Month & Quarter End Rebalancing: Barclays see weak USD selling

• Barclays: Our passive month-end and quarter-end rebalancing model shows weak USD selling against most majors, and no directional bias against the JPY
• Bank of America: "Estimates suggest JPY GBP outflows vs EUR inflows. Renewed US curve flattening likely to leave global investors over hedged USD; flows seem consistent with current price action. CHF under pressure vs USD & EUR; case for higher USD/CHF beyond rebal window seems clear; fade EUR/CHF as skew favors CHF"

Month-end and quarter-end rebalancing is a recurring, model-driven flow event: custodial and index-tracking portfolios adjust hedges and weights to restore target allocations, and the sell-side banks that publish these estimates (Barclays and BofA among the most followed) disagree as often as they agree because models differ on assumed hedge ratios, benchmark weights, and whether flows are measured by asset performance in local or dollar terms. The split here is typical: Barclays sees only weak USD selling against most majors with no JPY signal, while BofA frames JPY and GBP outflows against EUR inflows and ties the dollar leg to US curve flattening leaving global investors over-hedged, meaning the transmission channel is hedge-ratio adjustment rather than outright asset reallocation. The historical pattern is that rebalancing flows cluster into the final trading days and the London fix, with the quarter-end variant larger and more prone to distorting price action in thinner pairs, and moves frequently retrace once the window closes. The distinction worth drawing is between the mechanical flow and the discretionary thesis layered on top: BofA's call for higher USD/CHF and fading EUR/CHF is a view beyond the rebalancing window, where CHF pressure is attributed to positioning and skew rather than the calendar flow itself. Tells that have mattered in past episodes are the size of the fix-time deviation versus the modelled signal, whether the moves persist into the first sessions of the new quarter, and whether the two banks' divergent JPY reads resolve in either direction. As published estimates rather than observed flows, the signal is indicative, and model revisions late in the month are common.
