Title
Can We Still Blame MBS Hedgers?
Abstract
Part of fixed-income folklore is the idea that directional moves in the rates markets can get exaggerated by the duration-rebalancing decisions of mortgage-backed security (MBS) investors and market-makers. Under stable regimes, we could posit that this theme resides in the market’s “background noise.” In those backdrops, there’s a consensus toolkit for interpreting its effect and how it fits with other price drivers. In periods of harder-to-rationalize repricings in rates space this “convexity effect” attracts more attention: The risk attributes (such as the distribution across the coupon “stack”) of the outstanding “stock” of MBSs and the sector’s relative value are major determinants of the rebalancing strategy, and thus of the effect’s magnitude.
The advent of the Fed’s quantitative easing (QE) programs (currently taking $40 billion of agency MBSs out of private hands per month, net of principal redemptions) and the continuing sell-down of GSE’s balance sheets mean that there’s a significantly reduced amount of MBS paper held by “players who hedge.” Can we still blame the MBS hedgers when we experience greater-than-expected rates volatility?
