Eyes on Xi-Trump talks; US data suggests stagflation; California declares El Niño emergency; Canada sees growth halving; copper in new push higher; UST 10yr at 4.96%; gold and oil ease; NZ$1 = 57.2 USc; TWI-5 = 60.7

One of the best journalistic questions to ask, is: Why? 

And the answer isn't: Trump. 

Here's a journo who asked the question:

Radical Simplicity: The Opportunities of a World in Collapse - The Great Simplification

DO THE DAILY NUMBERS HIDE THE BIGGER STORY?

I increasingly wonder whether the way we report sovereign bond markets is obscuring the far more important story developing underneath them.

Take the daily bond snapshot this morning. The US 10-year is down 4 basis points, the 30-year down 2, China down 4, Japan unchanged, Australia unchanged and New Zealand up one - read that in isolation and everything sounds remarkably normal.

But is that really the appropriate lens through which to view what is happening - the US 10-year is still sitting around 4.96% and the 30-year around 5.31%. Meanwhile, serious stresses have been appearing elsewhere across the developed sovereign complex - long UK gilt yields have been under considerable pressure - German Bund yields have moved to levels not seen for many years - France is dealing with deteriorating fiscal arithmetic and widening spreads over Germany, and Italy continues carrying an enormous public-debt burden.

None of that proves that a systemic sovereign-debt crisis is imminent. But neither does yesterday's 4-basis-point fall in the Treasury yield tell us very much about the structural health of the system.

I believe that conventional reporting increasingly misses the forest for the trees - IOWs the structural health of the system - surely a very real question is what size of productive economic base ultimately stands underneath the mountain of financial claims being accumulated above it?

THE DENOMINATOR PROBLEM

This is where my use of Productive GDP, or PGDP, differs fundamentally from conventional GDP. Headline GDP counts enormous quantities of economic activity generated within an increasingly financialised economy. Financial intermediation, property-related activity, government expenditure, various professional services and other components all contribute to measured GDP.

That is perfectly legitimate according to national-accounting conventions. But it doesn't necessarily follow that every dollar counted equally represents productive capacity capable of supporting an ever-expanding stock of debt.

A PGDP framework attempts to strip the problem back to something much more fundamental - how much genuinely productive output does an economy generate from which its accumulated financial claims can ultimately be serviced?

WHEN GDP BECOMES THE ILLUSION

That distinction becomes increasingly important as an economy financialises. Imagine an economy in which debt, asset prices, financial turnover and government expenditure all grow rapidly. 

Measured GDP can continue expanding because much of the activity surrounding those financial claims is itself incorporated into GDP. The financial superstructure can therefore become larger while simultaneously making the statistical economy appear larger.

But the underlying productive economy may not be expanding remotely as quickly - and therein lies the potential illusion. We continually quote debt-to-GDP ratios as though the denominator was automatically an appropriate measure of the economic capacity supporting the numerator.

Its not when the composition of GDP is progressively shifting away from productive wealth creation and towards activity generated by financialisation, asset inflation, government deficits and servicing the financial architecture itself, then headline GDP can substantially disguise deterioration in the relationship that really matters - productive capacity relative to accumulated financial claims.

This is why I find the contrast between the US and China particularly interesting.

China's 10-year government bond is around 1.68%, while the US 10-year is approaching 5%. Whatever one's views about either political or economic system, that enormous difference deserves considerably more examination than it usually receives.

PGDP estimates suggest that China's genuinely productive economy represents a much larger proportion of its headline economy than America's does. Conversely, a very large component of American GDP now sits inside consumption, finance, property, healthcare administration, government expenditure and other service activity rather than the industrial and productive base from which external obligations ultimately have to be met.

That doesn't mean those services have no economic value. Obviously many do - it means that $1 of headline GDP is not necessarily equivalent to $1 of productive debt-servicing capacity.

Once that distinction is recognised, some apparently comfortable debt-to-GDP ratios begin looking considerably less so, and the problem becomes alarmingly self-reinforcing when bond yields rise.

WHO BUYS THE NEXT TRILLION?

A sovereign refinancing enormous quantities of debt at 5% faces a very different arithmetic from one refinancing at 2%. Higher interest expenditure increases fiscal deficits - larger deficits require additional issuance - additional issuance must find marginal buyers - and increasingly price-sensitive buyers may demand still higher yields to absorb that supply.

That is why today's marginal Treasury buyer is so vital - the important question isn't merely whether the latest auction was "covered". At some price almost anything can find a buyer. The question is what yield is increasingly required to induce that buyer to absorb the next trillion dollars of issuance?

And this isn't some obscure heterodox concern anymore - even dah IMF itself has been warning about the interaction between high sovereign indebtedness, refinancing requirements, increasingly price-sensitive investors, leveraged non-bank financial institutions, liquidity stresses and forced selling.

Those are precisely the mechanisms through which something that initially looks manageable can become a systemic shambles.

Britain has already provided an excellent demonstration of the underlying plumbing. The Bank of England's decision to stop actively selling long-dated gilts through its QT program doesn't mean Britain is insolvent, but it does tell us that the long end of the sovereign curve matters enormously when leverage, and pension-system structures are sitting on top of it.

France, Italy and Germany deserve watching for different reasons, as does Japan.

Perhaps the most sobering aspect is just how widespread this problem is becoming. Look across the world's largest advanced economies and variations of the same sovereign-bond challenge keep appearing — the United States, Japan, Germany, Britain, France, Italy and Canada all have to compete for increasingly price-sensitive capital, while governments continue issuing enormous quantities of debt and central banks are no longer the enormous price-insensitive marginal buyers they became during the QE era.

The circumstances obviously differ enormously from country to country, but the underlying question is remarkably similar: who buys the next bond, and at what yield? The IMF itself now warns that sovereign yields have become increasingly sensitive on auction days even though conventional measures such as bid-to-cover ratios can continue looking perfectly respectable. In other words, the bonds are still finding buyers — but increasingly at the price demanded by the buyer rather than the price preferred by the sovereign.

Japan makes this even more interesting because rising JGB yields are beginning to make domestic bonds more attractive to Japanese investors, potentially reducing one of the world's historically important sources of demand for foreign sovereign debt. That illustrates why this cannot sensibly be analysed as a collection of isolated national bond markets. The marginal buyer disappearing from one market may simply be a marginal buyer who has found a better price somewhere else.

When so many of the world's largest sovereign borrowers are competing simultaneously for that increasingly price-sensitive pool of capital, surely the relevant story is no longer whether one country's 10-year yield happened to fall four basis points overnight. It is the growing competition for the marginal buyer across the entire global sovereign-debt complex.

And then sitting at the centre of the system is the United States, simultaneously carrying enormous federal debt, persistent fiscal deficits and a deeply negative net international investment position while remaining responsible for supplying much of the reserve asset upon which the existing international monetary architecture depends.

THE STRUCTURAL LOAD

Surely serious financial analysis should at least be examining the structural load - and to me, that is ultimately why I think PGDP matters. GDP tells us the measured monetary value of economic activity occurring inside an economy. PGDP asks a very different question - how much real productive capacity exists underneath the financial claims?

As global debt continues expanding, sovereign refinancing costs rise and Western economies become progressively more financialised, I suspect that distinction is going to become considerably more important, because ultimately debt isn't serviced by GDP statistics.

It is serviced by income generated from an economy capable of producing sufficient real goods, services, exports, tax revenues and savings to honour the claims written against it.

If the financial claims continue growing much faster than that underlying productive base, a 4-basis-point daily decline in the bond yield isn't necessarily good news - it may simply be noise obscuring the a very sobering trend.
