The logic for the yen to regain its status as a funding currency remains intact. The Bank of Japan maintained its policy rate at 1% in July, and the low-volatility environment also encouraged investors to rebuild short positions. Bloomberg reports that actual funding accounts are still selling yen and allocating to higher-yielding currencies. Bloomberg data shows that the implied yield on the 3-month forward yen is approximately 0.91%, while the Brazilian real is around 12.64%, with an annualized spread of 11.73 percentage points. However, this is only a theoretical arbitrage opportunity, not a locked-in profit; exchange rate fluctuations, hedging costs, and liquidity shocks could all erode the spread. Furthermore, Goldman Sachs stated that further intervention, central bank rate hikes, or a surge in volatility could force concentrated position liquidation.
