There was good news for Portugal on the borrowing front on Wednesday. Despite big anti-austerity protests there last weekend, investors were keen to buy its latest issue of treasury bills - that is bonds due to be paid back in six and 18 months time. And the yields - the amount of interest Lisbon had to offer - fell sharply. The average yield on the 18-month paper slipped below three percent from just over 4.5 percent in April. Analysts said that Portugal was benefiting from a favourable report by the inspectors from the EU, European Central Bank and the International Monetary Fund who last week said the country was on track with its bailout programme.
