European markets closed higher
U.S. markets were closed for the Thanksgiving holiday on Thursday. The pan-European Stoxx 600 added 0.46%, pulling back slightly from gains earlier in the day. Shares of British insurance firm Direct Line surged 41.4%, their highest level since early 2023, after it said a takeover offer from rival Aviva "substantially undervalued" the company.

Looser chip export ban by U.S.
Shares of global semiconductor suppliers, such as ASML and Tokyo Electron, jumped on Thursday on reports that the U.S. might implement export restrictions that are less strict than expected. The report stated that the U.S. is considering adding fewer of Huawei's suppliers to an export blacklist.

Tighter tungsten export control by China
China will start limiting exports of tungsten this weekend, as part of measures that control the flow of goods that can be used for both military and civilian purposes. It's a stark reversal of the past decades, when China controlled 80% of the tungsten supply chain, according to Argus. To make up for the drop in supply, companies are looking to open or resume production in tungsten mines.

Russia ruble rout
The Russian ruble weakened to 114 against the dollar on Wednesday. That's its lowest level since March 2022, shortly after the country invaded Ukraine. Russia's central bank intervened on the same day, saying it would halt foreign purchases on the domestic currency market for the rest of the year "in order to reduce the volatility of financial markets."
