Changes in open interest can provide insight as to the strength of the market. I would say the changes can even be more significant in the thinner holiday markets. Take note of the large buying in Feb. 10yr. 114 puts delta neutral in yesterday’s market, it was a liquidating position. There was also liquidation in Jan. 116 puts and a bit in the Mar. 116 puts. As we all know funds have been shorting those puts aggressively. Overnight prices did penetrate that level and quickly rebounded. Sources indicate some real buying by Asian CB’s came in with yields at relatively high levels. This may be significant going into next week’s auctions.
