Major Banks Still Hide $Trillions In The Shadows

After the so-called Wall Street reform and the new Basel II rules has been approved, one might think that we have some kind of framework in place that’ll give us more transparency into the global financial activity, and hopefully a possibility to put the brakes on if any of the major banks should try to run wild again. But that’s certainly not the case. A few major US and European banks still keep about USD 25 trillion – of their total interbank market of USD 55 trillion – in the shadow banking system – with no oversight, no rules and no control.

“The first change that is required is what I have called a true “quantum leap” in the rules that regulate how countries make their national economic policies.”

Jean-Claude Trichet

The shadow banking system or the shadow financial system consists of non-depository banks and other financial entities – investment banks, hedge funds, and money market funds – that grew dramatically in size after the year 2000 is still playing a critical role in lending between banks and  businesses. It is also a key element in explaining the financial crisis. But little has changed  over the last couple of years.

Shadow banking institutions are typically intermediaries between investors and borrowers. For example, an institutional investor like a pension fund may be willing to lend money, while a corporation may be searching for funds to borrow.

The shadow banking institution will channel funds from the investors to the corporation, profiting either from fees or from the difference in interest rates between what it pays the investors and what it receives from the borrower.

Many shadow-bank-like institutions and vehicles emerged in both the American and the European markets between 2000 and 2008, and have come to play an important role in providing credit across the global financial system.

In June 2008, US Treasury Secretary Timothy Geithner, then President and CEO of the NY Federal Reserve Bank, described the growing importance of the shadow banking system, saying:

“In early 2007, asset-backed commercial paper conduits, in structured investment vehicles, in auction-rate preferred securities, tender option bonds and variable rate demand notes, had a combined asset size of roughly $2.2 trillion. Assets financed overnight in triparty repo grew to $2.5 trillion. Assets held in hedge funds grew to roughly $1.8 trillion. The combined balance sheets of the then five major investment banks totaled $4 trillion. In comparison, the total assets of the top five bank holding companies in the United States at that point were just over $6 trillion, and total assets of the entire banking system were about $10 trillion.”


In other words, lending through the shadow banking system seemed to exceed lending via the traditional banking system based on outstanding balances.

The equivalent of a bank run occurred within the shadow banking system during 2007 – 2008, when investors stopped providing funds to (or through) many entities in the system. Disruption in the shadow banking system is a key component of the ongoing financial crisis that started with the  US subprime mortgage crisis.

But in spite of all the new regulations, both legislated and proposed, the shadow banking market seems to keep on growing.

According to the latest estimates from the IMF (illustrated above) the shadow interbank market of the major US and European banks is estimated to about USD 25 trillion, compared to the “official” banking system with an estimated value of USD 30 trillion.

I assume there’s no (or little) data on the Chinese shadow banking market. And if you take all banks in the world into account, you’ll end up with a global financial shadow system of stunningly USD 450 trillion!

Now – compare this to the total value of the global economy.
.
Or – to the total size of the US economy.

(NOTE: This is the notional value rather than market value, but in uncertain times market values and notional values can converge.)

.

In short, it’s the massive pile of derivatives accumulated over the past decades.

It’s also tightly coupled and extremely complex, and worse, not fully understood.

It isn’t regulated, nor is it liquid enough to price, which is why global banks are still able to “act” like they are solvent.

You can also view the shadow banking system is as a financial amplification system.
A byproduct of its operation is that it can take small financial events and convert them into financial nuclear weapons that explode with a spectacular display and devastating effect.
I would not be surprised if we were to see more financial nuclear explosions as the shadow banking system may amplify an increasing number of small and unexpected events into a full-blown disasters.

Trichet’s Desperate Call

“The first change that is required is what I have called a true “quantum leap” in the rules that regulate how countries make their national economic policies. Countries need clear rules and procedures to guide policy-making and sanctions if they stray from a sustainable path,” Jean-Claude Trichet said in a speech on February 11.

Trichet pointed out that this means a strengthening of the European Stability and Growth Pact, (the framework first negotiated by the German finance minister Theo Waigel to prevent countries accumulating excessive public debts and deficits).

“The period between 1999 and 2008 was generally acknowledged as a period of economic fair weather. Yet in this period, hardly any euro area country put their fiscal house in order, attaining what might be called a safe budgetary position. What is more, governments decided to weaken the Pact in 2004 and 2005. This initiative was led by the euro area’s largest economies.”

“The ECB voiced its grave concerns at the time. I now see that many acknowledge that the weakening of the Pact was a serious misjudgment.”

“But the crisis has given us an opportunity. It has made plain the flaws in the Pact that allowed countries’ fiscal policies to become a problem, not just for themselves, but for everyone else within the monetary union. We now have an obligation to fix the flaws.”

