Why does the Iran nuclear deal matter for markets?

It can lower the oil risk premium by reducing supply and conflict fears. Cheaper energy supports margins, steadies inflation, and can ease rate pressures. That often lifts broad equities and credit. For UK investors, it can help fuel costs and reduce CPI risks, improving confidence across rate‑sensitive parts of the market.

How could this affect a UK portfolio today?

If talks progress, energy users like airlines, autos, and retailers may benefit, while energy producers could lag. We would keep diversified US exposure and favour quality cyclicals and cash‑rich tech. Review FX hedges on US holdings, as a softer dollar on de‑escalation headlines can offset equity gains for GBP investors.

What levels on the S&P 500 are important now?

We are watching the 50‑day average near 6,894 and the year high around 7,002. Holding above the Bollinger mid near 6,866 supports upside toward the upper band. An ATR near 59 points flags active intraday ranges, so plan entries and stops with those swings in mind.

What are the key risks to this view?

Talks can stall, sanctions may not ease, or rhetoric can spike. Any incident in the region can rebuild the oil risk premium fast. A stronger dollar on risk aversion could also weigh on US assets in GBP terms. Use clear risk limits and avoid concentration in single event paths.
