Why so much is read into the words of the Fed chairman.

Following Fed chairman Ben Bernanke's speech yesterday, the usual bout of trying to understand quite how much we can read in to his words has begun. Yet unlike the normally perjorative "Kremlinology" – attempting to infer things from the most minuscule turns of phrase – this Bernankeology is understandable and quite useful.

Central bankers have a strange job. They don't actually have many tools at their disposal; largely just the tripartite decision to raise, lower, or maintain interest rates. Yet many of the outcomes they create come, not from actually using this power, but from creating expectations as to their future use.

Suppose Bernanke knows he is likely to raise interest rates in the first quarter of 2013. Even though his actual power is relatively limited, he can create a wide spectrum of outcomes depending on how he announces this. The market reaction will be extremely different if Bernanke says now that he will raise rates in a years time, compared to if he maintains right up until the day that a rate rise would be inappropriate.

But this power to persuade brings with it its own problems. Just like a legislature, a central bank is fundamentally unable to constrain itself; it can make promises, but everyone knows that it is free to break them at any point.

All of this means that every speech Bernanke gives is likely to be very carefully aimed at creating just the right set of expectations. On the one hand, he can't ever gain a reputation for untrustworthiness, so they have to be scrupulously honest; on the other, actually saying what he believes may create the wrong impression.

Last week, Ryan Avent provided a detailed breakdown of exactly what the benefits of Bernankeology can be, focusing on the Fed's "forward guidance" where it hinted that it would keep interest rates low until at least 2013. He writes:

On the one hand, a pure focus on the language of the Fed's statement indicates that rates are likely to remain low through that period based on the state of the economy... On the other hand, the Fed may be hinting that it will be willing to keep rates low through late 2014 even if the trajectory of the economy warrants a rate increase.

In other words, the Fed might be attempting to commit itself to a deviation from its normal policy rules of the sort that might generate more rapid growth and inflation.

The problem the Fed has is that it needs to generate growth, but that growth is likely to come with relatively high inflation, of the sort which Bernanke has historically fought against. In order to help the economy, he needs to convince "the markets" that interest rates will be kept low even if inflation spirals out of control. The problem is that this, from an inflationary hawk like Bernanke, is unbelievable.

Avent points to a paper (pdf) which breaks down the distinction into two categories:

Delphic, corresponding to the first category above, and Odyssean, corresponding to the second, in which the central bank attempts to commit itself to deviations from typical rules.

Matt Yglesias offers a less refined version of the same strategy, breaking Bernanke's possible responses into an Eeyore response and a Tigger one. Either the Fed chief can "avoid optimistic forecasts as a way of signaling that rates will stay low for a long time," or he "can say we're climbing out of a steep hole so rates will stay low for the next 18 months come what may".

The test for Bernankeologists is to work out whether yesterday's gloomy speech is Odyssean-Eeyore, using gloominess as a mast to bind himself to, or simply Delphic, with the chairman making his most honest predictions and still being pessimistic.

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.
