And don't miss Marcus Ashworth on Jeff Gundlach's dire warning: "Some of the cries of bondageddon stem from a misunderstanding of central bank actions. One catalyst cited was the Bank of Japan's reductions in its bond buyback program, known as Rinbans. This came ahead of a 10-year auction Wednesday and a 40-year auction Friday. But the BoJ is not sending any tapering signals here -- only 10 billion yen ($90 million) was trimmed from each of the 10 to 25-year and 25-year plus buckets. With less issuance from the Ministry of Finance, the BoJ just does not need to buy back as many bonds."
