By Friday 6 March, what began as a wobble in energy markets had turned into a full‑blown repricing. Brent settled near $93 while WTI closed just under $91, capping the strongest weekly surge since 2020 as shipping through the Strait of Hormuz stalled. The move left crude up roughly 27% since the conflict began last weekend. Reuters data put Brent’s Friday settlement at $92.69, up 8.5% on the day. (investing.com)

The catalyst for the second leg higher was guidance from Qatar’s energy minister, Saad Sherida al‑Kaabi, who told the Financial Times that if war conditions persist, Gulf exporters could be forced to halt shipments within weeks and crude could climb towards $150. Multiple outlets carried the warning on Friday, underscoring how quickly pricing is now reacting to supply risk. (business-standard.com)

Crucially, insurance premia and crew safety concerns are doing much of the closing. Iran’s formal notice is patchy, but shipowners, charterers and ports are effectively self‑regulating traffic away from the choke point. West of England P&I described the reduction as commercial self‑restraint rather than legal closure, while logistics bulletins logged carriers suspending new bookings across the Gulf. (westpandi.com)

The inflation pulse is not limited to crude. Refined products and inputs to everyday goods are ratcheting up: European jet fuel and diesel jumped to multi‑month highs this week, while urea-vital to fertiliser supply chains-has surged to the strongest prints since S&P Global began several of its series last year. That combination tightens farm‑to‑fork costs and raises near‑term CPI risks. (investing.com)

That timing jars with the UK’s Spring Forecast. The OBR published its Economic and fiscal outlook on Tuesday 3 March using commodity paths that looked reasonable at Monday’s close. By the next day, the OBR’s own slides noted spot oil was already around 20% above forecast and spot gas about 25% higher; by Friday, Brent was closer to $93. In other words, the baseline moved under policymakers’ feet in four trading sessions. (obr.uk)

UK wholesale gas has lurched higher in sympathy. Market reports put National Balancing Point prices around 135p/therm late in the week after an intraday spike near 151p-levels last seen in early 2023 as Europe scrambled for LNG. Even if those prints ease back, futures curves now embed more persistence than they did a week ago. (ecosavegasandpower.com)

Gilt markets have responded in familiar fashion. Ten‑year yields, which the OBR assumed around the mid‑4s, pushed back toward 4.6% this week and briefly tested higher levels intraday as investors re‑priced inflation risk. Analysts note the UK’s reliance on gas for heating and power, plus relatively thin storage, tends to make gilts more sensitive when energy spikes. (tradingeconomics.com)

That shift is already leaking into household finances. Lenders including Nationwide, HSBC, Virgin Money, Coventry Building Society and NatWest have announced rate changes, with selected fixed deals moving up by as much as 0.25 percentage points. Moneyfacts and industry brokers describe a fast‑moving repricing cycle rather than a race to the bottom-so no mortgage “price war” while funding costs are this jumpy. (mortgagesolutions.co.uk)

Rate expectations are resetting too. A week ago, markets were leaning heavily toward a March Bank of England cut. By Friday, pricing had swung the other way, with some trackers showing single‑digit to low‑20% odds of an immediate move as traders opted to wait for clarity on energy and inflation. The next MPC decision falls on Wednesday 19 March. (theguardian.com)

The geopolitical path matters for all of this. President Donald Trump has floated a four‑to‑five‑week timeline-while saying the US can go “far longer”-and the past six days have seen strikes or incidents reach energy facilities and ports from Bahrain and Qatar to areas near Dubai’s Palm and waters off Kuwait. That pattern keeps a risk premium in freight, fuel and credit until shipping lanes normalise. (apnews.com)

For UK investors and SME owners, the near‑term playbook is practical rather than heroic: refresh cash‑flow assumptions using higher pump and utility costs; check hedges and fuel surcharges in contracts; and watch the five‑year swap and 10‑year gilt for the mortgage and capex signal. If Hormuz stays constrained, Brent could still test $100+ in coming sessions; if routes reopen, the risk premium can fade quickly-but until then, caution is the right default. (investing.com)
