According to a report by the McKinsey Global Institute, global debt is now higher than before the financial crisis. And that crisis was largely caused by excessive lending. As The Telegraph article linked below states:
The figures are as remarkable as they are terrifying. Global debt – defined as the liabilities of governments, firms and households – has jumped by $57 trillion, or 17% of global GDP, since the fourth quarter of 2007, which was supposed to be the peak of the bad old credit-fuelled days. In 2000, total debt was worth 246% of global GDP; by 2007, this had risen to 269% of GDP and today we are at 286% of GDP.
This is not how policy since the financial crisis was supposed to have worked out. Central banks and governments have been trying to encourage greater saving and reduced credit as a percentage of 
GDP, a greater capital base for banks, and reduced government deficits as a means of reducing government debt. But of 47 large economies in the McKinsey study, only five have succeeded in reducing their debt/GDP ratios since 2007 and in many the ratio has got a lot higher. China, for example, has seen its debt to GDP ratio almost double – from 158% to 282%, although its government debt remains low relative to other major economies.
Part of the problem is that the lack of growth in many countries has made it hard for countries to reduce their public-sector deficits to levels that will allow the public-sector debt/GDP ratio to fall.
In terms of the UK, private-sector debt has been falling as a percentage of GDP. But this has been more than offset by a rise in the public-sector debt/GDP ratio. As Robert Peston says:
[UK indebtedness] increased by 30 percentage points, to 252% of GDP (excluding financial sector or City debts) – as government debts have jumped by 50 percentage points of GDP, while corporate and household debts have decreased by 12 and 8 percentage points of GDP respectively.
So what are the likely consequences of this growth in debt and what can be done about it? The articles and report consider these questions.

The first link below is to an excellent article by Noriel Roubini, Professor of Economics at New York University’s Stern School of Business. Roubini was one of the few economists to predict the 2008 financial crisis and subsequent recession. In this article he looks at the current problem of substantial deficiency of demand: in other words, where actual output is well below potential output (a negative output gap). It is no wonder, he argues, that in these circumstances central banks around the world are using unconventional monetary policies, such as virtually zero interest rates and quantitative easing (QE).
He analyses the causes of deficiency of demand, citing banks having to repair their balance sheets, governments seeking to reduce their deficits, attempts by firms to cut costs, effects of previous investment in commodity production and rising inequality.
The second link is to an article about the prediction by the eminent fund manager, Crispin Odey, that central banks are running out of options and that the problem of over-supply will lead to a global slump and a stock market crash that will be ‘remembered in a hundred years’. Odey, like Roubini, successfully predicted the 2008 financial crisis. Today he argues that the looming ‘down cycle will cause a great deal of damage, precisely because it will happen despite the efforts of central banks to thwart it.’
I’m sorry to post this pessimistic blog and you can find other forecasters who argue that QE by the ECB will be just what is needed to stimulate economic growth in the eurozone and allow it to follow the USA and the UK into recovery. That’s the trouble with economic forecasting. Forecasts can vary enormously depending on assumptions about variables, such as future policy measures, consumer and business confidence, and political events that themselves are extremely hard to predict.
Will central banks continue to deploy QE if the global economy does falter? Will governments heed the advice of the IMF and others to ease up on deficit reduction and engage in a substantial programme of infrastructure investment? Who knows?

