Currency traders are walking into a packed week. Brazil holds its first-round election on Sunday with the real sitting at the centre of the carry-trade debate, the Federal Reserve releases its meeting minutes on Wednesday, and Japan serves up a double dose of corporate and central-bank clues on Thursday. All of it lands against a backdrop of two-decade-high borrowing costs and oil trading above $100 a barrel.

The Brazilian vote carries the biggest binary risk. President Lula is expected to take a narrow first-round lead but fall short of an outright win, which would send the contest to an October 25 runoff against Flavio Bolsonaro. Brazil's high interest rates have turned the real into a carry-trade favourite, yet those same rates are squeezing households and businesses — and whoever wins inherits a heavy fiscal load that investors doubt either camp can fix.

Stateside, Wednesday's minutes will cover the Fed's September meeting, when the central bank delivered its first increase in three years and signalled more tightening could follow before year-end. Futures traders entered the week leaning toward another hike at the October meeting, though that pricing has cooled after August inflation came in softer than expected and New York Fed chief John Williams said the bank had time to weigh the data.

Why it matters

This week tests whether the dollar's run has room to continue. The dollar index is already at an 18-month high after three straight weekly gains, helped by strong US growth, high yields and elevated energy prices. A hawkish read of the Fed minutes would extend that streak; a cautious tone could hand relief to the euro and the yen. We flagged the greenback's momentum into the weekend when the dollar closed out a fourth winning week over the euro — this week decides if the fifth is on.

For the yen, Thursday matters most. The Reuters Tankan will show how Japanese companies are coping with the energy shock and a weak currency, and it feeds directly into speculation that the Bank of Japan could follow September's 25-basis-point hike with a back-to-back move. Fast Retailing's annual results the same day add a consumer-spending read across Japan and China, with margins under pressure from energy costs and the soft yen.

What to watch

  • Brazil's first-round result on Sunday and whether an October 25 runoff is confirmed.
  • Wednesday's Fed minutes for the balance of opinion on another October hike.
  • Thursday's Reuters Tankan and any signal on the Bank of Japan's October decision.
  • Fast Retailing (Uniqlo) annual results and guidance on margins under the weak yen.
  • France's 2027 budget wrangling, where 10-year yields near 5% are already the highest since 2002.

MarketRadar take

The calendar, not any single headline, is the driver this week. The real's carry appeal can reverse fast if Sunday's result surprises, while the yen's direction waits on Thursday's Tankan and the BOJ. The dollar needs the Fed minutes to stay hawkish to extend its run — anything dovish, and the euro's drop below $1.13 starts looking like a selling climax rather than a breakout. Neutral-to-watchful across the board; this is a week for reacting to data, not anticipating it.
