Currency markets and equity markets are pricing the same political event in opposite directions. That gap is where active traders need to be paying attention this morning.

• EUR/USD touched $1.1160 Monday, its weakest since May 2025, before recovering to around $1.1220 in Tuesday’s Asian session.
• French 10-year OAT yield briefly reached about 4.9% to 5.0% on October 1, pushing to its highest level since 2002, with the OAT-Bund spread around the mid-140s to low-150s basis points.
• The OAT-Bund spread widened by roughly 34 basis points in about a week, one of the sharpest weekly moves in years, and has been trading wider than comparable spreads for Italy and Greece.
• IBEX 35 rose 1.12% Monday; it added about 1.20% Tuesday to reach roughly 19,532.
• Santander gained 4.42% Monday; BBVA posted H1 2026 net attributable profit of €6.05 billion, up about 11% year-over-year (and up 10% at constant exchange rates).
• Spain’s Nov. 29 election adds EU budget uncertainty, with Politico reporting overnight that the vote makes an end-2026 long-term budget deal less likely.

Two Markets, One Event

Pedro Sánchez called a snap election for November 29 after lawmakers rejected his emergency housing proposals, a core issue for his supporters. He leads a fragile left-wing coalition reliant on numerous smaller regional parties, which has made it difficult to pass reforms.

The forex market treated this as incremental risk on top of a deteriorating eurozone backdrop. The euro touched $1.1160 on Monday, its weakest since May 2025, before paring some losses.

Spain, though, is secondary to France in the bond market. France’s 10-year OAT-Bund spread rose into the mid-140s to low-150s basis points, with the OAT yield briefly nearing 5%, the highest since 2002. The France-Germany 10-year spread widened roughly 34 basis points in about a week, one of the sharpest weekly moves in years. The OAT-Bund spread has also been trading wider than Italy’s and Greece’s. Separately, France’s public debt has been discussed as rising toward 121.7% of GDP in 2027, and official projections have put annual debt-service costs around €91 billion in 2027.

France remains the bigger issue: OAT-Bund spread acceleration and fiscal anxiety are clearly bleeding into the currency. Spain adds political noise, not sovereign contagion risk at this scale.

The IBEX-EUR Divergence

Spanish equities are effectively voting that this is a French problem, not a Spanish one. Spain’s main index rose to roughly 19,532 on October 6, gaining about 1.20% from the previous session. The banking sector led: Santander gained about 1.9% Tuesday, with Merlin Properties up about 3.2%.

The underlying fundamentals explain why institutional money is staying in Spanish banks rather than fleeing them. Santander’s H1 2026 revenue rose 6% to €30.8 billion, with strong net interest income and fee growth. The bank achieved an underlying return on tangible equity of 15.6%, with underlying earnings per share up 20%. BBVA’s picture is similarly constructive: BBVA posted net attributable profit of €6.05 billion in H1 2026, up 11.1% year-over-year (up 10.0% at constant exchange rates). ROTE reached 21.7% in Q1.

A euro trading near 17-month lows actually supports these banks’ international revenue translation, particularly Santander’s significant Latin American exposure.

Technical Framework

EUR/USD is trading below its 200-day moving average and has broken the $1.1250 support that held through most of Q3. The next structural support sits around $1.1000, a level last tested in late 2024. Momentum indicators remain negative. Any short-squeeze back toward $1.1300-$1.1350 would run into heavy supply given the four-week losing streak.

The IBEX is trading above its 50-day average. A reversal in EUR/USD sentiment or a deterioration in OAT spreads beyond 160 basis points could pressure the index back toward the 18,800-19,000 zone. The index’s outperformance relative to the euro suggests domestic equity traders are pricing a relatively contained Spanish political outcome.

Scenario Modeling

Bull Case: France’s €43 billion fiscal savings package advances substantially intact, the OAT-Bund spread compresses back below 110 basis points, and EUR/USD recovers toward $1.1400. Spanish polls tighten, reducing the tail risk of a hard-right government overturning EU budget commitments. IBEX presses toward 20,000; Santander and BBVA maintain their outperformance.

Base Case: EUR/USD remains range-bound between $1.1100 and $1.1300 through November, with the OAT-Bund spread consolidating in the 130-150 basis point corridor. Spanish political uncertainty suppresses new institutional inflows into IBEX but does not trigger a selloff. Spanish bank equities hold their fundamental support, trading in line with European bank peers.

Bear Case: France’s minority government fails to pass its budget in recognizable form. If the market reads the passed package as insufficient, the 130-basis-point spread becomes a floor, not a ceiling, and ECB options narrow further before the presidential election resets the political calendar. EUR/USD breaks below $1.1000. IBEX corrects 5-8% toward 18,000 on contagion fears, with Spanish bank spreads widening alongside OATs.

Active Trader Considerations

The divergence between EUR/USD and the IBEX creates two distinct positioning environments. Traders focused on currency are dealing with a structurally weakening euro where each political event adds asymmetric downside. Equity traders in Spanish banks are working with strong fundamentals but must monitor OAT spreads as the primary risk variable, not Sánchez’s poll numbers.

Key levels to watch: EUR/USD $1.1100 as near-term support; OAT-Bund spread 160 basis points as a stress threshold; IBEX 19,000 as the first meaningful technical floor. The Nov. 29 Spanish vote date will intensify volatility windows in late November, but the OAT market is the instrument pricing systemic risk right now. Position sizing should reflect that the macro driver is Paris, not Madrid.

Preparation, not prediction. The IBEX-EUR split will resolve one way or the other. Know which side of that trade you are on before it does.
