The London market is caught in a familiar vice this morning, squeezed by the twin pressures of frothy tech valuations and geopolitical instability. The FTSE 100 opened lower, mimicking Wall Street's retreat as investors digested a fresh wave of anxiety over the artificial intelligence sector. Hopes of a soft landing are fading faster than a day trader's patience, replaced by the cold reality that central banks are running out of road.
The tech sell-off, led by a sharp decline in US mega-caps, has spilled into European bourses. London's heavyweight miners and energy stocks initially offered some buffer, but even they succumbed as oil prices spiked on renewed hostilities in the Middle East. A series of attacks on shipping lanes and infrastructure in the region has reignited supply fears, sending Brent crude above $85 a barrel. For an economy already grappling with stubborn inflation, this is the last thing the Bank of England needed to see.
Gilt yields are creeping higher, reflecting the market's growing unease about fiscal discipline. The 10-year yield touched 4.2%, a level that historically signals a vote of no confidence in the government's ability to manage debt. With a general election looming, neither party is talking about austerity, but the bond market will demand it eventually. Capital is fleeing to the dollar, pushing sterling below $1.25, which only adds to the import cost pressures that the consumer is already feeling in their weekly shop.
The root cause of this volatility is a simple mismatch of expectations. For months, the market priced in a series of rate cuts beginning in June. Now, with inflation proving sticky and employment data resilient, those bets are being unwound. The Federal Reserve has signalled patience; the ECB is similarly cautious. And the Bank of England? It is stuck between a rock of high service inflation and a hard place of stagnant growth.
The tech angle is particularly galling. AI optimism drove a massive rally in the first quarter, but the reality of monetisation is setting in. Companies are spending billions on infrastructure with no clear path to profitability. That is a dangerous game when the cost of capital is no longer zero. When the tide goes out, we see who is swimming without trunks.
Meanwhile, the Middle East escalation adds a layer of unpredictability that markets loathe. Unlike the trade wars of yesteryear, this is not something that can be solved with tariffs or negotiation. It is a raw supply shock hitting an economy that is already fragile. The FTSE's composition, heavy on commodities and financials, offers some insulation, but not enough to escape the global downdraft.
This is the moment when fiscal responsibility matters. Governments that used the low-rate era to pile on debt are now exposed. The UK's fiscal headroom is minimal, and the next chancellor will inherit a Treasury that is more straitjacket than safety net. The market is watching, and it will not forgive profligacy.
As I write, the FTSE 100 is down 0.8%, with the mid-cap FTSE 250 faring worse, off by 1.3%. Volume is heavy, suggesting institutional selling. The VIX, Wall Street's fear gauge, is above 20, and the equivalent in London is flashing amber. For now, the safest asset is cash, but that earns nothing. The bottom line: uncertainty is the only certainty, and that is never good for equities.
