One important measure of sentiment shift can be found in German Bond market.
Last month's "screeching U-turn on bonds" represents another delicate financial bubble that may have just found its pin. Notice, for example, the technical damage that pervades this chart of 8-10 year German bund futures, as prices have plummeted through the lower boundary of a 20-month trend channel.
Also, observe the quick switch in sentiment among bund futures traders. As the market sold off, the Daily Sentiment Index (trade-futures.com) broke away decisively from a long string of plus-90% bullish readings that persisted throughout 2014. It's one of the most dramatic U-turns I have ever seen, and it's the kind of light-bulb moment that frequently occurs at major market turns. With reversals well under way in Europe's weakest borrowers (Portugal, Italy, Greece and Spain), the about-face in the almighty German bund suggests that the credit crunch is now proceeding with a much broader agenda. It should be the start of a long-term trend toward rising borrowing costs.
The swiftness of the bund breakdown generated an equally strong reaction to Mario Draghi's €1 trillion quantitative easing program. "It's as though QE disappeared," said one company CIO, who oversees €197 billion of fixed-income assets (WSJ, 5/7/15) "In one week we had a total unwinding of all QE-related trades." It's exactly the kind of psychological shift, saying that investors would soon view QE as the "worst policy blunder ever initiated by a modern central bank."
Up until now, most pundits believed that a major bond sell-off would be impossible, given the ECB's €60 billion-per-month backstop. The awakening has been particularly rude, as the Wall Street Journal reports that about €344 billion was wiped off the value of eurozone-government bonds. For most European bond funds, all of the gains made so far in 2015 were erased in a matter of weeks.
Still, this is the beginning, not the end, of a trend that will see rising interest rates wreak havoc on Europe's debt-dependent economy. There are many dangers posed by the asset bubbles that have formed in real estate, high-yield debt, British IPOs and bank stocks. But no matter how many bubbles one can identify, the credit bubble underpins all of them. In other words, once credit begins to contract, the air will leak out of numerous inflated assets, most of which investors are now only dimly aware of.
