The most awkward flash-crash possible

When your stock exchange wipes 99.75 per cent off its own value in less than a second, it might be t

Felix Salmon shows us his chart of the day, from Zerohedge (click for big):

He explains:

What you’re seeing here is the price of shares in BATS, at 11:14 [Friday] morning [ET]. The white spots are trades: there are 176 of them altogether. They start just below the IPO price of $16, and then just fall lower and lower and lower until the stock is trading for mere pennies. But the key number you want to look at here is not on the y-axis. Instead, it’s the chart report at the very top:

Elapsed Time: 900 Milliseconds

BATS, which stands for Better Alternative Trading System (a name which will surely come to haunt them), is a stock exchange based in Kansas. While most American stocks are listed in one of the two big exchanges, NYSE or Nasdaq, there are multiple venues where stocks can be traded – around 50. These exchanges communicate with each other to work out a "national best bid/offer" (NBBO), which is kept consistent throughout the venues. At least, that's the plan.

What appears to have happened is that a "software bug" (BATS aren't particularly forthcoming with the details) severed, or otherwise corrupted, the link between BATS and the NBBO system for all stocks beginning with A or B. This combined with the high-frequency trading that operates heavily in BATS (indeed, which it was largely set-up to enable) to allow stocks to plummet in less than a second.

For the most part, no-one was hurt. The error was confined to the one exchange, which rolled back the transactions. We would have all learned a valuable lesson about the dangers of computer-aided trading, the proponents of a financial transactions tax would have another weapon in their armoury (high-frequency trading isn't financially viable with a financial transactions tax in place), and everything would go back to normal. We would have, were it not for an excruciating coincedence:

The share that is charted above is that of BATS itself - that is, the company running the stock exchange which suffered the glitch. Not only that, it is the value of BATS on the day it held its initial public offering. Awkward.

BATS the company was supposed to be the first one to be listed (as opposed to merely exchanged) on BATS the exchange. For a smallish company based in a suburb of Kansas City, that is quite a big power grab. Needless to say, it didn't go to plan. The IPO is now cancelled, and the company has "no plans" to try it again soon. Which is unsurprising.

Stability is essential to solve the pension problem

The new chancellor must ensure we have a period of stability for pension policymaking in order for everyone to acclimatise to a new era of personal responsibility in retirement, says 

There was a time when retirement seemed to take care of itself. It was normal to work, retire and then receive the state pension plus a company final salary pension, often a fairly generous figure, which also paid out to a spouse or partner on death.

That normality simply doesn’t exist for most people in 2016. There is much less certainty on what retirement looks like. The genesis of these experiences also starts much earlier. As final salary schemes fall out of favour, the UK is reaching a tipping point where savings in ‘defined contribution’ pension schemes become the most prevalent form of traditional retirement saving.

Saving for a ‘pension’ can mean a multitude of different things and the way your savings are organised can make a big difference to whether or not you are able to do what you planned in your later life – and also how your money is treated once you die.

George Osborne established a place for himself in the canon of personal savings policy through the introduction of ‘freedom and choice’ in pensions in 2015. This changed the rules dramatically, and gave pension income a level of public interest it had never seen before. Effectively the policymakers changed the rules, left the ring and took the ropes with them as we entered a new era of personal responsibility in retirement.

But what difference has that made? Have people changed their plans as a result, and what does 'normal' for retirement income look like now?

Old Mutual Wealth has just released. with YouGov, its third detailed survey of how people in the UK are planning their income needs in retirement. What is becoming clear is that 'normal' looks nothing like it did before. People have adjusted and are operating according to a new normal.

In the new normal, people are reliant on multiple sources of income in retirement, including actively using their home, as more people anticipate downsizing to provide some income. 24 per cent of future retirees have said they would consider releasing value from their home in one way or another.

In the new normal, working beyond your state pension age is no longer seen as drudgery. With increasing longevity, the appeal of keeping busy with work has grown. Almost one-third of future retirees are expecting work to provide some of their income in retirement, with just under half suggesting one of the reasons for doing so would be to maintain social interaction.

The new normal means less binary decision-making. Each choice an individual makes along the way becomes critical, and the answers themselves are less obvious. How do you best invest your savings? Where is the best place for a rainy day fund? How do you want to take income in the future and what happens to your assets when you die?

 An abundance of choices to provide answers to the above questions is good, but too much choice can paralyse decision-making. The new normal requires a plan earlier in life.

All the while, policymakers have continued to give people plenty of things to think about. In the past 12 months alone, the previous chancellor deliberated over whether – and how – to cut pension tax relief for higher earners. The ‘pensions-ISA’ system was mooted as the culmination of a project to hand savers complete control over their retirement savings, while also providing a welcome boost to Treasury coffers in the short term.

During her time as pensions minister, Baroness Altmann voiced her support for the current system of taxing pension income, rather than contributions, indicating a split between the DWP and HM Treasury on the matter. Baroness Altmann’s replacement at the DWP is Richard Harrington. It remains to be seen how much influence he will have and on what side of the camp he sits regarding taxing pensions.

Meanwhile, Philip Hammond has entered the Treasury while our new Prime Minister calls for greater unity. Following a tumultuous time for pensions, a change in tone towards greater unity and cross-department collaboration would be very welcome.

In order for everyone to acclimatise properly to the new normal, the new chancellor should commit to a return to a longer-term, strategic approach to pensions policymaking, enabling all parties, from regulators and providers to customers, to make decisions with confidence that the landscape will not continue to shift as fundamentally as it has in recent times.
