MADRID, March 7, 2026, 08:27 CET
Spain’s IBEX 35 notched its steepest weekly drop since 2020, with Bolsas y Mercados Españoles (BME) showing the blue-chip index at 17,074.40 on Friday—down roughly 7% from last week’s close at 18,360.8. A surge in oil prices fueled inflation jitters, and traders dumped risk, putting heavy pressure on one of Europe’s more resilient markets, according to Reuters/LSEG data. 1
This shift is notable. Madrid’s IBEX, after all, had already pushed past its 2007 high back in October and, as of March 5, was still showing a gain of over 30% from a year ago—performance fueled by its heavy banking sector and Spain’s relatively strong local economy. 2
The same bank-heavy positioning looks exposed now. Morgan Stanley, for its part, dropped its forecast for any European Central Bank rate cuts in 2026 this week. Spanish central bank governor Jose Luis Escriva also weighed in, calling a rate move at the next meeting “very unlikely.” The war’s hit to oil prices has muddied the inflation, growth, and valuation picture, leaving little clarity for investors. 3
Monday packed a punch. European stocks slid for their sharpest single-day drop in three months, while Madrid—heavy on financials—saw its worst daily loss since April’s tariff jolt. Banks such as Santander slumped between 3% and 5%. Oil? Up as much as 13%. 4
Wednesday offered a brief breather, but the mood didn’t stick. The IBEX climbed 2.5% as buyers dipped back in, grasping at faint de-escalation hopes. Santander and BBVA helped drive a 2.3% rally among European banks, though the gains fizzled by Friday. “The merest whiff” of resolution was enough to jolt shares, said Kathleen Brooks, research director at XTB, but she cautioned fresh headlines could still trigger sharp moves. 5
Pain spread further by Friday. The STOXX 600 dropped 5.5% for the week—its steepest fall in nearly a year. Frankfurt and Paris both racked up their heaviest weekly losses since April last year, and Madrid recorded its worst week in four years. 1
Ciaran Callaghan, who leads European equity research at Amundi, warned that Europe faces greater exposure to rising oil prices, leaving the region vulnerable to what he called a “stagflationary environment”—a mix of sluggish growth and persistent inflation. Over at Edward Jones, senior global strategist Angelo Kourkafas pointed out that the jump in oil was creating a “difficult position” for the U.S. Federal Reserve and could limit gains in job growth. 1
BME highlighted an index reshuffle late in the week. The Technical Advisory Committee announced Aedas Homes will exit both the IBEX Small Cap and the IBEX Top Dividendo—BME’s index focused on dividends—effective March 9, following Neinor DMP BidCo’s takeover reaching over 90% acceptance. The change takes effect after Friday’s close. 6
Crude prices are the next factor in focus. Brent jumped 27% this week, according to Reuters, while ECB policymakers signaled they aren’t ready to adjust rates just yet, despite renewed inflation jitters triggered by the energy surge. “Market shocks tied to conflicts usually settle down after a few months,” Candriam’s chief investment officer Nicolas Forest said. But if oil hits $100 a barrel, he warned, “that’s another story.” 7
So far, it’s a repricing story—not a freeze-up. “Nothing that gums up the works,” said Kit Juckes, Societe Generale’s head of FX strategy, even as stocks got dumped and the dollar caught a bid. For Madrid, though, banks make up a big chunk of the market, so if this conflict drags into next week, the city’s exposure stands out. 8
