventual removal of policy accommodation abroad and the impact this will have on U.S Treasury yields and U.S. asset prices in general.

Global financial conditions have not tightened yet
The most important reason for optimism, notwithstanding all the surrounding political noise, is that global long-term real interest rates are still extremely low. Even with all the drama surrounding Fed tightening, 30-year inflation-indexed Treasury bills are paying around 1{5e7f07e14add20b2e04f4edb85a447d3cd8121fc27b809645e9fed603c22cc5c} – far below long-term real returns, which have averaged closer to 3{5e7f07e14add20b2e04f4edb85a447d3cd8121fc27b809645e9fed603c22cc5c}. As long as the underlying global interest-rate picture is so benign, it is hard to see the big Kahuna of bond-default waves coming just yet.
