If you have asked for a sea freight quote in the last few weeks, you have probably noticed something frustrating. The number you were given at the start of the month is not the number you are being quoted now, and if you go back next week it may well have moved again. You are not imagining it, and it is not just your forwarder. Container rates on the big east to west trade lanes have been climbing since roughly the middle of May, and the increases have carried on right through June into July.
The good news is that this is a fairly well understood pattern once you know what is going on. In this piece we will explain, in plain English, why your quotes keep going up, why it has happened so early this year, and the practical steps you can take to keep your shipping budget under control before the latest round of July increases really bites.
Peak season turned up early this year
Every year there is a stretch, usually late summer into autumn, when everyone tries to move cargo at once. Retailers build stock for the run up to Christmas, importers top up ahead of the quieter winter months, and demand for container space outpaces the number of ships and boxes available. That is peak season, and when it arrives, rates go up.
What has caught a lot of shippers off guard in 2026 is the timing. According to freight data provider Freightos, spot rates on the main east to west lanes started climbing from around the middle of May, weeks earlier than a typical peak. The interesting part is what is driving it. Freightos points to surging demand rather than fuel prices as the main culprit this time round. In other words, a lot of cargo owners decided to move their goods sooner, all at roughly the same time, and the market simply could not absorb it without prices rising.
What the numbers actually say
It helps to put some figures against the feeling. The Drewry World Container Index, which is one of the most widely watched measures of global container spot rates, rose about 5 percent in the week to 25 June 2026, reaching roughly 4,166 US dollars for a standard 40ft container. Drewry noted that the increase was lifted largely by the Transpacific route, which is the Asia to North America trade.
That headline rate is a global composite, so what you pay into the UK from a given origin will differ, but the direction of travel is the same across the board. On top of the base rate, carriers pushed through their usual peak season tools in early June. These are General Rate Increases, or GRIs, which are broad price rises applied to a lane, and Peak Season Surcharges, or PSS, which are extra fees layered on during the busy stretch. Both Freightos and Drewry reported Asia to North Europe Peak Season Surcharges of around 1,000 US dollars per 20ft container coming into effect on 1 July. If your quote suddenly gained a new line item this month, that is very likely what you are looking at.
Why the increases keep spreading week to week
One quote climbing is annoying. Quotes climbing again and again feels relentless, and there is a reason for that too. When the main lanes get busy, carriers move ships from quieter secondary routes to cover the early peak. Freightos has flagged this shuffling of capacity as one reason rates on those secondary trades have nudged up as well. So even if you are not shipping on the busiest Asia to Europe or Transpacific lanes, you can still feel the knock on effect through less space and firmer pricing on your own route.
There is also an important point about why this is happening now. A good chunk of the extra demand has been linked to shippers bringing their bookings forward ahead of possible changes to US tariffs. Drewry has connected the frontloading of cargo to this uncertainty. That matters for how you read the situation, because some of the surge reflects timing rather than a permanent change in the market. Cargo that is being shipped now is cargo that will not need shipping later, which is worth bearing in mind when you plan the rest of your year.
Practical moves UK importers can make right now
You cannot control the global market, but you can control how exposed you are to it. Here are the steps that make the most difference for UK shippers.
Book earlier than you normally would. When space is tight, the shipments booked well ahead are the ones that get loaded and the ones that avoid the sharpest last minute pricing. Leaving it late during an early peak is the most expensive way to ship.
Look past the headline rate. The cheapest quote on paper is not always the cheapest shipment. Compare schedule reliability, the routing your cargo will actually take, and your exposure to surcharges like GRIs and PSS. This is guidance echoed by freight platform SeaRates, and it holds up well in a volatile market. A slightly higher rate on a reliable, direct service can easily beat a low rate that arrives late or picks up extra fees along the way.
Split your urgent stock across modes. If a portion of your order is genuinely time critical, moving that part by air while the rest travels by sea can keep your shelves stocked without paying premium sea rates on the whole consignment. It is a blend worth pricing up rather than dismissing.
Talk to your forwarder about space commitments. When rates are jumping week to week, a conversation about committing volume in exchange for more predictable space and pricing can be far more valuable than chasing the lowest spot rate every time you ship. This is exactly the kind of planning we are here to help with.
Frequently asked questions
How long will these higher sea freight rates last?
Nobody can give you a firm date, and we would be wary of anyone who claims to. What we can say is that a meaningful part of the current surge has been linked to shippers frontloading cargo ahead of possible tariff changes, which suggests some of it reflects timing rather than a permanent shift. Rates often ease once the early rush works through, but peak season itself typically runs into the autumn. The sensible approach is to plan your bookings as if firm rates will be with us for the summer, then reassess.
Should I switch some shipments to air freight?
For genuinely urgent stock, splitting part of an order to air can be worthwhile, because it keeps your critical lines moving without paying elevated sea rates on the entire consignment. It is rarely the answer for everything, since air freight costs more per kilo, but as a targeted tool during a squeeze it can protect both your service levels and your budget. We are happy to price up a sea and air blend so you can see the trade off clearly.
Why is my quote different from a rate index I read about online?
Indices like the Drewry World Container Index are global composites that track specific benchmark lanes, so they are excellent for spotting the overall direction of the market. Your actual quote depends on your origin, destination, cargo type, container size, timing and the surcharges that apply to your route. Use the indices to understand the trend, and use your forwarder to understand your number.
What is the single most useful thing I can do this week?
Book earlier and speak to your forwarder about your plans for the next few months. When space is tight, the shipments arranged well in advance are the ones that get loaded and avoid the sharpest last minute pricing. A short conversation now about your expected volumes lets us secure space and give you steadier pricing rather than reacting to a fresh increase every time you ship.
