Rate Ripple

You are the new Governor of the Bank of Brelan, the country's central bank. Your one big tool is the base rate. Raise it or cut it and watch the ripple spread across the high street: loans and savings, mortgages, shoppers, the bike factory's new wing, then prices and jobs a few months later. Keep inflation in the green band without wrecking growth and jobs, and learn when a central bank turns to asset purchasing.
