Same setting (see below), if the swap bank charges 20 basis points, and the TX Instruments and the Japanese Company split the remaining QSD evenly, how much does TX Instruments save? As CEO of TX Instruments you are considering financing your Japanese operations with debt.  US 10-year treasuries are currently at 4.1% and Japanese 10-year treasuries are at 0.75%.  You can borrow at 5.85% domestically (175 bp over the US 10 year treasury) or at 3.0% (225 bp over the Japanese treasury) in Japanese yen.  Assume that there exists a Japanese company that can borrow at 100 bp over the Japanese treasury and at 120 bp over the US treasury. What is the Quality Spread Differential (QSD) in basis points for a swap between TX Instruments and the Japanese company?
