At the end of this year, the LIBOR we currently know will be discontinued. For some currencies, the calculation methodology will be adjusted, while others will move to a brand new or alternative risk-free rate (RFR). This also holds for the dollar LIBOR, which will be replaced by the Secured Overnight Financing Rate (SOFR). However, some currencies use the USD LIBOR as a basis for their current reference rates, mainly due to liquidity concerns. Therefore, these FX implied rates face an additional challenge.
