And whilst no-one is suggesting that it will take quite as long to understand the consequences of the EU referendum, it does appear safe to conclude that we are some time away from knowing, with certainty, what the UK's future relationship with the EU looks like.
In its most recent Financial Stability Report, the Bank of England recognised that it will take some time for the UK to establish new trading relationships with the EU and the rest of the world and that "some market and economic volatility is to be expected as this process unfolds".
That said, it's important that we do not immediately equate some market volatility with a full blown economic crisis. The range of UK GDP estimates which have been issued post the referendum are still generally projecting growth in 2017, albeit at a lower rate than was previously the case. This might be contrasted with the fall in GDP of 6.3% which took place over 5 quarters during the 2008/9 financial crisis. As things stand, it appears to be more a case of choppy waters ahead rather than an incoming tidal wave.
For those living, working or investing in Scotland, there are also the questions which are now being posed around Scotland's position within the UK - or Indyref 2, as the media shorthand has now dubbed it.
Again, it seems reasonable to take the view that we will not have a definitive answer to these questions imminently. Indeed, if Indyref 2 is being driven by there having been a material change in the nature of the UK's relationship with the EU, then it would seem reasonable to await clarification on the specific nature of that future relationship, before attempting to crystallise what this then means for Scotland's relationship with the rest of the UK.
Amidst this uncertainty, the one thing we do know is that the world will keep turning. The planning and decision making which businesses and individuals make about the future will still require to be made and whilst there is an understandable desire to take stock, few businesses or individuals will be willing to sit on their hands forever.
We are a firm which works across a wide range of sectors and with a wide range of clients - from large PLCs, owner-managed businesses, major clearing banks and angel investors to housebuilders, property developers, central and local government and private individuals. This allows us to take a broad view, whilst also seeing how the impact of Brexit-related issues can be quite different both between and within specific sectors.
So our task is to work with our clients to assess what it means for each of them specifically, with the benefit of what we can see happening across the range of sectors we work in.
At the core of what we have always done for our clients is the weighing up of different sets of risks and advising on an optimum way forward in light of those risks. The nature of the risks may have changed but the need to help our clients navigate them remains the same.
We'll continue to share our thoughts on what Brexit means in different sectors as things develop but if you'd like to have a more specific discussion at any point please do get in touch with me or your usual Morton Fraser contact.
