Yes, aggregation of swaps can provide better liquidity and can save you money. Aggregation of swaps allows you to combine multiple swaps into one larger swap, which can help to reduce transaction costs, increase liquidity, and improve pricing efficiency. This can save you money by reducing the cost of executing multiple swaps and also by allowing you to take advantage of more favorable pricing. In addition, aggregation of swaps can also help to reduce market risk by allowing you to diversify your exposure across multiple counterparties. The fee associated with aggregation of swaps is typically quite small, usually ranging from 2-3%. Therefore, if you can save 200$ by using aggregation of swaps, it is definitely worth considering.