First and foremost, this means creating stronger and more binding rules for fiscal policy, backed up by reinforced sanctions or mechanisms to ensure compliance with the rules, Trichet said.

Second, a new framework is needed to monitor competitiveness and to ensure that measures are taken to control them.

“We need to put in place binding rules that guide policies towards sustainable and balanced growth. Such a reform package is currently before the European Parliament. The ECB very much counts on the Parliament to call for very clear and strong governance rules, including automatically in triggering procedures and sanctions, which will be to the long-term benefit of Europe’s citizens. In a union with a single monetary policy and 17 different fiscal and economic policies, a “quantum leap” in economic governance is necessary to ensure that the degree of economic union is fully commensurate to the already achieved monetary union.”

(Here’s a transcript of the speech.)

Exactly How Serious?

“Grave concerns,” a “serious misjudgment,”  and need for a “quantum leap” in surveillance and regulation of the banking systemsounds pretty serious to me….

But finding out exactly how serious, is not an easy task.

However, the International Monetary Fund, IMF, have done some research on the topic. Recent published documents and working papers contains some statements, calculations and illustrations that gives some clarity of the problem.

In a working paper on cross-border capital flows from November 2010, the IMF researchers write:

“Thus, with international asset positions now dwarfing output, global portfolio allocations and reallocations have profound effects on the world economy, as demonstrated by recent boom-bust episodes of both global reach  and regional significance (in Asia, Latin America, and Central and Eastern Europe). Such cycles and reversals in cross-border capital flows should not be surprising, given that these flows—more so than domestic ones—imply crossing informational barriers, currency and macroeconomic risks, and regulatory regimes.”


“In contrast to trade in goods and services, there are no widely accepted “rules of the game” for international capital flows—this despite being the principal conduit for the transmission of global shocks.”


“Cross-border capital flows take place without global “rules of the game.” At the Fund [IMF], and in contrast to the obligation to liberalize payments and transfers for current international transactions, the Articles of Agreement explicitly grant members the right to “exercise such controls as are necessary to regulate international capital movements.” Since the failure to amend this provision of the Articles in 1997, the Fund’s work in this area has focused on analytical and conceptual issues, with policy advice not always offered consistently.”


While the consensus amongst professional economist seems to be that the cross-border activity mostly have positive effects on economic growth and financial stability, there is a few studies that points at the following:

  • There is no consensus on the appropriate speed of liberalization. Overly hasty loosening appears to have contributed to financial instability in a number of cases. While gradualism allows agents to adjust, interest groups may use delays to try to frustrate reform.
  • Weak regulation, especially of banks, is associated with financial crises following liberalization and suggests a more measured pace of liberalization, with regulatory reform running in parallel. Specific risk exposures of financial institutions should also be considered.
  • Weaknesses in fiscal or external conditions, or questions on debt sustainability, could result in premature capital account liberalization resulting in a rapid build-up in imbalances or an increase in vulnerability to large reversals in capital flows.

At a systemic level, the size and nature of cross-border financial liabilities between major financial centers implied that unprecedented international coordination is required to mobilize resources sufficient enough to stem the impact of the liquidity shock.

“Given that usage of the US Federal Reserve swap lines rose to US$600 billion during the crisis, it is pertinent to ask how future crises might be tackled should capital flows, and the attendant balance sheet exposures, resume their former growth trends,” the IMF researchers writes.

They also give a few hints on the current trends:

“Strong, structural, economic reasons underpin much cross-border investment: ageing populations in advanced economies, sustained differential in growth potential between emerging markets and advanced economies, steadily improving access to information and declining home bias in investment all suggest capital flows will keep increasing, albeit not necessarily in a steady fashion.”


“The global nature of capital flow cycles suggests that cross-border flows may be driven by common factors such as global liquidity conditions or overall increases in risk appetite.”


“Financial institutions will typically not consider the systemic vulnerabilities their actions engender, and single-country regulation can simply push financial activity elsewhere, without reducing systemic risk. Within economic cycles, banks may generate an externality by taking on too much risk as asset prices rise and the economy expands, without taking into account the consequences to the broader economy when the cycle turns down. This implies small shifts in assets within the institution can generate large capital flows for the debtor countries, and that neither the financial institution nor their home regulators will attach much weight to risks taken in these economies.”


Liberalization, maintenance, or re-imposition of capital controls has responded to domestic policy priorities, and has had often far-reaching consequences for domestic stability.

These policies have also had implications for partners, peer countries and, collectively, the IMS as a whole. Over the past decades, there has been a trend toward capital account liberalization.

Still out of control.

