Wait to see whether any legislation that had already started to go through parliament to help reform regulation and financial services will be abandoned or will continue its journey once parliament is back.
That's a lot of waiting, and generally, financial services companies and consumers alike do not like having to wait.
Positive glimmers?
But perhaps there might be some hope in the form of market movements over the next couple of days.
Sterling has continued its incremental strengthening against the US$ - up a minuscule amount again to 1.2769 today as at 8am this morning (Friday July 5).
Likewise, the stock market remained buoyant, with the FTSE 100 holding around 8,270 at market opening today, compared with 8,241.26 at close yesterday (July 4).
As a bellwether of sentiment, it seems markets are unbothered by the Labour landslide.
Indeed, as Lindsay James, investment strategist at Quilter Investors said, markets have had the best part of three years to get comfortable with the idea of a Labour government.
She says: "With political turmoil hitting other developed economies at the same time, this huge majority may present the UK to investors as somewhat of a political safe haven – a known quantity that should give businesses confidence in the environment they operate in.
"If Labour can present an energetic vision of a new centrist government that enjoys considerable breadth of support, it should be a good starting point for the domestic economy.”
Clearly, the economic backdrop is still fragile. The UK has a large fiscal deficit, the debt to GDP ratio is wide and the gilt market is more sensitive than a tube of Colgate.
This means Labour has to avoid the temptation to come in like a lion. The scale of their win gives them, as James pointed out, a mandate to "reprioritise and reshuffle existing spending and taxation meaningfully".
Whether they do this in a way that supports and grows the UK economy over the next four to five years remains to be seen.
For now, the old mantra rings true: stay calm, and carry on.
