U.S. stock index futures fell Friday as a plunge in shares of Deutsche Bank in Europe raised investor fears about the banking sector once again. Futures tied to the Dow Jones Industrial Average slid 333 points, or 1.03%. S&P 500 futures dipped 0.84%, while Nasdaq-100 futures were 0.5% lower. Deutsche Bank’s U.S.-listed shares slid about 11% in the premarket after the the German lender’s credit default swaps jumped, but without an apparent catalyst. The move appeared to raise concerns once again over the health of the European banking industry. Earlier this month, Swiss regulators forced a UBS acquisition of rival Credit Suisse. Shares of major U.S. banks were also under pressure. Bank of America, JPMorgan Chase and Wells Fargo fell more than 2% each. Meanwhile, Citigroup fell more than 3%. Regional bank stocks also declined, with the SPDR S&P Regional Banking ETF falling 2%. “The Silicon Valley Bank problem brought more attention on banks,” Larry McDonald, founder of the Bear Traps Report, said Friday on CNBC’s “Squawk Box.” “And so, banks like Credit Suisse and Deutsche Bank that have been horribly, horribly managed for decades — and we’re talking about really poor management and horrible decisions — all of a sudden, investors around the planet, focus on that.” Wall Street is coming off a volatile session Thursday that ultimately ended with the major averages posting solid gains. The Nasdaq Composite posted the largest gain, at 1%, as technology shares continued to rally on a hunch that interest rate hikes would be coming to an end. The S&P 500 ended around 0.3% higher, while the Dow finished up 0.2%. For the week, the Dow and S&P 500 are up around 0.8% each, while the Nasdaq has gained 1.4% through Thursday’s close. Investors continued to assess the Fed’s latest policy move announced this week. The central bank hiked rates by a quarter-point. However, it also hinted that its rate-hiking campaign may be ending soon. Meanwhile, Fed Chair Jerome Powell noted that credit conditions have tightened, which could put pressure on the economy. On Thursday, Treasury Secretary Janet Yellen said regulators are prepared to take more action if needed to stabilize U.S. banks. Her comments are the latest among regulators attempting to buoy confidence in the U.S. banking system in the wake of the Silicon Valley Bank and Signature Bank closures. Asia-Pacific markets were mixed on Friday, as investors weigh remarks from U.S. Treasury Secretary Janet Yellen, who said federal emergency actions to back up failed regional banks could be used again if necessary. The Hang Seng index led losses in the region, trading 0.65% lower, but the Hang Seng Tech index was up 0.61%. In mainland China, the Shanghai Composite closed 0.64% down at 3,265.65, but the Shenzhen Component was up 0.25% to end at 11,634.22. South Korea’s Kospi fell 0.39% to finish at 2,414.96, but the Kosdaq traded 1.47% higher to end at 824.11. In Japan, the Nikkei 225 was down 0.13% to close at 27,385.25 and the Topix finished 0.1% lower at 1,955.32. Australia’s S&P/ASX 200 was 0.19% lower, ending the day at 6,955.2. Oil prices fell on Friday, extending the previous day’s losses, on worries about potential oversupply after U.S. Energy Secretary Jennifer Granholm said refilling the country’s Strategic Petroleum Reserve or SPR may take several years. Brent crude futures slid $2.39, or 3.2%, to $73.52 a barrel, while U.S. West Texas Intermediate crude futures dropped $2.40, or 3.4%, to $67.56 a barrel. Gold rose but remained in a tight range as the metal’s longer-term prospects were bright given bets for a pause in U.S. interest rate hikes. Spot gold was up 0.1% at $1,994.53 per ounce, but was still locked in a tight $14 range. U.S. gold futures also rose 0.1% to $1,997.90. Prices gained in the last two sessions after the Federal Reserve raised rates by an expected quarter of a percentage point, but signaled it was on the verge of pausing. Lower rates burnish appeal for the zero-yield bullion.