“This trend has declined in recent years, with emerging markets tightening controls on inflows at the margin, although this has not yet made an appreciable difference overall. More generally, for many emerging markets the process of integration with international capital markets has been “stop and go”, with periods of liberalization and growing capital inflows punctuated by reversals, and a less linear approach to liberalization, with some reversals in policy and a more frequent use of capital controls or prudential policies with a similar ultimate effect. The liberalization process has also varied across types of financial instruments, with a larger share of countries maintaining controls on debt creating capital inflows.”


And this is where the money seems to be heading:

Trends in capital flows.

The common roots and potential solutions for risks associated with capital flows arise in the context of an absence of any universal frameworks for addressing them, according to IMF.

In contrast to trade and related payments, for example, there is no universal framework that governs or otherwise oversees international capital movements. In turn, this might lead to the following:

Prolonged maintenance of controls: Could effectively protect the financial sector from competition, and act as a tool of financial repression. Long-run efficiency costs could be high. This idea lies behind the intellectual and policy trend toward liberalization.

Poorly sequenced or “too rapid” liberalization: Financial stability can be compromised by rapid liberalization in contexts of weak supervision or regulation, or unbalanced macroeconomic conditions. Some examples of crises where liberalization and its consequences played a role could include Chile in the early 1980’s and the Nordic crisis of the early 1990’s. Liberalization in accordance with EU accession requirements contributed to several emerging economies in Europe experiencing strong inflows and subsequent reversals in recent years.

Crisis controls: Once such a crisis arrives, controls on capital outflows may be necessary in circumstances where the potential level of outflows exceeds both the member’s adjustment capacity
and the financing available from the official sector.

Externalities from controls: To the extent capital flows to emerging markets are determined by “push factors”, their overall magnitude may be relatively invariant to conditions in individual markets. Imposition of capital controls may simply displace flows to other economies with similar attributes. Policymakers have raised this concern in recent weeks, though it may be difficult to show empirically.

How much is $10 trillion?

Imagine a pile of $100 bills. (US banknotes are about 1/10 millimetres thick):

$10,000,000,000,000 / 100 = 100 billion x $100 banknotes
/10 = 10 billion millimetres
/1000 = 10 million metres
/1000 = 10,000 km (+/- 6,200 miles)

Can you imagine a pile of $100 bills 6.200 miles high – or, if laid flat – stretching all the way from Los Angeles across the USA, over the Atlantic, through Europe, and on to 100 miles past Moscow?

(And 450 trillion?!…)

Mama Mia!

Hey, You HFT Bashers! Are You Ready For This?

The quantum computer has been underway for 20 years now. But scientist  are still not sure how to use them in real life, or for what. However, they’ve just made another amazing discovery;  the quantum computer will be  able to run – even with faulty programming and missing components.

“We have no idea what these systems could be used for in the future.”

Sean Barrett

Well, I see one obvious possibility – online trading in the financial markets. With one quantum processor placed at the trading desk and the equivalent processor placed at the market, the latency (delay) in transmission of orders will be completely eliminated. Even if the trading desk is several thousand light-years away, orders can be executed instantly. The limitations by the speed of light will be history.

If you think this is some kind of science fiction, or something that belongs to a distant future, you better update you knowledge on computer technology.

The 5 qubits quantum processor, presented by IBM in 2000.

In fact, the first quantum computer was up and running already in 2000 – 10 years ago.

For every month that passes, we get another step closer to manage this advanced and strange technology.

And now it seems like it will a lot easier the scientists previously have thought.

According to a study published in Physical Review Letters the quantum computers will still be able to work, even with a large number of faulty or even missing components.

This surprising discovery brings scientists one step closer to designing and building real-life quantum computing systems — devices that could have enormous potential across a wide range of fields, from drug design, electronics, and even code-breaking, DailyScience.com reports.

In Two Places At The Same Time

Scientists have long been fascinated with building computers that work at a quantum level — so small that the parts are made of just single atoms or electrons.

Instead of “bits”, the building blocks normally used to store electronic information, quantum systems use quantum bits or “qubits“, made up of an arrangement of entangled atoms.

Materials behave very differently at this tiny scale compared to what we are used to in our everyday lives — quantum particles, for example, can exist in two places at the same time.

Qubits in action

“Quantum computers can exploit this weirdness to perform powerful calculations, and in theory, they could be designed to break public key encryption or simulate complex systems much faster than conventional computers,” says Dr. Sean Barrett, the lead author of the study, who is a Royal Society University Research Fellow in the Department of Physics at Imperial College London.

The machines have been notoriously hard to build, however, and were thought to be very fragile to errors.

In spite of considerable buzz in the field in the last 20 years, useful quantum computers remain elusive.

But Dr. Barrett and his colleague Dr. Thomas Stace, from the University of Queensland in Brisbane, Australia, have now found a way to correct for a particular sort of error, in which the qubits are lost from the computer altogether.

