ECB's money printing may stymie cash generators

LONDON (Reuters) - The European Central Bank may well be printing money via its landmark government bond buying program, but it could also be destroying some of the financial system's own printing presses in the process.

Little over a week after the ECB launched its 1 trillion euro 'quantitative easing' campaign, financial markets are fretting that there is a shortage of bonds for the central bank to buy.

This has created a hiatus in the plumbing of the global financial system that's seen bond yields and long-term interest rates vanish across the spectrum and move deeply negative in some cases, especially benchmark German bunds.

ECB officials insist this 'scarcity', rather than shortage, is a deliberate part of QE and forces down yields on the lowest risk bonds in order to push banks and investors into riskier lending more useful to the economy.

But the stimulus to cash flows around financial markets rather through the high streets has been far more seismic.

"ECB QE will not have a significant effect, at least in our view, on the real economy - but it is having a massive effect on financial markets," said Phil Poole, head of Research at Deutsche Asset & Wealth Management.

"There is clearly a distortion in the market which is leading investors generally to take more risk or buy less liquid assets in order to generate a return."

Some experts beg to differ with the ECB and say a growing shortage of top-rated bonds, particularly AAA-rated German bunds, is playing havoc with the way the financial system generates money within itself by the pledging and re-pledging of top quality bonds as collateral in return for cash.

Any shrinkage of this securities lending market, a giant moneyspinner with 5.5 trillion euros outstanding in Europe alone, has been a concern ever since the global credit crisis and subsequent regulation cut the range of bonds and counterparties involved, and limited the amount of times bonds are typically repledged for cash.

For example, a drop in the re-use rate of collateral in this way from about 3 times to 2.4 times over the four years after the crisis involved an evaporation of $5 trillion in the cash generated by banks, according to IMF estimates.

The concern is that QE, by draining markets of the top-rated collateral itself, has a similar effect and offsets the intended injection of new cash into the banking system.

As a result, the ECB's 1 trillion euro cash creation could be dampened by the net removal of bunds and other government bonds that can raise more than twice their face value in cash via repo markets.