Questions
- Explain each of the types of unconventional monetary policy identified by Roubini.
- How has a policy of deleveraging by banks affected the impact of quantitative easing on aggregate demand?
- Assume you predict that global economic growth will increase over the next two years. What reasons might you give for your prediction?
- Why have most commodity prices fallen in recent months? (In the second half of 2014, the IMF all-commodity price index fell by 28%.)
- What is likely to be the impact of falling commodity prices on global demand?
- Some neo-liberal economists had predicted that central bank policies ‘would lead to hyperinflation, the US dollar’s collapse, sky-high gold prices, and the eventual demise of fiat currencies at the hands of digital krypto-currency counterparts’. Why, according to Roubini, did the ‘root of their error lie in their confusion of cause and effect’?
In a speech in Dublin on 28 January 2015, titled ‘Fortune favours the bold‘, Mark Carney, the Governor of the Bank of England, compared the UK economy to that of the 19-nation eurozone. While he welcomed the ECB’s recently announced quantitative easing programme, he argued that the current construction of the eurozone is unfinished and still has two fundamental weaknesses that have not been addressed.
The first is the fragmented nature of banking:
With limited cross-border banking in the euro area, savings don’t flow to potential investments. Euro-area corporates’ cash balances have risen to the tune of €420 billion, or 3% of GDP, since the crisis, for example. Modest cross-border equity flows mean inadequate risk sharing.
The second is the lack of an integrated fiscal policy.
For complete solutions to both current and potential future problems, the sharing of fiscal risks is required.
It is no coincidence that effective currency unions tend to have centralised fiscal authorities whose spending is a sizeable share of GDP – averaging over a quarter of GDP for advanced countries outside the euro area.
… If the eurozone were a country, fiscal policy would be substantially more supportive. However, it is tighter than in the UK, even though Europe still lacks other effective risk sharing mechanisms
and is relatively inflexible. A more constructive fiscal policy would help recycle surplus private savings and mitigate the tail risk of stagnation. It would also bridge the drag from structural reforms on nominal spending and would be consistent with the longer term direction of travel towards greater integration.
But fiscal integration requires a political will to transfer fiscal surpluses from the stronger countries, such as Germany, to the weaker countries, such as those in southern Europe.
Overall, the financial and fiscal position in the eurozone is strong:
Gross general government debt in the euro area is roughly the same as in the UK and below the average of advanced economies. The weighted average yield on 10-year euro area sovereign debt is around 1%, compared to 1½% in the UK. And yet, the euro area’s fiscal deficit is half that in the UK. Its structural deficit, according to the IMF, is less than one third as large.
But, unlike the UK, where, despite the rhetoric of austerity, automatic fiscal stabilisers have been allowed to work and the government has accepted a much slower than planned reduction in the deficit, in the eurozone fiscal policy remains tight. Yet unemployment, at 11½%, is twice the rate in the UK and economic growth, at around 0.7% is only one-quarter of that in the UK.
Without a eurozone-wide fiscal policy the problem of slow growth is likely to persist for some time. Monetary policy in the form of QE will help and structural reforms will help to stimulate potential output and long-term growth, but these policies could be much more effective if backed up by fiscal policy.
Whether they will be any time soon is a political question.

After Syriza’s dramatic victory in the Greek election, it is now seeking to pursue its manifesto promises of renegotiating the terms of Greece’s bailout and bringing an end to austerity policies.
The bailout of €240bn largely involved debt restructuring to give Greeks more time to pay. A ‘haircut’ (reduction) on privately held bonds, estimated to be somewhere between €50bn and €110bn, was more than offset by an increase of €130bn in loans granted by official creditors.
The terms of the bailout negotiated with the ‘Troika’ of the EU Commission, the ECB and the IMF, had forced the previous Greek government to make substantial fiscal adjustments. These have included large-scale cuts in government expenditure (including public-sector wages), increases in taxes, charges and fares, and selling state assets through an extensive programme of privatisation.
Although Greece is now regarded as having achieved a structural budget surplus (a surplus when the economy is operating at potential output: i.e. with a zero output gap), 
the austerity policies and a decline in inward investment have dampened the economy so much that, until last year, the actual budget deficit and public-sector debt continued to rise as tax revenues plummeted.
Since 2007, GDP has fallen by nearly 27% and the unemployment rate is around 26%. The fall in GDP has made the achievement of a reduction in the debt/GDP ratio that much harder. General government debt has risen from 103% of GDP in 2007 to 176% in 2014, and the budget deficit, although having peaked at 12.2% of GDP in 2013, has only been brought down through huge cuts.
As a report to the European Parliament from the Economic Governance Support Unit argues on page 27:
With less front-loaded fiscal adjustment, the EU-IMF financing envelope for Greece would have needed to expand, in what is already the largest financial assistance programme in percent of GDP in recent global history. On the other hand, a less rapid fiscal adjustment may have helped to preserve some of the productive capacity that, in the course of the adjustment, was destroyed.
The new government, although pledging not to default on debt, is insistent on renegotiating the debt and wants to achieve a high level of rescheduling and debt forgiveness. As the new Prime Minister, Alexis Tsipras, says:
On existing loans, we demand repayment terms that do not cause recession and do not push the people to more despair and poverty. We are not asking for new loans; we cannot keep adding debt to the mountain.
But, just as the Greek government is insistent on renegotiating its debt, so the German government and others in the EU are insisting that Greece sticks to the terms of the bailout and carries on with its current programme of debt reduction. Another haircut, they maintain, is out of the question.
We must wait to see how the negotiations play out. We are in the realms of game theory with various possible threats and promises on either side. It will be interesting to how these threats and promises are deployed.

