In a sign of what is expected to be a dismal year for Wall Street bonuses, CNBC has learned this year's bonuses at JPMorgan Chase will be down 30 percent to 50 percent. The news was relayed to the managing directors of the firm's investment bank in a call to review the company's third quarter earnings.

The news is hardly surprising. Investment banking activity has dried up this year. According to Thomson Reuters, through October 10th, mergers and acquisition activity was down 29 pecent from the same time last year, IPOs were down 24 percent, and debt underwriting was down 27 percent. Add to that the S&P 500 is down 35.5 percent year to date and it doesn't bode well for Wall Street's bonus pool.
