* Yen rises broadly as risk aversion increases
* Sterling on the defensive on bleak UK mortgage news
* Euro slips on weak euro-zone PMI data

NEW YORK, June 2 (Reuters) - The yen gained across the board while sterling fell on Monday as investors' risk appetite soured following news of troubles at Britain's largest buy-to-let mortgage lender.
Earlier in the session, Bradford & Bingley <BB.L> issued a stark warning on the state of the UK mortgage market and slashed the price of its emergency rights issue to secure a private equity lifeline, hitting bank shares across Europe.
In the bleakest outlook yet from a British lender, B&B also said it had tumbled to a loss for the first four months of the year. The news came as official data showed approvals for new home loans in Britain hit a record low in April [
]."Risk aversion is back in focus because of bad news out of the UK and therefore we have seen the yen strengthen broadly and sterling weaken," said Matthew Strauss, senior currency strategist, at RBC Capital Markets in Toronto.
The yen tends to get bid in times of heightened risk aversion as investors unwind trades financed by borrowing the Japanese currency at low interest rates.
In early New York trading, the dollar fell 0.8 percent against the yen <JPY=> to 104.70, while the euro slid more than 1 percent to 162.61 <EURJPY=>, reflecting tempered risk appetite as European stocks faltered <
>, led by losses in bank shares.U.S. stock futures also fell, with financial stocks under pressure.
Sterling fell more than 1 percent to $1.9609, hitting one-week lows of $1.9597 <GBP=> after poor UK mortgage news and manufacturing PMI data. The euro also posted sharp gains versus sterling, rising 0.8 percent to 79.05 pence <EURGBP=>.
"The market's nervousness obviously stems from the Northern Rock debacle and the perceived risk that the ongoing deterioration in the housing market will be a bigger problem for UK lenders and the financial system more broadly," said HSBC Bank USA in a research note.
Northern Rock, which used to be the UK's largest mortgage lender, last year fell victim to the credit market squeeze sparked by defaults on U.S. subprime housing loans.
The euro eased as euro-zone manufacturing activity hit its lowest in almost three years. The euro zone's Purchasing Managers' Index of manufacturing in May slipped to 50.6, its lowest since August 2005 [
], underlining slowing growth in the region even as inflation surges.The euro was 0.3 percent weaker versus the dollar at $1.5499 <EUR=>, having struck a two-week low of $1.5460 on Friday.
Despite signs of economic weakness, the European Central Bank has stuck to its position of ensuring inflation does not get out of hand, which suggests it will be wary of cutting interest rates from the current 4 percent to help spur growth.
The dollar continued to garner broad support, having rebounded on the prospect of eventual U.S. monetary tightening from the current 2 percent to deal with inflation.
The euro has retreated some 3 percent from a record high of $1.6018 hit in April, according to Reuters data, with interest rate speculation helping the U.S. currency score back-to-back monthly gains against the single currency in April and May for the first time since early 2007.
U.S. Treasury Secretary Henry Paulson on Monday defended the dollar's status as the world's reserve currency and said its recent decline was only a small factor behind a surge in oil prices [
].Markets are awaiting the release of the U.S. May manufacturing survey from the Institute for Supply Management and April construction spending later in the session. The market expects a small decline in the ISM index to 48.5 from 48.6 and a 0.6 fall in construction spending after a 1.1 contraction decline in March.
