US Dollar Positioning (IMM Data): Weekly COT Report Analysis

Asset managers are rarely short USD futures, though they have been since Mid April. And while the 11.k contracts of net-short exposure may not sound a lot, it was its record high reached five weeks ago. The 2000 increase of net-short exposure could therefore be deemed as significant, especially since this was before Jerome Powell delivered a speech that was slightly more dovish than expected.

Asset managers have a very low gross-long exposure of 2075 contracts and gross shorts only ticked higher by 187 contracts last week, to 7722. Though we could find that gross-shorts rose considerably more in the next report, and as they do not appear to be at a sentiment extreme is suggests further downside for the US dollar.

JPY/USD Positioning: Japanese Yen Futures – Weekly COT Report

Net-long exposure for the Japanese yen has been in a downtrend since April, though there’s reason to believe bulls may be returning to the table.

Large speculators increased their net-log exposure to the yen for the first week in three, and asset managers increased their by their fastest weekly pace in 18.

And with murmurs of Bank of Japan (BOJ) hikes resurfacing while the Federal Reserve (Fed) veer towards cuts, perhaps it is time for the Japanese yen to regain traction against the US dollar and send USD/JPY lower.

Volatility Index Positioning (VIX): Weekly COT Report Analysis

Traders appear to be anticipating heightened volatility as we head into September, with asset managers pushing their net-log exposure to VIX futures to their most bullish level since October 2022.

Moreover, this heighted level of net bullish exposure has been fuelled by a 7% increase in gross-longs to VIX (+6.2k contracts) alongside a -8.7% fall in gross shorts (-5.5k contracts).

Note the bullish outside week on the VIX futures chart which could also point towards a potential swing low for volatility.
