Eurozone soap opera reveals a damaged relationship with markets

Democracies need to get some self-respect.

We’re all familiar with the story. Girl meets glamorous guy with flashy car and nice teeth who promises her the world. He screws around, and when she gets angry, he threatens to leave. But by now our girl is so dependent on the guy she’s desperate for him to stay. Sobbing, she throws herself at his feet and promises she’ll do better.

This soap opera can help us understand what’s playing out in the eurozone.

States fell in love with markets, and they let us down. Financial deals we depended on turned out to be phonies. When we talk about introducing extra regulation to prevent this happening again, financial institutions threaten to leave our borders and seek pleasure elsewhere.

Like the girl, democracies are now the ones offering to change. At the centre of the emerging eurozone plan is a call for fiscal integration, whereby states promise to abide by strict spending limits in return for bailout funds. But the underlying causes of under-regulation and overconcentration of market power remain unsolved. Our relationship with the City still suffers from an imbalance of power and we’re still at risk.

We need to be more honest about what triggered the current European crisis. Apart from Greece, the problem was not unsustainable levels of public spending. It was banks handing out risky loans and stockpiling bad debts. Spain is a classic example. The country ran a balanced budget until 2008, when it was forced to pile horrific property debts onto the public balance sheet to bail out irresponsible lenders. As this fantastic BBC graph shows  (see total debt graph), this is a common pattern for most countries.

I don’t want to abdicate responsibility. We all took on those loans from the banks when we shouldn’t. We all enjoyed that party in a bubble and lived a false dream when we should have kept a tighter eye on reality. Britain should have been in surplus from 2004-2008. The girl in our story should have been brave enough to see the writing on the wall. We should have taken action earlier.

But we are where we are. All we can do is change our behaviour now. It’s understandable that Merkel wants fiscal rules on states to make sure they don’t blow German money. But without addressing the banks too, you’re setting up a terrible incentive problem. Everyone knows if the girl gets back with the guy without punishing him for cheating, he’s going to do it again. In fact now he knows he can get away with it, he’s more likely to.

Sadly in the middle of the crisis, no country feels strong enough to limit financial services, whether it improves stability or not. In a desperate attempt to grow, governments are happy for banks to throw money at anything. Any bubble is better than stagnation. We don’t have the self-esteem or self-confidence to challenge our irresponsible partner and build a better relationship.

Although there is some talk of banking union, this is more about sharing bad debts than introducing stronger lending conditions. Although some like former F&C chairman Robert Jenkins says this may change, at the moment the assumption that “liquidity is free and will and will be freely available” continues to hold.

Britain is one of the greatest sufferers of self-delusion. Osborne is massively opposed to the transaction tax – the one small move Europe might be prepared to take to challenge the City – and he used his recent Mansion House speech to announce that the state will be underwriting risky loans. He’s pulled back on the already watered down proposals of the Vickers Commission, reducing the required amount of back up deposits to three per cent when columnists like Martin Wolf at the FT are calling for ten per cent.

You don’t have to be an agony aunt to figure out what comes next. Without a change in this poisonous relationship, we’re setting ourselves up for another fall. Our girl needs to rediscover her self-respect. Get it wrong, and it will hurt. But get it right, and democracies and markets have a chance to build a new, more honest and productive future together.

Inside Big Ben: why the world’s most famous clock will soon lose its bong

Every now and then, even the most famous of clocks need a bit of care.

London is soon going to lose one of its most familiar sounds when the world-famous Big Ben falls silent for repairs. The “bonging” chimes that have marked the passing of time for Londoners since 1859 will fall silent for months beginning in 2017 as part of a three-year £29m conservation project.

Of course, “Big Ben” is the nickname of the Great Bell and the bell itself is not in bad shape – even though it does have a huge crack in it.

The bell weighs nearly 14 tonnes and it cracked in 1859 when it was first bonged with a hammer that was way too heavy.

