Wall Street is expected to open at least 0.5% lower today following earlier falls in Asian and European markets and a 1.6% slide in the FTSE 100 in London. The falls have been sparked by the uncertainty following the UK's Brexit vote. 

"We've seen strong selling interest across the board this week," said Michael Hewson, chief market analyst at CMC Markets in London. 

"While some have speculated that some 'Leave' voters may have undergone some form of buyer's remorse, it would seem that the same could also be said of the investors who took part in last week's stock market rebound." 

Later today the US Federal Reserve release the minutes of its June meeting and investors will be looking for clues as to when it might raise interest rates.

A "Disneyland-sized" lorry park intended to ease tailbacks caused by Operation Stack on the M20 will open next summer at Stanford West, Kent.

During Operation Stack, which was in force 32 times last year, the motorway was turned into an HGV park for up to 5,000 lorries.

Critics have accused the government of being "too hasty" in its plans.

Stack was activated last year when cross-Channel services were disrupted by the Calais migrant crisis and French ferry worker strikes. Read more here.

Markit has cut its forecast for FTSE 100 dividends payouts for 2016 and 2017 by £1bn following the Brexit vote, with banks, housebuilders, insurers and airlines the worst affected.

However, for the bluechips that pay their dividends in dollars the outlook is more benign. They include HSBC, Shell, BP, AstraZeneca, Rio Tinto and BHP Billiton; their shares have outperformed the broader market since the referendum decision.

HSBC has cut its target price on Tesco from 240p to 195p; the shares are now trading at 162p, down more than 8%.

The bank's analysts now rate Morrisons as "reduce" - its shares are now down 7% at 172.8p.

Speaking of supermarkets, a gloomy note from HSBC has sent shares in Tesco and Morrisons tumbling 8% and 6% respectively. 

"We expect that Tesco has lost a lot of its buying power and position over recent years due to mismanagement," the bank's analysts said. "We downgrade [it] to 'hold' from 'buy' as short-term sentiment would be against the sector." 

Sainsbury's is off 3.4%, as it happens.

Sainsbury's is holding its annual meeting in London today and the Guardian's Sarah Butler tweets:

The supermarket's shares are down 3.5% today and have fallen more than 16% this year.

The Serious Fraud Office said it would seek the retrial of two former Barclays traders after a jury failed to reach a verdict on whether they had been part of a conspiracy to rig global Libor interest rates. 

"The SFO has today announced that it is seeking a retrial of Stylianos Contogoulas and Ryan Michael Reich," the SFO said.

On Monday three former Barclays employees were found guilty of rigging Libor between 2005 and 2007.

Jay Merchant, 45, was convicted unanimously at Southwark Crown Court of manipulating the key financial rate. Jonathan Mathew, 35, and Alex Pabon, an American 38 year-old, were found guilty by majority verdict after a ten-week trial. The trio will be sentenced on Thursday.

Times leisure correspondent Dominic Walsh tweets:

Sterling continues to make up some of the losses it suffered earlier in the day to be down 0.6% at $1.2949 after sinking as low as $1.2798. That is, of course, quite some distance from its pre-referendum level of $1.50.

A quick update on what's going on in London trading - and now shares are down slightly once more. 

The FTSE 100 is down 0.3% at 6,528 points, while the FTSE 250 has regained some ground to be down 0.9% at 15,593 points.

That's not as bad as Paris and Frankfurt, which have both fallen about 1.6% today.  

Yields on German government 10-year bonds have sunk even further and are now below minus 0.2% for the first time.

More on the fall in sterling, this time from John Browett, chief executive of the homeware retailer Dunelm.

"Obviously it will feed through to prices if it stays at these low levels, but most companies will be hedged out for six to 12 months - we certainly are for the next 12 months, in fact even 18 months - so you don't see an immediate increase in prices," he tells Wake up to Money. 

"Then, of course, the other thing is it depends entirely what happens in the general economy that's a much bigger effect, although the biggest impact in our business is actually the weather rather than the short-term exchange rate falls."

Japan's largest brokerage Nomura has downgraded its outlook on Hong Kong for 2016 and 2017 in the wake of the Brexit decision.

It expects the Asian financial centre to fall into a recession this year as financial transaction volumes reduce "significantly" and China's economy continues to slow.

Hong Kong's 2017 GDP growth forecast was also cut to 0.5% from 1.5%.

"Hong Kong is the most vulnerable economy in the region to the fallout of the Brexit vote," Nomura said.

New car registrations fell for only the second time in more than four years in June, with a 0.8% decline year-on-year to 255,766 units, the Society of Motor Manufacturers and Traders said.

The trade body said it was too early to link the fall to the Brexit vote, however. 

Ratings agency Fitch said on Tuesday that there will probably be a decline in UK car sales due to slower economic growth and weaker consumer confidence.

The price of gold has hit its highest level for more than two years as investors' jitters about the Brexit vote sent them towards the safe haven asset.

Spot gold touched its highest since March 2014 at $1,371.40 before slipping back to be up 0.8% at $1,366.86 an ounce. It surpassed the $1,358.20 mark hit on June 24 in the immediate aftermath of the referendum vote.

Will the sterling slide in the wake of the Brexit vote affect consumer spending - which is crucial for the UK economy - and make goods more expensive? 

Economist John Glen, from Cranfield School of Management, tells Wake up to Money that some goods have to be imported as they are not produced here, so if the price goes up there is less disposable income to spend elsewhere.

"Of course a reduction in the value of the pound means that we can export more. So those people who are working in industries that are exporting are going to find an increase in demand for the goods and services that they're producing and an increase in employment in those areas," he adds.

Aviva is one of the firms that has suspended withdrawals from its commercial property fund. The insurer's shares have fallen more than a quarter this year but Mark Wilson, chief executive, has told investors that its fundamentals are sound. 

"Our balance sheet is strong and resilient and we are a simpler, focused group with excellent franchises. This is a strong foundation from which to grow profits, cash-flow and dividends over the coming years. Although it is too early to quantify the precise impact of Brexit, we are confident we can continue to grow," he said.

Aviva also stands to benefit from weaker sterling.

Although the insurer plans to increase the dividend payout to 50% next year, but wants to see what happens to markets before doing so.

Shares are down 2.6% in morning trading.
