Stocks declined globally on Monday as investors braced for a week packed with risk events, from central bank decisions to a G-20 gathering. Commodities were broadly weaker, Treasury yields rose and the pound jumped on hopes for a Brexit breakthrough.

U.S. stock futures slumped, with contracts on the Nasdaq 100 Index off 1.4 percent, as technology companies were roiled by weekend reports of a Facebook Inc. data breach and news that Apple appears poised to disrupt its supply chain. That sapped Asian equities, while tech shares also led a retreat for the Stoxx Europe 600 Index. The gauge’s drop is set to trigger a trading pattern known as a “death cross,” a bearish sign for many technical analysts.

Sterling rallied as the Wall Street Journal reported that the European Union agreed Monday on the broad terms of Britain’s two-year transition deal after leaving the bloc. The yen fluctuated amid a drop in support for Japanese Prime Minister Shinzo Abe’s cabinet, which has championed currency weakness.

Amid the busy week, the biggest focus for global markets will be the first U.S. interest rate decision under new Federal Reserve Chairman Jerome Powell. It comes after he hinted to investors that he’s open to lifting the policy rate four times this year, rather than the three currently reflected in dot-plot forecasts. Some Wall Street banks such as Goldman Sachs Group Inc. expect the median projection to rise to four on Wednesday, while others say there will be no change following a round of mediocre data and policy makers’ stated intentions to move gradually.

Trade tensions also remain in the spotlight as U.S. Treasury official David Malpass said he misspoke hours after claiming America was pulling out of decade-old formal economic talks with Beijing. Meanwhile, investors are assessing the implications of a new head at China’s central bank.

Elsewhere, the ruble weakened for a sixth day, the longest losing streak since October, as Russian President Vladimir Putin won a landslide victory in a tightly controlled election. Bitcoin recovered to trade back above $8,000 after tumbling as much as 13 percent from Friday. West Texas oil fell toward $62 a barrel. — Bloomberg