As we saw in Part 1 of this blog, oil prices have fallen by some 46% in the past five months. In that blog we looked at the implications for fuel prices. Here we look at the broader implications for the global economy? Is it good or bad news – or both?
First we’ll look at the oil-importing countries. To some extent the lower oil price is a reflection of weak global demand as many countries still struggle to recover from recession. If the lower price boosts demand, this may then cause the oil price to rise again. At first sight, this might seem merely to return the world economy to the position before the oil price started falling: a leftward shift in the demand for oil curve, followed by a rightward shift back to where it was. However, the boost to demand in the short term may act as a ‘pump primer’. 
The higher aggregate demand may result in a multiplier effect and cause a sustained increase in output, especially if it stimulates a rise in investment through rising confidence and the accelerator, and thereby increases capacity and hence potential GDP.
But the fall in the oil price is only partly the result of weak demand. It is mainly the result of increased supply as new sources of oil come on stream, and especially shale oil from the USA. Given that OPEC has stated that it will not cut its production, even if the crude price falls to $40 per barrel, the effect has been a shift in the oil supply curve to the right that will remain for some time.
So even if the leftward shift in demand is soon reversed so that there is then some rise in oil prices again, it is unlikely that prices will rise back to where they were. Perhaps, as the diagram illustrates, the price will rise to around $70 per barrel. It could be higher if world demand grows very rapidly, or if some sources of supply go off stream because at such prices they are unprofitable.
The effect on oil exporting countries has been negative. The most extreme case is Russia, where for each $10 fall in the price of oil, its growth rate falls by around 1.4 percentage points (see). Although the overall effect on global growth is still likely to be positive, the lower oil price could lead to a significant cut in investment in new oil wells. North sea producers are predicting a substantial cut in investment. Even shale oil producers in the USA, where the marginal cost of extracting oil from existing sources is only around $10 to £20 per barrel, need a price of around $70 or more to make investment in new sources profitable. What is more, typical shale wells have a life of only two or three years and so lack of investment would relatively quickly lead to shale oil production drying up.
The implication of this is that although there has been a rightward shift in the short-run supply curve, if price remains low the curve could shift back again, meaning that the long-run supply curve is much more elastic. This could push prices back up towards $100 if global demand continues to expand.
This can be illustrated in the diagram. The starting point is mid-2014. Global demand and supply are D1 and S1; price is $112 per barrel and output is Q1. Demand now shifts to the left and supply to the right to D2 and S2 respectively. Price falls to $60 per barrel and, given the bigger shift in supply than demand, output rises to Q2. At $60 per barrel, however, output of Q2 cannot be sustained. Thus at $60, long-run supply (shown by SL) is only Q4.
But assuming the global economy grows over the coming months, demand shifts to the right: say, to D3. Assume that it pushes price up to $100 per barrel. This gives a short-run output of Q3, but at that price it is likely that supply will be sustainable in the long run as it makes investment sufficiently profitable. Thus curve D3 intersects with both S2 and SL at this price and quantity.
The articles below look at the gainers and losers and at the longer-term effects.

According to a report by the McKinsey Global Institute, global debt is now higher than before the financial crisis. And that crisis was largely caused by excessive lending. As The Telegraph article linked below states:
GDP, a greater capital base for banks, and reduced government deficits as a means of reducing government debt. But of 47 large economies in the McKinsey study, only five have succeeded in reducing their debt/GDP ratios since 2007 and in many the ratio has got a lot higher. China, for example, has seen its debt to GDP ratio almost double – from 158% to 282%, although its government debt remains low relative to other major economies.