Correct Itself

They used a system of  “error-correcting” code, which involved looking at the context provided by the remaining qubits to decipher the missing information correctly.

Dr. Sean Barret explains:

“Just as you can often tell what a word says when there are a few missing letters, or you can get the gist of a conversation on a badly connected phone line, we used this idea in our design for a quantum computer.”

They discovered that the computers have a much higher threshold for error than previously thought — up to a quarter of the qubits can be lost — but the computer can still be made to work.

“It’s surprising, because you wouldn’t expect that if you lost a quarter of the beads from an abacus that it would still be useful,” Barret adds.

The findings indicate that quantum computers may be much easier to build than previously thought, but as the results are still based on theoretical calculations, the next step is to actually demonstrate these ideas in the lab.

Scientists will need to devise a way for scaling the computers to a sufficiently large number of qubits to be viable.

At the moment the biggest quantum computers scientists have built are limited to just two or three qubits.

“We are still some way off from knowing what the true potential of a quantum computer might be,” Barrett notes.

“At the moment quantum computers are good at particular tasks, but we have no idea what these systems could be used for in the future,” he says.

“They may not necessarily be better for everything, but we just don’t know. They may be better for very specific things that we find impossible now.”

What will happen if you use human DNA as input data for a quantum computer?

HFT To The People

The controversial high frequency trading, that now makes up about 70 percent of the total trading volume in the US stock market, belongs to a small exclusive club of financial firms. At the moment, that is.

However, that’s all about to change.

According to the Quantiki.org, the computer speed doubles every 18th month.

The first programmable quantum computer, released by Intel, November 2009.

Leading the race right now is Intel Corp. with its new series of Intel Core processors. The fastest so far, the 10 gigabits per second Light Peak connector, is able to communicate almost at the speed of light.

But according to the magazine PC Pro, Intel have already made the breakthrough in developing a 50 gigabits per second processor, using laser and fiber optical techniques.

The transmitter chip is composed of four hybrid silicon lasers, which fire into an optical modulator that encodes data at up to 12,5 gigabits per second.

At the other end of the link, the receiver chip separates the four optical beams and directs them into photo detectors, that in turn convert the data back into electronic signals.

According to PC Pro, the 10 Gb/sec Peak Light processor is set to arrive at the commercial markets in 2011. The 50Gb/sec is about three to five years away.

Then, even your grandma can be a high frequency trader…

Affordable For Anyone (Almost)

And the HFT industry itself are very keen on getting the race-trading out to the common investors and private day traders.

In fact, “Practical Implementation of High-Frequency Trading Strategies” is the title of a workshop for leaders of HFT firms, November 22 and 23 in Hong Kong and December 9 and 10 in New York.

Peter Van Kleef

In an interview with the FX Trader Magazine recently,  Chief Executive Officer of Lakeview Arbitrage, Peter van Kleef, points out that it doesn’t take much to get into high frequency trading these days:

“These days you can get a brokerage account that gives you an API you can connect to with a minimum deposit of around 2K USD and you can download an open source engine like Marketcetera for free to get you started. Of course there are serious limitations to what you can do with such a low-cost setup but it can get you started on a platform that can grow with your skills and needs. Going forward, you will see university students and even people from high school starting in algo trading from home. Even if you want a state of the art setup, it doesn’t need to break the bank. HFT trading has become affordable for almost anyone.”

About the evolution of HFT on the institutional side, Mr. van Kleef says; “many institutional investors have a fairly long-term horizon and it will take them a long time to understand that some high frequency techniques can benefit them greatly. At the moment many consider it a fad that will pass and therefore don’t engage in the topic. That’s a mistake but then again, the markets are usually a means for wealth transfer from many to a few and not the other way round.”

Do You See The Light?

The history of computer technology has involved a sequence of changes from one type of physical realisation to another – from gears to relays to valves to transistors to integrated circuits and so on.

As illustrated at the top of the page, the computer speed is now doubling every 18th month.

Can you handle the truth?

Today’s advanced lithographic techniques can create chips with features only a fraction of micron wide. But soon they will yield even smaller parts and inevitably reach a point where logic gates are so small that they are made out of only a handful of atoms.

On the atomic scale matter obeys the rules of quantum mechanics, which are quite different from the classical rules that determine the properties of conventional logic gates.

So if computers are to become smaller in the future, new, quantum technology must replace or supplement what we have now.

The point is, however, that quantum technology can offer much more than cramming more and more bits to silicon, multiplying the clock, speed of microprocessors and make electronic trading many times faster than today’s high frequency systems.

It can support entirely new kind of computation with qualitatively new algorithms based on quantum principles.

It also means (among several other things) the possibility to be in two places at the same time. A realization on the “earth is round – not flat”-level.

Now, take a minute to think about this…