The crack was never repaired. Instead the bell was rotated one eighth of a turn and a lighter (200kg) hammer was installed. The cracked bell has a characteristic sound which we have all grown to love.

Big Ben strikes. UK Parliament.

Instead, it is the Elizabeth Tower (1859) and the clock mechanism (1854), designed by Denison and Airy, that need attention.

Any building or machine needs regular maintenance – we paint our doors and windows when they need it and we repair or replace our cars quite routinely. It is convenient to choose a day when we’re out of the house to paint the doors, or when we don’t need the car to repair the brakes. But a clock just doesn’t stop – especially not a clock as iconic as the Great Clock at the Palace of Westminster.

Repairs to the tower are long overdue. There is corrosion damage to the cast iron roof and to the belfry structure which keeps the bells in place. There is water damage to the masonry and condensation problems will be addressed, too. There are plumbing and electrical works to be done for a lift to be installed in one of the ventilation shafts, toilet facilities and the fitting of low-energy lighting.

Marvel of engineering

The clock mechanism itself is remarkable. In its 162-year history it has only had one major breakdown. In 1976 the speed regulator for the chimes broke and the mechanism sped up to destruction. The resulting damage took months to repair.

The weights that drive the clock are, like the bells and hammers, unimaginably huge. The “drive train” that keeps the pendulum swinging and that turns the hands is driven by a weight of about 100kg. Two other weights that ring the bells are each over a tonne. If any of these weights falls out of control (as in the 1976 incident), they could do a lot of damage.

The pendulum suspension spring is especially critical because it holds up the huge pendulum bob which weighs 321kg. The swinging pendulum releases the “escapement” every two seconds which then turns the hands on the clock’s four faces. If you look very closely, you will see that the minute hand doesn’t move smoothly but it sits still most of the time, only moving on each tick by 1.5cm.

The pendulum swings back and forth 21,600 times a day. That’s nearly 8m times a year, bending the pendulum spring. Like any metal, it has the potential to suffer from fatigue. The pendulum needs to be lifted out of the clock so that the spring can be closely inspected.

The clock derives its remarkable accuracy in part from the temperature compensation which is built into the construction of the pendulum. This was yet another of John Harrison’s genius ideas (you probably know him from longitude fame). He came up with the solution of using metals of differing temperature expansion coefficient so that the pendulum doesn’t change in length as the temperature changes with the seasons.

In the Westminster clock, the pendulum shaft is made of concentric tubes of steel and zinc. A similar construction is described for the clock in Trinity College Cambridge and near perfect temperature compensation can be achieved. But zinc is a ductile metal and the tube deforms with time under the heavy load of the 321kg pendulum bob. This “creeping” will cause the temperature compensation to jam up and become less effective.

So stopping the clock will also be a good opportunity to dismantle the pendulum completely and to check that the zinc tube is sliding freely. This in itself is a few days' work.

What makes it tick

But the truly clever bit of this clock is the escapement. All clocks have one - it’s what makes the clock tick, quite literally. Denison developed his new gravity escapement especially for the Westminster clock. It decouples the driving force of the falling weight from the periodic force that maintains the motion of the pendulum. To this day, the best tower clocks in England use the gravity escapement leading to remarkable accuracy – better even than that of your quartz crystal wrist watch.

In Denison’s gravity escapement, the “tick” is the impact of the “legs” of the escapement colliding with hardened steel seats. Each collision causes microscopic damage which, accumulated over millions of collisions per year, causes wear and tear affecting the accuracy of the clock. It is impossible to inspect the escapement without stopping the clock. Part of the maintenance proposed during this stoppage is a thorough overhaul of the escapement and the other workings of the clock.

The Westminster clock is a remarkable icon for London and for England. For more than 150 years it has reminded us of each hour, tirelessly. That’s what I love about clocks – they seem to carry on without a fuss. But every now and then even the most famous of clocks need a bit of care. After this period of pampering, “Big Ben” ought to be set for another 100 or so years of trouble-free running.
