This Week in Review | US-Iran Conflict, US Inflation, New UK Prime Minister (July 17, 2026)
This week in review covers three major developments: escalating US-Iran tensions and oil price increases, June's better-than-expected inflation data showing a 3.5% year-over-year deceleration, and Andy Bernham becoming the UK's next prime minister. The analysis emphasizes market resilience and forward-looking pricing despite near-term volatility.
Summary
The episode begins with US-Iran tensions, where President Trump reimposed a blockade on Iranian shipping following the announcement that a ceasefire was over. This caused oil prices to jump nearly 10% on Monday alone, climbing into the low 80s per barrel. However, the speakers argue this does not represent a radical shift, noting that businesses have adapted to energy supply constraints through increased pipeline usage, production diversification outside the Persian Gulf, and expanded US oil exports. They reference the 2022 Ukraine invasion as a historical comparison, which forced larger structural shifts and saw Brent crude peak at $133 before normalizing, whereas current oil prices at $80 are more moderate.
On inflation, the US Bureau of Labor Statistics released June's CPI data showing headline inflation decelerated to 3.5% year-over-year—lower than economist forecasts and marking the first deceleration in year-over-year CPI in 2026. The deceleration was broad-based, with energy costs and gasoline prices declining. While commentators warn July's numbers may be affected by the Iran escalation, the speakers emphasize that inflation is fundamentally a monetary phenomenon, and with global money supply growth remaining moderate, a sustained inflation spike is unlikely.
Finally, regarding the UK, Andy Bernham secured over 80% support from the Labor Party to become the next prime minister, officially taking office Monday. He inherits similar headwinds that faced his predecessor Starmer, and with the next general election not required until 2029, he must manage internal party factions and political gridlock. The speakers view this as a quiet positive for markets, as low expectations reduce negative surprise potential and open the door for positive surprises if policy proves less disruptive than feared.
Key Insights
- Businesses have adapted to energy supply constraints by ramping up pipeline use, boosting production outside the Persian Gulf, and increasing US oil exports, making the Strait of Hormuz less critical than it once was
- The 2022 Russian invasion of Ukraine forced far larger and more permanent structural shifts across global energy markets, yet Brent crude peaked at roughly $133 per barrel before normalizing relatively quickly
- Markets are forward-looking and actively weigh future conditions three to 30 months out rather than just today's headlines, and are already pricing in a future where the Strait of Hormuz plays a diminished role
- June's CPI deceleration to 3.5% year-over-year was broad-based with energy costs declining, marking the first deceleration in year-over-year CPI in 2026, despite economist forecasts for higher readings
- Low expectations for new UK Prime Minister Andy Bernham reduce the potential for negative surprises and open the door for reality to positively surprise if policy proves less disruptive than feared

Are Stocks Ignoring Iran War Risks?
Equity markets are increasingly ignoring Iran war risks as investors recognize the conflict's economic impacts remain contained.
