SSE plc (LON: SSE) was the standout riser in the FTSE 100 on Tuesday April 21, gaining 3.6 percent to emerge as the session’s top performer as investors rotated into defensive infrastructure names amid mounting anxiety over the Iran ceasefire deadline and continued oil price pressure. Centrica plc (LON: CNA) gained 1.76 percent in sympathy, and the two utilities led a broader shift in sector allocation within the index as the Iran situation cast a shadow over risk appetite heading into Wednesday’s ceasefire expiry.
SSE’s move reflected a combination of idiosyncratic and macro factors. The company, which operates regulated electricity networks in Scotland and the south of England alongside a significant renewables generation portfolio, benefits directly from the current energy price environment and from investor appetite for regulated infrastructure assets whose returns are contractually linked to inflation.
With crude oil Brent sitting above $90 per barrel and the Citigroup team warning on Tuesday that prices could reach $110 per barrel if the Strait of Hormuz remains disrupted for another month, utilities are attracting capital from investors seeking to reduce exposure to the broader economic sensitivity of the market while retaining an indirect energy hedge.
The UK employment data released on April 21 provided a constructive macro backdrop for the session. UK unemployment fell to 4.9 percent, below the previous reading of 5.2 percent and below market expectations, while wage growth including bonuses slowed to 3.8 percent — a combination that points to a labour market that remains resilient without generating the kind of wage-driven inflationary pressure that would make Bank of England rate cuts more difficult to deliver.
For SSE and other regulated utilities, slower wage inflation is directly relevant to their operating cost base, which is heavily weighted toward labour across network maintenance and grid expansion programmes.
The FTSE 100 index closed April 21 at approximately 10,498, having given back morning gains in the second half of the session as reports emerged that Vance’s trip to Islamabad had been paused due to a lack of Iranian commitment to attend the talks.
The index’s year-to-date performance remains positive, with analysts forecasting record FTSE 100 dividends of approximately £88 billion in 2026, equivalent to a forward yield of around 3.3 percent, which continues to underpin the index’s attraction for income-focused International allocators relative to US equities on a pure yield basis.
