Imogen BennettThe FTSE 100 has been on a rollercoaster since February 2026, and searches for "stock market crash" in the UK have surged this week as investors nervously watch oil prices hover above $100 per barrel and geopolitical tensions in the Middle East show no sign of easing. If your savings, pension, or investment portfolio is exposed to equity markets, this is the moment to think clearly — not panic. Here is what a wealth management adviser would tell you right now.
What Is Actually Driving the Market Turbulence
The current volatility has two main engines: the Iran-Israel military conflict that escalated in late February 2026, and the ongoing uncertainty around US trade tariffs.
When Israel and the United States launched strikes against Iranian targets on 28 February 2026, oil markets reacted immediately. Brent crude surged from around $70 per barrel to above $100 by early April — a rise of more than 40% in five weeks. Iran produces 3.6 million barrels per day, roughly 3.5% of global supply. Disruptions to Strait of Hormuz traffic alone threaten a further 10 to 20 million barrels per day of global shipping.
UK wholesale natural gas prices rose 75% between late February and late March 2026, according to energy analysts tracking commodity markets. Chemical and steel manufacturers have already begun imposing surcharges of up to 30% on their products to offset rising electricity and feedstock costs.
Compounding this, Trump's tariff announcements — threatening a 10% baseline rising to 25% for multiple countries — have added a secondary layer of uncertainty for UK-listed multinationals with global supply chains.
The FTSE 100 Is Not the S&P 500 — and That Matters
Here is something many UK investors do not fully appreciate: the FTSE 100 is structurally different from US indices, and that difference is protecting British investors right now.
More than 60% of FTSE 100 constituents are in defensive sectors: energy majors, mining companies, defence contractors, pharmaceuticals, and financial services. These sectors either benefit directly from rising commodity prices or are relatively insulated from consumer spending cycles.
The FTSE 100 opened April 2026 at 10,337, and as of 3 April stood at 10,436 — having already recovered more than 5% from its March lows. By contrast, the S&P 500 and Nasdaq 100 remain down 10% or more from their January peaks.
Defence stocks have been a standout: BAE Systems rose 1.3% on days when broader markets fell. Gold miners gained 5.5% in a single week in mid-March as investors sought safe-haven assets.
Five Things Wealth Managers Are Telling Clients Today
1. Stay invested, but rebalance now. The worst investment decisions are made during volatility peaks, not before them. A wealth adviser would review your current allocation — heavy exposure to consumer-facing businesses, retail, or industrial sectors carries more risk than defensives. Rebalancing does not mean selling everything; it means ensuring your portfolio reflects the current risk environment.
2. Lock in bond yields while they are elevated. The Bank of England was widely expected to cut rates three times in 2026. Energy price shocks have reversed that expectation entirely. According to the Bank of England's February 2026 Monetary Policy Report, inflation was already under pressure before the Middle East conflict. With markets now pricing in potential rate hikes rather than cuts, UK government gilts and investment-grade corporate bonds are offering real yields above 4–5% for the first time in years. This window may not stay open long.
3. Review your mortgage exposure. Barclays and Nationwide withdrew their sub-4% fixed-rate mortgage deals in March 2026. Average mortgage rates have climbed above 5% for the first time since late 2024. If your fixed-rate deal is expiring in the next six to twelve months, speaking to a financial adviser now — rather than when rates are announced — gives you more options.
4. Consider a modest gold allocation. Gold has historically outperformed in geopolitical crises. Between February and April 2026, gold rose approximately 12% in sterling terms as the pound weakened. A 5–10% allocation to gold or commodity funds is not a speculative bet — it is a standard portfolio hedge against inflation tail risk.
5. Do not overreact to tariff noise. UK investors with holdings in FTSE 100 multinationals should note that a weaker pound — which typically accompanies periods of global uncertainty — actually boosts reported earnings for companies that earn revenue in dollars or euros. The tariff effect is real but uneven; sector-by-sector analysis matters more than a blanket sell-off.
What a "Crash" Would Actually Look Like
The term "stock market crash" is getting heavy use this week, but context matters. A technical bear market is defined as a 20% decline from peak. The FTSE 100 is currently roughly 4% below its January 2026 high. That is a correction, not a crash.
The scenario that wealth managers are actually stress-testing is a prolonged oil price shock above $110 per barrel combined with a Strait of Hormuz closure. HSBC Asset Management's April 2026 Investment Monthly notes that in this scenario, UK inflation could rise an additional 0.7 percentage points above baseline forecasts — meaningful but manageable compared to the 2022–2023 energy crisis.
The scenario that nobody is pricing in yet — a rapid de-escalation in the Middle East — would likely trigger a sharp equity rally. Investors who sold into fear would miss that recovery.
When to Seek Professional Advice
The current environment is exactly when a wealth management adviser earns their fee. Not because they can predict whether markets go up or down — no one can — but because they can map your specific situation: your time horizon, your tax position, your liquidity needs, and your existing exposure.
If your portfolio has grown significantly in recent years and you have not rebalanced since 2024, this is the right moment. If you are within five years of retirement, your risk profile may need to shift regardless of market conditions.
