• Israel's Defense Minister Israel Katz has dismissed Iran's warning against striking Lebanon, signaling continued military operations.
  • The exchange heightens geopolitical risk in the region, with implications for energy markets and regional stability.
  • Hezbollah remains tied to Iranian backing, raising the prospect of a broader conflict if miscalculations occur.

Israel pushes back against Iranian threats

Israel's Defense Minister Israel Katz on Thursday rejected Iran's warning not to attack Lebanon, vowing to continue operations against Hezbollah. "Israel will act wherever necessary to defend its security," Katz said in a statement, according to people familiar with the matter. The remarks come after Iran's Foreign Minister warned that any Israeli strike on Beirut would trigger a "strong response" from Tehran and its allies.

Military posture remains aggressive

Israeli commanders have emphasized that the Lebanon front remains active, with cross-border exchanges continuing despite truce efforts. Troops are conducting operations in southern Lebanon in response to rocket fire, signaling no let-up in pressure. The Israeli military declined to comment on specific operations but noted that "preparedness for all scenarios" remains high.

Iranian stance hardens

Tehran has conditioned diplomacy with the US on regional concessions while warning that an attack on Beirut could escalate into broader conflict. "Iran will not abandon Hezbollah," a senior Iranian official told Reuters under condition of anonymity. The message underscores Iran's aim to deter Israeli strikes while keeping the threat of retaliation through proxies alive.

Market implications

Geopolitical risk is driving volatility in energy markets, with Brent crude up 2% on Thursday amid concerns over supply disruptions. Shipping insurers are raising premiums for vessels in the Eastern Mediterranean. Regional stock markets are mixed, with Tel Aviv's TA-35 down 0.5% and Gulf bourses flat. Analysts warn that a broader conflict could push oil above $100 per barrel, though a de-escalation could reverse gains.

Diplomatic efforts falter

US and European mediators have struggled to broker a ceasefire, with both sides hardening positions. A senior US official said earlier this week that negotiations remain "fragile," and urged restraint. Hezbollah's leadership has tied any truce to a halt in Israeli operations in Gaza, complicating talks.

Outlook

The near-term risk of localized clashes remains high, with a nonzero chance of targeted strikes if red lines are crossed. Investors are watching for any ceasefire proposal or shift in military posture. Without a deal, the region risks a spiral of retaliation that could draw in Iran, Hezbollah, and other proxies.
