Brazil Central Bank says it will not hold auction to rollover FX swaps on August 21st and will resume deals to rollover FX swaps on August 24th

Brazil Central Bank says it will not hold auction to rollover FX swaps on August 21st and will resume deals to rollover FX swaps on August 24th.

Brazil's FX swap book is the BCB's principal instrument for supplying dollar hedging without touching reserves: the bank pays the domestic rate and receives the FX variation, and rollovers keep maturing notional from falling back onto the spot market. A pause of one or two sessions in the rollover schedule is, on past form, usually operational rather than a policy shift; auctions are routinely suspended and resumed around settlement logistics and market conditions. The distinction that has mattered historically is between a brief gap in the calendar and a sustained reduction in rollover volume: the former passes without consequence, the latter tightens hedge supply, lifts the cost of carrying dollar protection, and tends to steepen the cupom cambial, the onshore dollar implied rate differential. The BCB's track record is to telegraph genuine changes in intervention stance through formal statements rather than through scheduling, so a resumption date already given reads as routine. What bears watching is the size of the resumed auction relative to the maturing stock, since anything short of full rollover has in prior episodes been the first tell of a deliberate withdrawal of hedge supply.
