We have now moved to discounting using OIS-SOFR swaps on cleared products and SOFR products in general have picked up in liquidity since last time this question was asked. I'd therefore like to additionally ask (if anyone here is knowledgeable about the exact mechanics of the currently traded USD OIS-SOFR swaps):
1) Which OIS-SOFR tenors are currently the most liquid?
2) For which maturities do the USD OIS-SOFR swaps trade as single-period (i.e. single coupon) swaps, and for which maturities do these trade as multi-coupon swaps? When these are multi-coupon, what is the fixed & floating coupon frequency please?
